Relative Energy Deficiency in Sport – or RED-S as it is known – is caused when there’s a negative balance between dietary energy intake and the energy output needed to promote optimal health, performance, growth and daily life.

Up until 2014 RED-S was referred to as the female athlete triad – disordered eating, menstrual disturbances and low bone density. At this time the International Olympic Committee updated their position statement with the new term (RED-S) to be far more reflective of the wider-spread effects in both female and male athletes – on performance and throughout the body.

In 2018 the IOC published the RED-S Consensus Statement Update.

More than 10% of athletes experience RED-S throughout their career, yet despite its potential to have such adverse effects, RED-S is still only just becoming widely recognised and discussed within a majority of sports.

Symptoms of RED-S

There are many physical symptoms of RED-S, including:

Fatigue
Recurring illness
Difficulties staying warm in the winter and cool in summer months
Poor sleep quality
Stress fractures and low bone mineral density, and impaired accumulation of peak bone mass (PBM)
Weight loss, or below healthy weight
Growth restriction in junior and teenage athletes
Disordered eating or eating disorders such as bulimia or anorexia, orthorexia, restrictive disorders or recurrent dieting/fasting
Digestion issues
Vitamin and mineral deficiencies
Metabolic disturbance
Menstrual disfunction

But REDS can also have far-reaching behavioural and psychological effects as well, including:

Pre-occupation and constant discussion around food
Poor sleep patterns
Restricting or strict control over food intake
Overtraining or struggling to take rest days
Impaired judgement, coordination and concentration
Recurrent soft tissue injury
Irrational behaviour
Fear of food and weight gain
Severe anxiety
Withdrawing or becoming reclusive
Reduction in motivation
Depression

REDS can have an incredibly adverse long-term effect on athletic performance, including an increased risk of injury and decreased training and performance responses. These effects can include:

Decreased muscle strength
Decreased endurance performance
Impaired judgement
Decrease in coordination
Decrease in concentration
Decrease in glycogen stores
Negative impacts on muscle recovery
Poor muscle growth
Increased risk of injury

WHAT ARE THE LONG-TERM EFFECTS OF REDS?

The majority of our bone density is formed during our teenage years. If our bone density formation is impacted during our adolescence or early in our adult years, it can lead to issues with bone weakness and osteoporosis later on in life.

Longer-term, REDS can also have a negative impact on fertility, thyroid function, cardiovascular function, and mental health.

The good news is that most of the negative consequences of RED-S can be reversed if picked up early.

WHAT ARE THE COMMON MYTHS SURROUNDING REDS?

The common perception that athletes with RED-S have an eating disorder is false. Although eating disorders are associated with RED-S not all athletes with eating disorders have RED-S and not all athletes with RED-S have an eating disorder.

It’s true to say that athletes with RED-S can present as underweight- but this is not true in all situations. RED-S can exist without the athlete appearing to be underweight.

RED-S is also not something that just female athletes suffer from. All athletes competing in sports with higher training volumes or weight category restrictions are at a higher risk of developing RED-S. This can include athletes competing in sports that can be judged by aesthetics including figure skating, gymnastics and synchronised swimming, and body weight-dependent sports including long-distance running, mountain biking, and cycling, and weight classed sports such as lightweight rowing and marshall arts.

In one study 44% of ultra-endurance runners were identified as being at risk of developing RED-S while 39% of elite female sprinters should signs of RED-S.

“RED-S can occur in athletes of any competitive status. Among world-class endurance athletes, 37% of females presented with amenorrhea and 40% of males with testosterone in the lowest quartile range indicative of RED-S, which is similar to the reported 40% of Australian female athletes competing at the 2016 Rio Olympic games who were identified as at risk of RED-S. Similarly, among recreational female exercisers, 45% had risk factors associated with RED-S.” (Sports Information Resource Centre).

WHAT SHOULD I LOOK OUT FOR?

The most important piece of advice when it comes to RED-S is – listen to your body. Don’t ignore niggles and definitely don’t skimp on sleep and recovery. You should also:

Monitor menstrual cycles
Think about your relationship with food and/or exercise
Be mindful of your eating patterns: disordered eating to eating disorder.
Notice your exercise dependence
Monitor your behaviour, mood and sleep patterns
Notice change in clothing fit
Be aware of growth and development
Note injuries, illness and gastrointestinal issues
Athletic performance (stagnation-deterioration)
Try to be flexible in your approach

Is cramping cramping your style? In this article, we explain how cramping and hydration go hand in hand and what you can do to avoid issues.

Several factors contribute to cramping. Many athletes have increased their training intensity and volumes but possibly overlooked their nutritional needs to meet their supplementary training requirements.

Go back to the root cause

Dehydration may contribute to cramping in athletes along with imbalances in electrolytes and muscle fatigue.

There are a number of reasons why we may get more dehydrated. In the heat, we lose more sweat and are more prone to dehydration through both sodium and water loss. We also get dehydrated in winter. We often reduce our consumption of salads packed with magnesium-rich leafy vegetables over the cooler months and our natural inclination to drink fluids may also be reduced and our thirst mechanism sluggish over winter.

Coffee, alcohol, and some drugs (such as oral contraceptives) may also accelerate the excretion or reduce the absorption of water and electrolytes such as magnesium and calcium. Not all athletes realize they require 20% more magnesium than a sedentary person.

The adrenal gland churns through sodium, vitamin C, and magnesium when we are stressed. It is pretty rare to find a person who can honestly say they are stress-free, especially in the current environment.

How to stop cramping- a reminder of the basics

Increasing magnesium-rich foods such as spinach, broccoli, squash, peanuts, cashews, almonds, oats, brown rice and cocoa (quality chocolate can be beneficial!) pumpkin seeds, chia seeds, and yogurt may help reduce cramping in athletes. These foods may also ward off more advanced issues linked to magnesium deficiency such as fatigue, immune, bone, or cardiovascular issues.

Most athletes grossly underestimate their daily fluid needs when taking into account fluid losses from training. Endurance athletes are notorious for skipping hydration opportunities during a session (especially long-distance runners) despite large sweat losses. Many athletes are shocked at how many liters of fluid they lose in a single session and ignore the increased risk of nausea, vomiting, diarrhea, and other gastrointestinal problems due to dehydration. However, excessive fluid intake also causes issues such as hyponatremia (low sodium concentration in the blood). Therefore, knowing your sweat rate is the best way to determine how much you should be drinking during and post-exercise.

Calculating your sweat rate can be completed at home by following these simple steps:

1. Weigh yourself just before an intense one-hour session

2. Complete your session and record any fluids you had during the session

3. After your workout towel dry yourself

4. Weigh yourself again in the same clothing you had on for the session

5. The difference between the two weight measurements equates to the fluid lost per hour i.e. 1 liter = 1 kg of fluid lost. If you had fluids during your session deduct this amount i.e. 1kg of minus 200ml of fluid ingested during the run = 800ml of fluid lost.

Companies such as The Sweat Lab provide home-based sweat tests you can order online here

Post exercise rehydration

During recovery, you will continue to lose fluids through sweating and urination. Plan to replace 125-150% of this fluid deficit over the next 2-6 hours. Sip a small amount of fluids constantly over a few hours rather than sculling large amounts at once.

Make sure your daily total fluid intake includes both your exercise-associated requirements and physiological needs. Although we are led to believe 8 glasses is sufficient as a basic requirement, national health associations are now suggesting that 15.5 cups (3.7 liters) for men and 11.5 cups (2.7 liters) of fluids a day for women is more appropriate for adults living in temperate climates. Typically 20-30% of your hydration needs are obtained through water-containing foods and the remainder through liquids.

Athletes with a limited intake of dietary sodium (strictly whole foods diet) may benefit from adding a small pinch of sea salt to evening meals or drink bottles (except athletes with elevated blood pressure).

In some cases where magnesium depletion is significant, a magnesium supplement and adequate electrolytes may be beneficial. As with all supplements, it is best to speak with a health professional to avoid the pitfalls of self-prescribing such as gastrointestinal issues and interactions. Athletes with a history of iron or zinc deficiency should be mindful of magnesium forms. Magnesium citrate is often found in supplements as it is well absorbed and specific to muscles however long-term use may interfere with the carrier protein (ceruloplasmin) and contribute to future mineral insufficiency.

Five quick tips for boosting your overall fluid intake:

1. Keep a pot of warm herbal tea or lemon and ginger in your workspace and sip continuously

2. Enjoy a cup of bone broth, miso or soup as a snack or with dinner.

3. Increase your fluid through foods. Enjoy more “wet” dishes such as soups, casseroles or Vietnamese style Pho bowls and enjoy snacks with high water content such as cucumbers, watermelon, oranges and apples.

4. Add warming herbs and spices such as cinnamon and turmeric to your favourite smoothies or juices (made with room temperature water or warm milk and fresh fruits instead of frozen).

5. Stick to a hydration plan during training sessions and keep a record of total intake daily in your training app or journal.

Tart cherries have been used for decades to treat gout and osteoarthritis, but they also contain phytochemicals which stimulate melatonin, enhance sleep, recovery and sports performance and reduce inflammation.

Tart cherries contain the phytochemicals anthocyanins, flavonoids, flavanols and phenolic acids. Tart Cherries have a higher content of anthocyanins than sweet cherries and contain potassium, calcium, iron, magnesium, vitamins A, C, B6, E, and folic acid. Some sources suggest cherries have 19 times as much vitamin A & beta carotene as strawberries and blueberries!!

Evidence supports tart cherries

A 2016 study involving soccer players found tart cherry juice is efficacious in accelerating recovery following prolonged, repeat sprint activity, movement patterns often seen in soccer, AFL and rugby. The study also supports evidence that polyphenol-rich foods such as tart cherry juice are effective in accelerating recovery following various types of strenuous exercise.

A 2010 study involving recreational male and female runners competing in the London marathon, who supplemented tart cherry juice twice daily for 5 days prior and 2 days after the marathon showed improvements in muscle strength recovery, reduction of inflammatory markers and uric acid. The athlete’s total antioxidant status was 10% greater, while oxidative stress was lower in comparison to placebo.

Studies involving trained cyclists have also shown significant benefits when using Montmorency tart cherry concentrate on reduced oxidative stress, inflammation and muscle damage across 3 days of 109 minutes of road cycling racing when used twice daily for seven consecutive days. They concluded tart cherry juice has direct application for athletes competing in scenario’s where back-to-back performances are required.

How tart cherries help

Tart cherry juice may reduce pain and accelerate recovery after exercise and decreases blood markers of inflammation/oxidative stress in both strength and endurance exercise.

1. Reduces creatine kinase (CK) a pathology marker for muscle damage and breakdown

2. Reduces inflammation -shown in studies by reductions in interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α), interleukin-8 (IL-8), interleukin-1-beta (IL-1-β) and C-reactive protein (CRP),

3. Reduces oxidative stress- it’s ORAC rating of 12,800 is one of the highest in the world.

4. Increases tryptophan, melatonin levels and improves sleep quality.

How to use Tart Cherry Juice for recovery and sleep

Tart cherry juice is unlikely to have beneficial effects during the adaptation/build stage of training, but when there is competition or intense training or multiday tournaments it may improve recovery. Examples of such competitions include: a rugby or AFL tournament, a marathon, a multiday cycling event, triathlon or an ultramarathon.

It is unlikely to be beneficial for consistent use where adaptation to the training stimulus is the athletes’ priority.

General recommendations found in the literature suggest having 30ml of tart cherry juice concentrate in 100ml of water twice daily. This equates to 60-90 cherries per serving.

Tart Cherry juice represents a more convenient way to ingest a large quantity of these polyphenolic compounds without associated side effects such as stomach pain or diarrhoea.

Take the 30ml in water first thing in the morning and in the evening. The evening dose is typically suggested one hour before bed to help facilitate quality sleep, which is of course an athlete’s primary innate recovery tool.

This protocol is suggested for 2-3 days post an event or strenuous training session.

We still need further research and larger studies involving athletes to substantiate claims that a preloading phase of 4-5 days prior to competition is required. It is unlikely that the compounds responsible for its benefits stay in your body long enough to accumulate over many days. Therefore, it remains questionable as to whether the loading phase is really necessary.

What to look out for and where to purchase?

There are many brands of tart cherry juice available online, in health food shops and in supermarkets.

Montmorency and Balaton TC varieties have both been studied; however, most researchers have used Montmorency brands (more predominant and widely available commercially to athletes).

Check the label on the bottle states the juice specifically contains either of these varieties.

The beneficial compounds (anthocyanins) in tart cherries are reduced with heat. Therefore it is important to source tart cherry products that are cold pressed if you wish to maximise the anthocyanin levels and possible benefits. There are a few companies who do this, so check before you purchase.

As a general rule most juices contain around 25 grams of sugar per 250mls but just remember you should only be having 30mls at a time. Low sugar options are available that contain stevia or vanilla extract but generally speaking the sugar content (3 grams per serve) is not an issue for most athletes.

You can expect to pay around $26-28 Aus for organic start cherry juice (450-950ml). The cheaper juices found in chemists or supermarkets are less likely to be cold-pressed.

We hope this information may inspire you to try something new that you may not have otherwise considered. As with all things, moderation and targeted use is more likely to yield desired benefits than overconsumption.

Supplementation by athletes can be a minefield to navigate for the unwary. Whilst there may be significant value in taking additional nutrients, most of us share the view that it should always be a ‘food first’ policy. Maintaining a balanced nutrient–dense diet, is the key foundation for sports performance regardless of the level of competition.

Foods ingested in their natural format contain a package of bioavailable nutrients that help the body absorb key nutrients in ratios that are more easily assimilated than many supplements, and no volume of supplements can make-up for a poor diet. Athletes undertaking regular hard training sessions, may however benefit from taking supplements to maintain nutrient sufficiency and to maintain optimal health.

Supplementation by athletes should ideally focus on only high-quality supplements that are more likely to contain nutrients in beneficial ratios and bioavailable forms. Unfortunately, supplements may not contain all the active ingredients and compounds found in nature. Poor quality (and often cheaper) supplements may contain artificial forms of nutrients that are more difficult for the body to absorb. Retail products may also be formulated in doses below the therapeutic range required for health benefits. The storage and manufacturing processes of some supplements may also be questionable. Investigations of cheaper supplements such as fish oil may be rancid! Supplementation by athletes does have its place. It just isn’t practical to expect anyone to eat 2 buckets of spinach a day! Some nutrients are difficult to obtain purely from food sources when an athlete has high demands, digestion issues, illness, dietary restrictions or nutrient depletion. Iron, iodine, vitamin C and vitamin B12 are just some of the nutrients that fall into this category.

A 2015 study showed up to 70% of athletes use some form of supplement. This study by Outram and Stewart (2015) also revealed between 10-15% of supplements contained banned substances and over 80% did not contain what the label said. Competing athletes are typically aware of known banned substances but some are unaware of the considerable risk of accidental or inadvertent doping through using supplements.

If you are taking supplements and likely to be drug tested either in or out of competition in the future, the general guidelines below may be helpful. Some athletes are currently not in competition but still need to be aware there is no guarantee that taking “at risk” supplements will be out of your system when testing and competition resume.

Avoid imports
Imported supplements purchased online may sometimes appear to be cheaper but come at a huge cost to your sporting career. There are a number of issues to consider. Product quality can be difficult to ascertain due to being produced under different standards and labelling laws from those imposed on us from the Therapeutic Goods Association (TGA) in Australia. All ingredients may not be listed on the label of an imported product and this may put athletes at significant risk of testing positive to a banned substance. In the USA, dietary supplements are classified as a subcategory of food, exempting manufacturers from providing pre-market evidence of product safety and efficacy. The U.S. Food and Drug Administration (FDA) cannot inspect supplements until after the products have entered the marketplace and some disreputable manufacturers have spiked products with drugs such as anabolic steroids and amphetamines.

Know your banned substances
Always check labels and know the banned substance list for your specific sport both in and out of competition. The list of banned drugs and substances can be found on the ASADA website and substances can be checked here. If you are likely to be competing internationally, it would be wise to also look at the WADA guidelines here. Just because the substance does not appear on the prohibited list, does not mean it is 100% ok to ingest. The rules change frequently and supplements and other over the counter drugs may have different names from what appears on the list. Substances such as Bupropion, caffeine, nicotine and phenylephrine are included in the WADA 2020 Monitoring Program and their status may change at any time. If in doubt, avoid the substance.

Health foods and natural products
Some health food products and herbal medicines should still be avoided even if they are not on the banned list if you are unable to be assured of their purity and quality. For example, maca powder taken to support hormone function, energy and sports performance is one natural food product that is at risk of contamination. Tribulus is another product to be weary of. The Australian Institute of Sport (AIS) states “these products do not appear on the WADA list and are thus not specifically banned. However, they are often found in multi-ingredient products that contain banned ingredients or are at high risk of being contaminated. Therefore, they are not recommended for use.” See the AIS Supplement Group D list here .

Supplementation by athletes -Consider certified
Common sports supplements such as magnesium, probiotics, vitamin C, protein powders, creatinine etc. are now being batch tested and certified. Human and Supplement Testing Australia (HASTA) is an Australian commercial product testing organisation for WADA and has a certification scheme. Certifying a product involves not just multiple batch testing, but verification of the manufacturing quality controls that are in place and site inspections. If a product has been “HASTA Certified” it means that every batch has been tested for over 200 WADA prohibited substances.

Informed Sport also conduct supplementation testing on international sports nutrition brands. You can read more about the Informed Sport certification process here and HASTA process here

The same supplements should not be more expensive than usual just because they are batch tested.

Are there any guarantees?
No. Supplements screened by Hasta and Informed Sport cannot offer a 100% guarantee that an athlete will not test positive, but they are significantly less risky than other supplements. As batch testing is very expensive, limited supplements are available despite some manufacturers having large product ranges. If you have purchased a Hasta certified product, always check your supplement bottle has been batch tested. If your supplement does not come with a Hasta certificate, you are unable to safely assume it has been batch tested.

Are certified products better quality?
Unfortunately no. Companies that can afford to undertake the rigorous and expensive certification process may have some products included. Smaller companies that produce high quality products, may not be on the list. Just because a product is certified, does not mean they are suitable for you. Athletes still need to choose supplements with bioavailable forms of nutrients and take sufficient amounts to reach therapeutic levels and health benefits. There are Hasta certified products from reputable companies that I recommend frequently but it may be difficult for an athlete to choose suitable options if they just scroll through the list of supplement options.

Therefore, if you are a competing athlete, we suggest always checking with a qualified practitioner before self-prescribing any supplement, even if it appears to be batch tested or packaged as ‘food grade’ at the health food shop. Batch tested supplements are available through the Athlete Sanctuary.

We hope you found this information useful. If you would like further guidance with your supplementation protocol or health concerns, please get in touch.

Some women experience absolutely no symptoms during their transition through menopause but if you are like 80% of women who do, it’s reassuring to know there are treatment options available. Help for menopause is here.

Perimenopause is the stage where most of the symptoms begin and these can persist for over a decade. Menopause officially commences 12 months after your last period. Women can go through menopause anywhere between the ages of 40 and 58 years but the average age is 52 years. Symptoms can occur due to the falling levels of estrogen and progesterone, which has a multifaceted impact on organs and tissues throughout the body.

Most women identify menopause with hot flushes, night sweats, vaginal dryness, mood swings, poor libido and fatigue. Symptoms usually occur in the perimenopausal phase due to declining progesterone. Oestrogen actually increases to levels 30% higher than before but can go through periods of variations similar to a roller coaster leading to insomnia, depression, poor concentration, irritability, anxiety and poor stress tolerance and lethargy. In the later stages of perimenopause, oestrogen declines which may contribute to other symptoms such as heart palpitations, joint pain, osteoporosis and mental health issues.

One of the associated effects of estrogen decline is an increased risk of osteoporosis. This is due primarily to the 1-2% loss of bone density per year of menopause, as well as 10 years post-menopause. Estrogen decline is also associated with elevated cholesterol, cardiovascular disease, hypothyroidism, urinary tract infections and thrush.

Some women have concerns about the use of hormone replacement therapy (HRT) or are unable to use this option due to breast or ovarian cancer risk. Fortunately, there is now a large body of evidence that supports the use of herbal and nutritional medicines during the menopausal transition.

DIETARY INTERVENTIONS

Phytoestrogens are naturally occurring estrogen-like compounds found in plants, fruits, or vegetables and are commonly divided into three main classes: isoflavones, lignans, and coumestans.

Isoflavones are found in the legume family, with high amounts in soybeans and soy products.

Lignans are found in high-fibre foods such as unrefined grains, cereal brans, and beans, with flaxseed being a particularly good dietary source of lignans. A recent systematic review found that women who consumed protein bars containing flaxseed (410 mg of lignan) for 6 weeks reported a 50% decrease in hot flushes. Seed cycling can be helpful for women who want to boost their intake of fatty acids and lignans.

Coumestan-rich foods include alfalfa and clover sprouts, peas, pinto beans, and lima beans.

Herbs

Hops (Humulus lupulus) dampens tension and anxiety. The active ingredient in hops, 8-prenylnaringenin, is a potent phytoestrogen and has been demonstrated to reduce vasomotor symptoms by improving the ability of the blood vessels to expand and contract. Numerous clinical trials have also documented significant reductions in the frequency of hot flushes, sweating, insomnia, heart palpitations and irritability in women who used a hops extract for 6 weeks.

In clinical practice, a combination of herbs is often used to support women during the transition through menopause. Korean ginseng (Panax ginseng), which is considered to be a “buried treasure medicine”, is another popular herb for active women suffering from fatigue. Ginseng’s active constituents include saponins, amino acids, vitamins (particularly folic acid and niacin), alkaloids, phenolic compounds, and flavonoids. Ginseng has been widely used in traditional medicine to assist with building resilience to stress and used as an energizer, to increase libido, and testosterone and alleviate menopausal symptoms. Clinical trials have shown ginseng significantly reduced depression and improve perceived well-being, exercise performance and energy in perimenopause.

Another popular herb is chasteberry, or vitex. This herb has shown positive results in reducing PMS, anxiety, hot flushes and breast tenderness in perimenopausal women. Vitex is used to support the transition from perimenopause to menopause due to its ability to increase progesterone levels and help maintain a healthy balance between progesterone and estrogen.

For women experiencing persistent hot flushes or night sweats as a result of menopause, Red Clover (Trifolium Pratense) may often be prescribed. This herb contains high levels of phytoestrogens for improving hormonal balance, as well as helping improve bone density in those at risk of osteoporosis. Several clinical trials demon straight the isoflavones present in red clover inhibit bone resorption and therefore reduce bone turnover associated with osteoporosis.

Ginkgo Biloba is similar to red clover because of the phytoestrogens it contains and its ability to naturally elevate estrogen levels. Studies show that Ginkgo Biloba can reduce mood fluctuations associated with both PMS and menopause, as well as improving libido in 84% of trial participants after 4 weeks.

Sage, most commonly prescribed as a tea, has long been used in the management of fevers. However, there is also evidence to support the use of sage for menopausal hot flushes and night sweats. A study that assessed the use of fresh sage leaves in food or as tea demonstrated that the intensity and frequency of hot flushes were significantly reduced over a period of 8 weeks with consistent use.

Hormones play an integral role in your health, and changes in hormone balances can be challenging. There are many different ways that nutrition can be used to navigate menopause, without having to experience the numerous, negative side effects of HRT.

As with any element of health, there is never a one-size-fits-all approach and therefore we recommend individualised treatments for menopausal symptoms.

Choosing the best collagen for tendon repair can be challenging. There are so many to choose from. All collagen powders are not created equal. Understanding the different forms and their sources can be helpful when making your decision. Keep in mind collagen can be helpful in the repair of tendons, bones and ligaments, improving skin elasticity and gut health.

Recent studies have helped to fine-tune dosage recommendations and nutrient combinations to enhance its effectiveness. As the quality and volume of collagen produced by our body reduces with age, master athletes may benefit from consistent supplementation.

What does collagen do?

Collagen is a major structural protein and building block made within your body. Collectively, collagen comprises 30% of the body’s protein as amino-acids, specifically glycine, proline, hydroxyproline and arginine. Collagen provides structure and acts like glue to your skin, hair, skeleton, tendons, muscles, ligaments, corneas, teeth and blood vessels. Hydrolysed collagen is similar to gelatin but structurally varies. Collagen contains tri peptides whereas gelatin contains simple amino acid chains. Peptide chains within collagen act as signalling molecules to fibroblasts which increase collagen, elastin and hyaluronic production. They also signal anti-inflammatory agents and increase the production of antioxidants.

There are 29 different types of collagen, all with slightly different roles but 80 – 90 % of the collagen in the body consists of types I, II, and III. Together all forms serve the same purpose; to help tissues withstand stretching. Although all forms are essential in the body, research tends to focus on types I-III when it comes to athletes. Let’s explore these three types in a little more detail.

Type I forms the reinforcing rods in bone, cartilage, tendons, teeth and connective tissue and is the most dominant form within the body making up 90% of all collagen. It is also the collagen that forms scar tissue and skin.

Type II (also known as hyaline or articular cartilage) is the major collagen in elastic cartilage and is the gel like substance designed to provide cushioning and allow joints to absorb shock. Its rigid macromolecules provide the strength and compressibility that allow it to resist large deformations in shape during movement.

Type III supports the structure of muscles, organs, and arteries.

Collagen and vitamin C for repair – the research evidence

Recent studies have also shown the combination of 500mg of vitamin C and between 5 – 15 grams of collagen is beneficial when taken one hour before exercise. Positive results do not appear to be dose dependent when within this range. Several studies including a study from the AIS (Australia Institute of Sport) showed significant improvements in achilles tendon injuries when taken for three to six months.

A 2017 study also demonstrated significant improvements in activity-related joint pain in 139 athletes, positive changes to ankle function and pain following supplementation for sprains. Collagen also reduces the risk of subsequent sprains for 3 months after supplementation.

Most collagen powders on the market are derived from shellfish, beef, chicken or pork. As a general recommendation, better quality collagen supplements are derived from grass-fed animals or wild-caught seafood. Vegans should be aware plants do not make collagen. There are currently no clinical trials that support bone broth as a reliable source of collagen peptides.

Vitamin C

Vitamin C converts proline and glycine to hydroxyproline. Pre-clinical studies have also shown vitamin C has the potential to accelerate bone healing after a fracture, increased type I synthesis, and reduce oxidative stress.

Additional dietary intake of vitamin C-rich foods during rehabilitation may also be beneficial. Good sources include berries, red capsicum, broccoli, kiwi, guava, citrus, rosehip and indigenous foods such as camu camu, goji berry and Kakadu plum.

Other beneficial nutrients

Copper also plays a role in production as it activates an enzyme called lysyl oxidase that is required for maturation. Copper is found in beef liver, crab, oysters, sunflower and sesame seeds, cocoa powder, cashews, hazelnuts, peanuts, almonds and lentils.

Zinc helps with the production and activates a protein that re–models collagen during wound healing. Zinc is found in seafood, oysters, pepitas, nuts, poultry and meat.

Manganese activates enzymes such as pro–lidase that your cells use to make proline and gives collagen fibres their shape. Brown rice, oats, pineapple, peanuts, and pecans all contain manganese.

Amino Acids

Insufficient protein intake or overall energy intake impedes wound healing and increases inflammation to possibly deleterious levels. During the healing process, energy expenditure is increased, particularly if the injury is severe. Energy expenditure may increase between 15% – 50%, depending on the type and severity of the injury.

Given that muscle loss may begin from inactivity during an injury recovery phase within 36 hours and healing processes are heavily reliant on synthesis of collagen and other proteins, the importance of dietary protein should not be understated. If you are in the unfortunate position of being injured, protein intake of 2 grams/ kg of body weight per day is advocated.

Meat, poultry, seafood, dairy, legumes, and tofu are all excellent sources of amino acids. Plant-based athletes may combine protein sources to ensure all essential amino acids are available for protein synthesis.

In addition, specific foods rich in proline and glycine may be beneficial.

Proline is found in egg whites, wheat germ, dairy products, cabbage, asparagus, and mushrooms.

Glycine is found in the skin of pork or chicken and gelatin.

Making your own gelatin chews are an easy way to boost glycine intake.

Gelatin is what is used to set jelly and gummy lollies. Gelatin also contains proline, valine and glutamic acid.

Be wary of sugar! Sugar interferes with collagen’s ability to repair itself and degrades collagen. It is therefore a good idea to limit your consumption of added sugar and refined carbs when injured for several reasons.

Please remember the guidelines provided in this blog are general in nature. If you are injured, you may benefit from individualised nutritional guidance to help you get back on track. Make an appointment here

Vitamin D deficiency has consequences well beyond bone health.

Vitamin D is gold.

Vitamin D is so important to the body, immune cells, brain, colon, breast, and other cells have the ability to also activate it locally when required. Although labelled a vitamin, calcitriol (bio-active vitamin D) acts more like a hormone within the body. It is involved in many essential functions well beyond bone health. Vitamin D is critical for inflammatory modulation, hormonal and immune functions as well as cardiovascular, mental health and pancreatic function. The active form of vitamin D interacts with receptors in the intestine, bone, brain, heart, immune cells and skeletal muscle. Vitamin D functions as a modulator of up to 1000 genes involved in cellular growth and protein synthesis.

Vitamin D plays an important role in an athlete’s health, training and performance.

Studies show it may even be necessary for optimal muscle function and performance as muscle performance is impaired by suboptimal vitamin D status. Deficiency induces atrophy of fast twitch muscle fibers, impairs calcium uptake and prolongs time to peak contractile tension and relaxation. Studies also show Vitamin D deficiency may delay rehabilitation from injury.

In sporty pregnant women, low vitamin D levels are linked to pre-eclampsia, gestational diabetes and adverse pregnancy outcomes. Vitamin D also plays a part in regulating insulin, blood sugar balance and thyroid hormones. Research shows that a deficiency of vitamin D is associated with a high risk of thyroid antibodies, which are found in individuals with autoimmune thyroid disorders.

Vitamin D is most commonly known in the athletic community for its influence on bone health and prevention of bone injury. Vitamin D influences bone health by upregulating expression of genes that enhance intestinal calcium absorption, and reabsorption by the kidneys along with increasing bone-building cell activity. Studies show calcium absorption significantly increases when vitamin D levels are sufficient. Calcium absorption is reduced to 10-15% with low vitamin D levels and stress fracture risk significantly increases.

Typically, 80% of our vitamin D is obtained from the sun and 20% from food sources.

Signs of Vitamin D deficiency

fatigue and tiredness
lower back pain
recurrent colds and infections and poor immunity
stress fractures
heaviness in the legs
recurrent injuries
muscle pain, weakness, poor muscle contraction and relaxation
mental health issues, low mood, seasonal sadness and depression
hormonal imbalances and PMS
anaemia and low iron
pale floating stool
photosensitivity

According to Sunsmart Australia, one-third of Australians are low in Vitamin D.

10 Reasons your vitamin D is low

Vitamin D can be made by our body when skin is exposed to sunlight through a complex activation process, however, what many people fail to realise is that this process doesn’t always occur efficiently or reach levels required for optimal health. Vitamin D production may vary depending on the time of day of sun exposure, season, cloud cover, smog, latitude, skin pigmentation, age, and sunscreen use.

We often see patients with low levels of vitamin D despite being out in the sun daily. There are several reasons why vitamin D levels drop despite sunlight exposure.

1. As vitamin D is fat-soluble and stored in fat cells, individuals with low body fat, may be disposed to vitamin D deficiency as their storage tank is smaller.

2. Activation and production of vitamin D are inhibited by magnesium deficiency, inflammation, and excessive use of sunscreen.

3. Individuals with any form of malabsorption issues, liver or kidney issues, coeliac’s disease, Crohn’s, vegans, and thyroid issues can be prone to deficiencies.

4. Anyone with a history of anaemia should also be aware of the bidirectional influence between iron and vitamin D. The activation of vitamin D in the kidneys requires iron-containing compounds ferredoxin reductase and ferredoxin. Iron deficiency may therefore contribute to the inactivation of vitamin D. Vitamin D deficiency may also be associated with higher hepcidin (a pro-inflammatory mediator) in the liver. Hepcidin will elevate ferritin stores and down-regulate intestinal absorption of iron from food and impair storage iron release. Hundreds of athletes have used our handy anaemia tool to help determine the likely risk of having low iron or anaemia.

5. Diets containing limited seafood, eggs or dairy such as vegan diets may also reduce vitamin D intake.

6. Insufficient direct UVB exposure (due to smog, cloud cover or latitude), early- or late-day training, indoor training, geographic location further away from the equator and sunscreen use (SPF of 15 lowers vitamin D synthesis capacity by 98%).

7. Disruption to the microbiota and gut inflammation may also affect the availability of vitamin D.

8. In addition some individuals may find it difficult to increase their vitamin D levels if they have low antioxidant status.

9. Medications such as anticonvulsants, corticosteroids, cimetidine, theophylline, statins or the weight loss drug orlistat.

PATHOLOGY TESTING

As a general guide, Osteoporosis Australia recommends most people should have levels of at least 50 nmol/L at the end of winter, which means people may have higher levels during summer (60-70 nmol/L). However, in order to maintain optimal health, athletes should aim for serum levels over 90 nmol/L ideally between 100 and 130 nmol/L.

Treatment

Daily sunlight exposure on your skin especially on large areas such as the back, chest, legs and arms (25-60 minutes in winter) without suntan cream, is a great way to keep levels topped up. Athletes living in southern states of Australia and New Zealand need 30 minutes of direct skin exposure (springtime) on large areas of skin such as back, arms, chest or legs closer to midday. Athletes living closer to the equator may require 15 minutes before 10 am. During this time avoid putting sunscreen on, then for the rest of the day, cover up. Lunchtime exercise with as much skin exposure as possible (within decency) is a great way to give yourself a vitamin D fix, especially in winter months.

Get tested biannually- before winter and again in spring.

Consume vitamin D-rich foods on a daily basis such as oily fish like cod, salmon, sardines or tuna, egg yolks, sun-dried mushrooms, and fortified milk, butter and fortified cereals. Some individuals may benefit from cod liver oil which also contains vitamin A and essential fatty acids.

When levels are low, take a quality supplement in the correct dosage range and a probiotic. Certain probiotics such as Lactobacillus rhamnosus LGG and Lactobacillus plantarum enhance levels synergistically.

Obtain adequate magnesium-rich foods such as spinach, pumpkin seeds, almonds, black beans, oyster mushrooms, avocado, figs, yogurt or kefir and banana. Chocolate also contains magnesium.

Mineral and heavy metal testing can help to gain a better understanding of what metals may be impacting on health and what minerals are required to increase to enhance performance and overall health. Optimal nutritional balance is essential for the function of every cell and system in your body. Obtaining feedback on mineral absorption is just one of the benefits of mineral testing for athletes.

Mineral testing provides a wider perspective on an individual’s overall health status than just urine, blood or stool pathology testing alone although it is always useful to use both tests in conjunction with each other. Mineral testing can be used as an early detector of subclinical issues and provide useful guidelines in terms of how to best support the body when annoying symptoms such as fatigue, insomnia and digestion issues persist.

In clinical practice, test results are always accompanied by a thorough assessment of your overall health and nutritional intake to provide meaningful context to data and to give you a clear understanding of where and how deficits may be occurring.

A mineral analysis may provide insight into your current health status, identify potential areas of concern and provide suggestions around dietary and supplemental measures that may improve your health now and prevent issues in the future.

Mineral testing for athletes- useful insights

Mineral testing provides a snapshot of how the body is utilizing the nutrients obtained from your food and provides an analysis of 13 key minerals. Trends in nutrient deficiencies or excessive mineral levels may indicate poor activation and non-beneficial storage of nutrients.

To demonstrate this point, let’s take a look at calcium. Calcium will be maintained within a very narrow range in blood serum due to its life-supporting roles in managing heart rate, nerves, and muscle function. However, in a mineral analysis high or levels of calcium may be observed. Low levels of calcium may indicate poor absorption, inadequate intake or other nutrient issues such as low vitamin D, while high levels may be suggestive of low vitamin B6 and poor calcium utilisation in the body.

High calcium levels may also contribute to underactive thyroid issues with symptoms such as weight gain, fatigue, low blood pressure and poor mood. Early detection of calcium issues is vital for the prevention of bone issues such as osteopenia, fractures, bone spurs, kidney stones and thyroid issues.

Mineral testing for athletes provides an analysis of how the body is utilizing 13 key nutrients obtained from the athlete’s diet. Longer-term patterns in nutrient deficiencies or excesses may indicate poor activation and non-beneficial storage of nutrients.

High levels in mineral testing for athletes, may be suggestive of low vitamin B6 and poor calcium utilisation in the body.

Significance of mineral testing for athletes

A clinical understanding of how an individual metabolises and utilises nutrients can be obtained through various mineral ratios included in a mineral test. Just some of the ratios contained in the mineral analysis report are outlined below:

Immunity: Low zinc in relation to high copper levels may indicate a susceptibility to viral infections such as colds, cold sore outbreaks or poor wound healing. Zinc is critical to immune cell function and digestion and hydrochloric acid. Reduced digestive function and symptoms such as bloating, diarrhoea, malabsorption and low nutrient levels may also be observed in patients with low zinc.

Iron deficiency and anaemia: As discussed previously in relation to immunity, ceruloplasmin is a protein carrier shared by zinc, copper and iron. If zinc, copper or iron are too high, they may inhibit the absorption of the other minerals. For example -high levels of copper may be observed in women taking the oral contraceptive pill or through drinking water carried in copper pipes. High copper levels may contribute to iron deficiency anaemia and present as shortness of breath, lethargy, dizziness and exercise fatigue.

Poor liver detoxification: Molybdenum is a key nutrient required for liver detoxification and is frequently low on test results due to reduced intake of foods rich in molybdenum such as legumes. When molybdenum is low in relation to sulfur an individual may experience sluggishness, fatigue, skin issues, and poor recovery related to reduced sulfation detoxification pathways in the liver.

Blood sugar control issues: Manganese and chromium are key nutrients required for blood sugar control. When manganese is low in relation to chromium an individual may experience energy dips, especially after meals, sugar cravings and dizziness or sweating related to poor blood sugar control and fluctuating insulin levels.

Hormone issues: Minerals play a key role in hormone modulation. When iron is low in relation to copper, individuals may complain of fatigue, poor recovery, weakness, loss of libido, irregular periods and hot flushes due to a pattern of low progesterone or testosterone.

Adrenal gland insufficiency: During times of stress, the adrenal gland utilises larger amounts of sodium and magnesium. When sodium levels are low in comparison to magnesium the adrenal gland may be underperforming as it is highly sodium dependent to produce key hormones such as cortisol.

General muscle tightness: Calcium and magnesium are required for bone health and muscle and nerve function. Stiff muscles, bladder issues and immobile joints may present when there is an issue between the ratio of calcium and magnesium in the body.

HEAVY METAL BURDEN
This form of testing may also identify heavy metal burden on the body. Despite a clean lifestyle, individuals can present with unfavourable levels of mercury, arsenic, lead, tin or aluminium largely due to living in a modern environment where exposure to heavy metals occurs on a regular basis.

Contrary to popular belief, heavy metal accumulation does not necessarily occur from occupational exposure. Frequent exposure arises from pesticides; additives and the tinning of foods; dental fillings; drinking water; products and materials used in homes and offices; personal care products and cosmetics.

Heavy metals are neurotoxins and may over time contribute to a plethora of health issues such as thyroid, reproductive and mental health issues, and cancers. Heavy metals displace other key minerals such as zinc, selenium and iron. The presence of these metals may also be indicative of other functional issues such as reduced liver detoxification pathways.

Practicalities of mineral testing for athletes

Mineral testing looks at long-term trends (over 2-3 months) and can be very useful when symptoms or health issues are ongoing and underlying contributing factors are yet to be identified. Athletes also find mineral balance results useful before they launch a new training campaign as a measure of nutritional status and as a preventative measure against deficiencies that may inhibit performance.

Mineral testing does not require a blood draw and can be conducted in the privacy of your own home. Test results generally take 2 weeks and are reviewed during an extended consultation.

Photo of seed products useful for seed cycling during the menstraul cycle for women

Before we get stuck into the detail, let’s do a quick recap on how seed cycling supports hormones.

Female hormones are regulated through complex signalling and feedback mechanisms. Signals are received and then transmitted by the hypothalamus part of the brain out to the pituitary gland, adrenal glands and then ovaries (the HPAO axis). In times of change or increase physical or emotional stress of any kind, the HPOA axis can become dysregulated.

Symptoms such as longer or irregular menstrual cycles, hot sweats, increased PMS, mood changes, fatigue, changes in bleeding and reduced ability to handle training intensity may appear. These symptoms frequently occur when there is no known structural or functional issue with the ovaries.

In order to reduce symptoms, some women reach for pharmaceutical medications without understanding or being aware they have the potential to further dysregulate long-term hormonal balance and deplete nutrients such as zinc and magnesium.

In addition to medicinal herbs such as Chaste Tree, Schisandra, Kudzu or Rhodiola, seed cycling may provide subtle hormonal support by boosting estrogen levels in the first part of the cycle and progesterone levels in the second part without the possible side effects of other medications.

THE PROCESS

Seed cycling supports hormones by providing nutrient rich foods in the form of seeds at different times of the menstrual cycle.

How to seed cycle
Preparation
Combine ¼ cup of each of the following seeds nominated to the two phases of your cycle. Take your seeds (according to which phase of your cycle you are in) and whiz them in a coffee grinder to break the seeds down into a meal-like consistency. Make 2 separate jars of seeds.

Follicular phase day 1-14 of your cycle (or until ovulation)= flaxseed + pepitas (pumpkin seeds)
Luteal phase day 15-28 of your cycle (or post ovulation) = sesame + sunflower seeds

Dose: 1-2 tablespoons of combined ground seeds daily.
How: Add seeds to smoothies, on top of breakfast oats, avocado toast, coconut yogurt or as a garnish on savoury soups, salads or scrambled eggs. Seed cycling biscuits or brownie mixes are also a great option. Choose whole, organic seeds instead of pre-ground seeds where possible.
Storage: Store ground seeds in an air-tight jar in the fridge to preserve their essential fatty acids from oxidation.
Duration: Most women need to allow 3-4 cycles before expecting changes to occur.

An easy way to ensure you have the right seeds across the month is to purchase a seed cycling kit.

Green tea is just one of several teas beneficial for athletes. Packed in antioxidants, green tea is considered to have the highest polyphenol and therapeutic effects because it remains unoxidised during processing, where-as the other tea leaves are oxidised. Green, black and oolong tea is produced from the same plant Cameliia sinensis but their taste, constituents and colour vary depending on how the leaves are processed.

Green tea is packed with antibacterial agents and the phytonutrients also help counteract inflammation. Regular intake improves tendon, cartilage and collagen health in athletes.

Types of green tea

There are lots of different kinds of green tea depending on growing and harvesting methods. Our favourite is a Japanese tea called Genmaicha “brown rice tea” which is blended with roasted popped brown rice. The sugar and starch from the rice cause the tea to have a warm, full, nutty flavour without bitterness. It is considered easy to drink and can soothe an upset stomach.

Other popular options include the Japanese varieties of Sencha and Jasmine (which is often mixed with white and black tea).

Better than coffee

Green tea is an excellent substitute for coffee drinkers. Although the average cup of pure green tea usually contains around 25 milligrams of caffeine, this is considered to be a low amount of caffeine when compared to around 100-180 milligrams in a typical coffee.

So often athletes get a false sense of energy when they are pumped full of caffeine. Over the long term, this can set them up for adrenal fatigue, over-training issues, nutrient depletion, dehydration and chronic injuries. Green tea provides a great “pick me up” without flogging the adrenal glands. To further reduce your daily caffeine load, and avoid sleepless nights, you may like to consider these tips:

Get the most out of green tea

Avoid consuming green tea or other caffeine-containing foods or beverages after lunchtime
Opt for low-caffeine teas or other herbal teas like Rooibos tea.
Drink blends. A blended tea such as a 50-50 blend of lemongrass or mint and green tea usually contains about half the caffeine of its unblended counterpart.
Brew tea correctly. Many people use boiling water to brew tea for more than three minutes. This increases the level of caffeine in your cup. Instead, brew with simmering water for one-and-a-half minutes to three minutes.
Reuse the original tea leaves for additional cups of tea that will taste the same but contain less caffeine.
Drink whole-leaf tea instead of tea bags. Teabags have more caffeine than loose-leaf tea (usually).
Avoid powdered teas high in caffeine. Matcha is one tea to avoid if you are trying to reduce caffeine as it usually comes in a concentrated form and is made from powdered green leaves instead of an infusion of the leaf. Therefore, Matcha has much higher levels of caffeine than other green teas.
