Biomarkers
Sort By:
Arg
ArginineArginine is an amino acid that plays a role in protein production, tissue repair (e.g. wound healing) and immune cell function. Arginine enables the production of nitric oxide (NO) which is involved in the regulation of blood pressure and acts as a vasodilator, allowing better blood circulation. This amino acid is involved in the formation of creatine and in the detoxification of ammonia, an extremely toxic substance for the central nervous system.
Asn
AsparagineAsparagine is an amino acid involved in the production of cellular proteins and in maintaining the balance of the central nervous system.
BCAA
Branched-chain amino acidsBranched-chain amino acids (BCAA) consists of 3 essential amino acids (leucine, isoleucine and valine) that play a major role in the regulation of protein production (such as muscle development) and participates in the synthesis of glutamine. BCAA deficiency may lead to dizziness, headaches, depression, confusion, irritability, and muscle tremors.
C18:1
Oleic acidOleic acid is part of the monounsaturated fatty acid (MUFA) family. It plays a role in maintaining membrane fluidity and is needed for the structure of cell membranes, including the myelin sheath that protects nerve fibers.
C18:2
Linoleic acidLinoleic acid is an essential omega-6 fatty acid, meaning our body cannot produce it so it must be obtained through the diet. Linoleic acid plays a role in the structure of neuronal membranes and participates in preserving nerve blood flow.
Car
CarnitineCarnitine plays an important role in the production of energy since it participates in the transport of fatty acids into the cells, where they are used to generate energy. Carnitine requires many co-factors to function such as magnesium, iron, vitamin C, folic acid, and vitamins B3, B5, B6 and B12. Carnitine deficiency leads to symptoms such as muscle weakness (especially during exercise), shortness of breath, symptoms of hypoglycemia (low blood sugar), disorders of lipid metabolism, and heart problems.
Cit
CitrullineCitrulline is a non-protein amino acid that has antioxidant properties and plays an important role in detoxification metabolism. It increases the availability of arginine for the production of nitric oxide, a molecule which has important functions in the immune system's reaction to infections and that acts as a vasodilator (meaning it helps blood vessels relax).
Cu
CopperCopper is a trace mineral, which means your body only needs little amounts. Adequate amounts of copper are required for physical training and performance. Since it is involved in iron metabolism, in the formation of hemoglobin and in energy production, copper may delay exhaustion time, enhance endurance, and speed up recovery from sports injuries. Copper also plays important roles in the activation of the immune system, the regulation of blood pressure, the maintenance of the myelin sheath that protects nerve fibers, and the formation of healthy bones, teeth, and heart. Copper also acts as an antioxidant, which means it protect cells from oxidative damage.
DHA
DHAHigh-intensity exercise generates free radical compounds which in excess, lead to an inflammatory state. Healthy levels in DHA support proper anti-inflammatory processes to reduce inflammation. DHA participates in supporting intestinal barrier integrity and can modulate the adaptive immune response, especially antiviral. It also serves as a precursor for different compounds needed for example to support healthy respiratory function.
EPA
EPAHigh-intensity exercise generates free radical compounds which in excess, lead to an inflammatory state. Healthy levels in omega-3 EPA (Eicosapentaenoic acid) support proper anti-inflammatory processes to reduce inflammation. EPA participates in supporting intestinal barrier integrity and can modulate the adaptive immune response, especially antiviral. It also serves as a precursor for different compounds needed for example to support healthy respiratory function.
Gln
GlutamineGlutamine is an amino acid that represents a major energy source for intestinal cells and helps maintain the integrity of the intestinal barrier. Glutamine plays a role in protein synthesis and in supporting your immune system during times of stress, including during prolonged and intense physical exertion and high-intensity strength training. It is also a precursor of glutathione, an intracellular antioxidant that protects cells from oxidative damage. When glutamine reserves are depleted, you may experience a decrease in strength, endurance and recovery. As glutamine accelerates glycogen synthesis, it is best to consume it after a training session.
Mg
MagnesiumMagnesium is a crucial mineral for your body It is implicated in several functions and in hundreds of metabolic processes, including muscle contractions and relaxation, protein synthesis, regulation of blood pressure and body temperature, secretion of parathyroid hormone (which helps control the levels of calcium in the blood), and transmission of nerve. Magnesium supports the body against the stress of exercise and may prevent muscle spasms and cramps during intense training or competition. Symptoms of magnesium deficiency include muscle tension and cramps. Athletes lose magnesium through sweat and urine and a higher intake is recommended than for sedentary persons. Exercising in hot environments, which leads to more sweating, increases the needs in magnesium.
Orn
OrnithineOrnithine is a non-essential and non-protein amino acid that participates in detoxifying cells through its important role in the urea cycle. It is useful in strength athletes because of its effect on releasing growth hormone. It is also a precursor of the key amino acid glutamic acid, proline and citrulline.
Pro
ProlineAlthough non essential, the amino acid proline is one of the main components of collagen, the most abundant structural protein in the human body. Proline provides specific sport nutritional benefits including protein synthesis and anti-fatigue properties during exercise.
Se
SeleniumSelenium is an important mineral needed by the body to fulfill several processes. It plays an important role in the normal functioning of the immune system, in the functioning of thyroid gland, and in the production of DNA (the molecule that makes up our genes). Selenium is also involved in protecting the body from infection and has antioxidative properties, which means it protects cells from oxidative damage. Physical sport training increases the bodyâs requirement for selenium. Selenium forms a part of glutathione that provides protective effects against exercise-induced oxidative stress and cell damage. Also, selenium helps recover from overtraining and enhances recovery after intense strength training.
Tau
TaurineTaurine is one of the most abundant amino acids in organs throughout the human body including muscle tissue. Taurine is not used to build proteins, but it has multiple physiological functions important to athletes, including support of the central nervous system, regulation of calcium homeostasis in both skeletal muscle and cardiac tissue, increased muscle force, improved lipid metabolism, and increased insulin sensitivity for improved carbohydrate metabolism and glycogen resynthesis. Taurine has also antioxidant properties, which means that it protects tissues from oxidative damage.
Thr
ThreonineThreonine is one of the essential amino acids, meaning it must be provided by food since the body is not able to synthesize it. Threonine is needed for the production of structural proteins, such as collagen and elastin (components of the skin and connective tissue), and participates in the metabolism of fats. It is therefore particularly important for strength athletes. Low intakes of threonine through the diet have been shown to impair tissue growth and function and reduce skeletal muscle. Threonine also plays a role in immune function.
Trp
TryptophanTryptophan is an essential amino acid required for normal growth and is involved in the formation of protein and neurotransmitter. In the body, tryptophan gets partially converted to serotonin, a neurotransmitter that regulates appetite, sleep, and mood. Tryptophan is also needed for the formation of melatonin, a hormone that regulates the sleepâwake cycle and that has antioxidant properties. Tryptophan deficiency may lead to problems falling asleep, insomnia, anxiety disorders and depression.
Tyr
TyrosineTyrosine is involved in the production of the catecholamine hormones and neurotransmitters, such as dopamine, epinephrine, norepinephrine. It is also known to improve alertness, attention, and focus.
Val
ValineValine is a branched chain amino acid (BCAA) involved in muscle protein synthesis. It is an essential amino acid that helps supply the muscles with glucose for energy production during intense physical activity. It is also involved in nitrogen transport into the muscles and in turn shuttle more oxygen and nutrients for extended performance. A good balance is required because too high levels of valine are known to increase the amount of ammonia in the body and disrupt liver and kidney function.
VitA
Vitamin A RetinolVitamin A exists in two different forms: preformed vitamin A, exclusively occurring in animal products, and provitamin A carotenoids (e.g. beta-carotene) found in vegetal products. In the body, both forms of vitamin A are converted to retinal and retinoic acid, the active forms of vitamin A. Vitamin A plays an essential role in vision (particularly in night vision), skin and mucous membrane health, cell growth, fetal development, and immune function. Beta-carotene has also antioxidant properties, which means it protects cells from oxidative damage. After consumption, most of the vitamin A is stored in your liver for future use.
VitB12
Active vitamin B12Holotranscobalamin (holoTC) is referred to as active vitamin B-12. Vitamin B12, named cobalamin, is required for protein synthesis, for the formation of DNA (the substance that makes up our genes) and the production of red blood cells, which carry oxygen throughout the body. Vitamin B12 also supports brain and nervous system functions. Signs of vitamin B12 deficiency include tiredness, muscles weakness, difficulty concentrating, leg cramps, and nerve problems (e.g. numbness and tingling in the hands and feet), depression. Severe deficiency of vitamin B12 can result in anemia and reduce endurance performance. It may also result in decreased ability to perform high intensity exercise. Vegetarians and vegans are at higher risk of developing vitamin B12 deficiency since this vitamin is mainly found in animal products. Elderly people are also at risk of deficiency since the capacity of vitamin B12 absorption decreases with age.
VitE
Vitamin E Alpha-TocopherolVitamin E plays a role in maintaining optimal immune function and blood viscosity, both factors being important in athletes' ability to train and compete. It also acts as a strong antioxidant in the body, meaning it protects cells against oxidative damage. Vitamin E participates in making red blood cells that carries oxygen throughout the body, plays a role in the interactions between cells, and is needed to keep blood from clotting within blood vessels.
VitD
Total Vitamin DVitamin D is known as the âsunshineâ vitamin as our body can create it from cholesterol when the skin is exposed to sunlight. Vitamin D plays essential roles in the body. It helps to maintain bone growth and the health of bones, teeth, and cartilage since it improves the absorption of calcium and phosphorus. It is required for protein and hormone synthesis and helps the immune system to function appropriately. Vitamin D also regulates the development and homeostasis of the nervous system and skeletal muscle. A common symptom of clinical vitamin D deficiency is muscle weakness.
Ï-3
Omega-3 IndexOmega-3 Index corresponds to the amount of two omega-3 fatty acids, EPA and DHA, in red blood cell membranes, expressed as a percentage of total fatty acids. Omega-3 Index is an indicator of better overall health and a higher Omega-3 Index has among others been associated with decreased risk for cardiovascular diseases.
Zn
ZincZinc is an essential mineral that your body needs for several processes, including normal growth and development, building and repair of muscle tissue, energy production, DNA production (the molecule that makes up our genes), thyroid homeostasis, and skin health. It contributes to the normal function of your immune system (including wound healing), and to normal mental performance (concentration). Since your body cannot store it, you must get zinc from your diet regularly. Zinc deficiency can lead to latent fatigue with decreased endurance, poor wound healing, significant loss in bodyweight, anorexia, and a risk of osteoporosis. Ensuring an adequate zinc status will have a positive impact on your performance and recovery.
T/COR
Testosterone/Cortisol ratioThe testosterone/cortisol ratio is a more specific marker of exercise-induced stress than testosterone or cortisol alone. While abnormal levels in testosterone and in cortisol can be caused by other factors, the testosterone/cortisol ratio is better associated to physiological stress during training, athletic performance and recovery. Although the ratio tracks linearly with training volume in many sports, a too low ratio is detrimental to performance and may be the result of overtraining. This test is only valid in males because testosterone levels are generally too low in females.
Fer
FerritinFerritin level reflects the amount of iron the body has stored for future use. Iron is an important mineral required to transport oxygen in the blood to the tissues and ensures that our muscles are working properly. It also helps the body convert carbohydrates into energy during exercise. It also plays a role in the transmission of nerve impulses, and in the creation of certain hormones. The following symptoms may occur as a result of iron deficiency: weakness, exhaustion, decreased exercise performance, increased heart rate and shortness of breath during exercise, headaches, and dizziness. Slight iron deficiency is not a major concern for a sedentary person but athletes who train for 7 or more hours per week often have iron-deficiency mild anemia that affects performance. Frequent blood donors, vegans and women with heavy menstruations are at higher risk of iron deficiency anemia.
COR
CortisolCortisol is a steroid hormone produced by the adrenal glands that plays an essential role in metabolism of macronutrients. Cortisol also helps the human body to manage stress, notably exercise-induced stress. Normally, cortisol levels rise during the early morning hours and are highest about 7 AM. They drop very low in the evening and during the early phase of sleep.
In athletes, elevated cortisol can be the result of acute muscle breakdown and stress seen with intense exercise or heavy training. Elevated cortisol can be associated with increased physical or emotional stress, strenuous activity, infection or injury. It is important for athletes to prevent chronically elevated cortisol because cortisol has a catabolic effect on tissue (muscle breakdown) and is associated with a decrease in key anabolic (muscle growth) hormones. Although the size of the increased cortisol response to intense exercise lessens with habitual training, overtraining leads to high levels of cortisol detrimental to sport performance.
TT
Total TestosteroneTestosterone is the main male steroid hormone. Testosterone is considered a prime hormonal driver of anabolism (muscle growth). In males, testosterone is mainly produced by the Leydig cells in testes. Although females do also produce the hormone by the ovaries and the adrenal glands, the levels are far lower than in males. This test determines the levels of total testosterone in males. Total testosterone levels in females are generally too low to be measured by this test.
High volume of training and high intensity exercise does decrease testosterone levels. Low testosterone levels in male athletes, scientifically known as Exercise Hypogonadal Male Condition (EHMC), is common in elite athletes and is the result of an adjustment within the hypothalamic-pituitary-testicular axis to exercise. It is important to minimize the decrease in testosterone levels caused by exercise through proper nutrition and modification to training.
