Leucine is an essential amino acid, one of the three branched chain amino acids, ketogenic, its isomer is isoleucine. It affects the secretion of anabolic hormones (insulin, combined carbohydrates), acts on enzymes (mTOR) starting the process of muscle protein synthesis and controlling its course. Protein synthesis by leucine is affecting the development of bones, muscles and skin. It reduces the fat tissue. Without the availability of leucine, protein synthesis is impossible. It naturally occurs in animal products (such as eggs, meat, dairy and fish), plant origin, and as a post-training supplements, BCAA, EAA, no-boosters, creatine stacks, carbohydrate supplements. Ir is also in the form of mono-preparation supplements. It is one of the most important amino acids for the athlete's body, basically in every sports discipline.
Dosage: The demand is 5-10 g / 24h, dosage pre- and post-workout and in the morning after waking up.




Lysine belongs to the group of 9 essential amino acids delivered into the body from outside (with food or as a supplement) .It is a building substance of protein (the muscle protein). It is available in food of animal origin (meat, dairy products) and vegetable (legumes). It plays an important role in many physiological processes (absorption of calcium, production of enzymes, hormones and antibodies), and arginine is a component of supplements that increase the synthesis of growth hormone (HGH stimulators). In the form of hydroxylysine (a component of collagen) recommended for the treatment of sports injuries, and prevention. In the case of stress and excessive physical and psychological overloads, it is recommended due to the function of lowering cortisol levels. Also it applies in medicine, in the treatment of anxiety and herpes. The share of lysine intake of daily doses of amino acids should not exceed 5.1%. Available for purchase at
In the processes of digestion of protein matter, as a result of decarboxylation of lysine, may be converted into cadaverine (biogenic amine) having a strong toxicity.
Dosage: the lack of a well-defined standard daily intake of lysine. The supplementation dosages regularly used: with arginine 500 mg - 2g (before bedtime) pre- and post-workout optionally with other amino acids.



Exogenous methionine is an amino acid containing sulphur in its composition. It provides multi metabolism, with the indispensable help of vitamin B6. Participates in the synthesis of phospholipids (e.g. Lecithin), carnitine responsible for transport in the body of long-chain fatty acids, burned in the mitochondria cells (organelles in cells with a separate kernel), along with cystine forms cysteine. It is in the body antioxidant function. Natural source of acquisition of methionine are high-protein foods of animal origin (eggs, meat, fish), vegetable (sesame seeds, grain products). Available in all protein and carbohydrate protein and amino acid supplements such EAA and contain so-called all-day amino acids, supporting the liver preparations and cosmetics supporting the growth and condition of hair, skin and nails.




Alanine is an endogenous amino acid (i.e. having the ability to synthesize the human body other amino acids and pyruvate), building up protein. It has a key role in the transport of nitrogen between the muscles and the liver (i.e. Cahill cycle). It allows to transform glucose in non-sugar compounds. During prolonged exercise it enhances metabolism. It occurs in products of animal origin (meat, dairy, eggs) and vegetable origins (legumes, peas). It is used in the form of amino acid supplements in pre- and post-workout preparations. It complements the BCAA. Increased use of supplements with alanine is required in athletic training when high strength and endurance is required (e.g. weights lifting athletes marathon runners etc.).




Threonine - essential amino acid, or synthesized from food or (and) in the form of supplements. It takes part in the production of new muscle proteins. It is essential for the proper formation of the immune system is maintained in good condition the skin, bones. It affects the normal development of the enamel of teeth and the digestive system by acting positively on the liver and gastric mucosa. It is essential to the proper functioning of the nervous system. On the Polish there are no threonine mono-preparations. Available in the form of blends of amino acids (e.g.the type of EAA) and natural protein supplements.
Deficiency of threonine can cause neurological disorders and increased depression.
Dosage: the lack of standards of daily demand threonine. Doses customarily used in the supplementation.



Tryptophan is one of the nine essential amino acids that require high protein food consumption, mono-preparation supplements tryptophan, an amino acid type and EAA-day nutrients and protein, which is essential in the process of protein synthesis. A derivative of 5-HTP in the decarboxylation is a precursor of serotonin ((tissue hormone having an effect on blood pressure and peristalsis), and the subsequent processes of melatonin (the hormone sleep). It is used for synthesis of nicotinic acid (niacin, known as vitamin PP). The due to the appetite suppressant is also used in certain weight loss formulations.
Even a small deficiency is dangerous for the course of many physiological processes, can cause the nervous system deterioration of mood, insomnia, and disturbances in the digestive process. Tryptophan deficiency in the long term leads to depression and neurological disorders.
Mono-preparation supplements of tryptophan are recommended as a means of reducing the stress and reducing the feeling of insomnia. A part of the nutritional supplements type of EAA and all-day aminoacids, it is a valuable component of protein supplements. Available in store
Doses recommended in supplementation: 500 - 2000 mg at bedtime, alternatively 500 - 1000 mg before meals.



Valine – is a branched essential amino acid, indispensible for the functioning of the nervous system (receiving of sensory information), involved in muscle protein synthesis and energy generation. Administration of additional doses of valine before exercise (or immediately after) has anti-catabolic effect, protecting the proteins and allowing them to rebuild. It is slightly stimulatory (delays symptoms of fatigue during workout), affecting the level and relations of neurotransmitters. It helps to protect the liver. It stimulates an increase in strength and muscle mass, participates in the reduction of body fat. BCAA, EAA, and other mixtures of amino acid supplementation, protein and protein supplements and carbohydrate-stacks, brings positive results in strength and endurance sports.
Valine deficiency can occur in case of increased energy needs of the body,
as the result of stress and too much stress load.


Vitamin B1 (thiamine)


Vitamin B1 (thiamin, vitamin B) improves mental alertness and strengthens the nervous system ensuring the proper functioning of the brain. It improves cardiac and muscular system. It is suportive in the treatment of shingles. Involved in the metabolism of carbohydrates and fats. Natural source of vitamin B1 are brown bread, yeast, eggs, raw vegetables, meat, milk, legumes, cheese.
Vitamin B1 deficiency hinders the processes of decomposition of sugars (catabolism), causes a loss of appetite and disorders in the functioning of the digestive tract, can cause polyneuritis and disease beriberi.
Dosage: Recommended daily intake is 1-2 mg.


Vitamin B2 (Riboflavin)


Vitamin B2 (riboflavin) is soluble in liquids, is involved in the metabolism of proteins, fats and carbohydrates. Required for growth of the organism. Takes part in the production of erythrocytes (red blood cells). It is located in natural foods, such as yeast, meat (especially liver, kidney, heart), milk, fish and green leafy vegetables.
A deficiency of vitamin B2 inhibits the growth, diseases of the mouth, loss and greasy hair, seborrhea and stratification of nails. Increases skin roughness and
susceptibility to acne and oily skin.
Dosage: 1-2 mg per day.


Vitamin B6


Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine) is soluble in the liquid. It participates in the metabolism of proteins, fats and carbohydrates. By reducing the amount of fat in the blood do not enable deposition of the body. It helps the absorption of magnesium and vitamin B12 (cobalamin). It works on the muscle antispasmodic and anti-inflammatory pain in the joints. It acts anti. It provides efficient operation of the brain. It increases energy increasing vigor of a man. The demand for vitamin B6 increases during pregnancy and breast-feeding infants. The natural product is: yeast, eggs, wheat germ, meat (liver), wheat bran, nuts, peanuts peanuts, soybeans. There is a hypothesis that can be synthesized by intestinal bacteria.
Deficiency of vitamin B6 causes abnormal metabolism of proteins, decrease in lymphocytes in the blood, causes a feeling of lethargy and fatigue intensifies.
Dosage: 1.5-2.5 mg daily (increased demand during pregnancy and lactation).




Biotin (vitamin H, co-enzyme R) is in a group of B vitamins, due to the presence of sulphur compounds it is involved in the synthesis of ascorbic acid (vitamin C). Also synthesized in the intestines. It enhances the production of hormones and regulates cholesterol levels. It reduces muscle pain. It prevents hair loss and graying of hair. It soothes the skin inflammations. No toxic effects. Often combined with other B group vitamins and vitamin A. The natural sources of biotin are: whole grain bread, yeast, eggs (yolk), milk, brown rice and cheese.

Daily demand: 100-300 mg per day


Folic acid


Folic acid - also known as vitamin B9, is a synthetic form of naturally occurring folates. It needs to be transformed to folates in order to be biologically active also in the human organism. Therefore, its supplementation is recommended to people who do not have problems with methylation processes.

The majority of people associate folic acid with the period of pregnancy. It is definitely a justified association. Proper supply of vitamin B9 conditions correct development of the fetus and prevents disorders of neural tube defects in a baby.

Supplementation with folic acid also demonstrates positive influence on the functions of the nervous system of adults. Some sources say that it is conducive to maintaining beneficial emotional states. Moreover, folic acid takes part in the process of erythropoiesis, thanks to which it enables efficient production of red cells.

Supplementation with folic acid should be also considered by men who deal with low sperm quality. It was proven that complementing the level of vitamin B9 is conducive to increasing reproductive abilities of men.
