The dosage regimen may vary depending on the kind of exercise, its length and weight of the person using this supplement. To simplify, it's assumed that the optimum dosage of BCAA is 10g per day. It's best to take in two separate dosages: before workout (around 30 minutes) and after workout (even immediately), approximately 1g/10kg of body mass. On rest days it's recommended to use BCAA on an empty stomach and before going to bed. People who are trying to reduce fat tissue can adapt a similar dosage regimen as athletes. In the absence of contraindications, BCAA amino acids can be used daily.
BCAA are three essential amino acids having a side branched aliphatic chain (isoleucine, leucine, and valine) and a similar course of metabolic processes, occurring in the muscle tissue. In its natural form, they are found in high-protein animal foods (i.e. beef, milk proteins). BCAA have the anti-catabolic and anabolic potential. They support energy carriers during the energy crisis and affect the functioning of the nervous system (eliminate stress, reduce fatigue), hormone activity and kinases, which are responsible for the metabolism of proteins. In the sports supplementation they are used as supporting elements of exercise capacity (strength and endurance) and post-workout recovery; also as anti-catabolic and catalyst of anabolic changes. Taking BCAA after exercise almost immediately restores the levels of these amino acids in the blood (excluding liver) and supplies the muscle tissue. Leucine activates of mTOR kinases (starting anabolism of muscle proteins) and has the intensified effect with insulin, which acts on the PI3-kinase and protein kinase B. Branched amino acids chain BCAA, willingly used by strength, strength-endurance and endurance athletes, they are available in the form of single-component supplements, and advanced amino acid supplements, creatine, pre- and post- training stacks, and isotonic drinks.
Dosage: usually 1-2 grams of BCAA per 10 kg of body weight per day. Mainly before and after training.
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.
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.
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.).
