General information
Branched-chain amino acids (BCAAs) are a subcategory of the essential amino acids (EAAs) and are vital to the human organism. BCAAs consist of L-Leucine, L-Isoleucine and L-Valine and are applied in most of the popular supplements for athletes.
Characteristics of BCAAs :
BCAAs, particularly L-Leucine, stimulate synthesis of muscle protein and muscle growth like no other amino acids once they penetrate into the blood stream. This effect is amplified by the secretion of anabolic hormones such as insulin. On a hormonal level, supplementing with BCAAs or BCAA Formulas improves the ratio of cortisol (catabolic) a negator of testosterone (anabolic) and secretion of growth hormones. If saturation of BCAAs has reached a high level, they may be converted into other important amino acids such as glutamine and overall they work against muscle degradation.
These characteristics also improve training, endurance exercise and well-being, since they limit the penetration of fatigue transmitters and work as energy substrates. Plus BCAAs work as fat burners, by supporting a particularly persistent, so called “brown fat”. They are therefore great for all sports and diets.
