L-Leucine is the most important amino acid of BCAA, which supports protein synthesis, protects muscle mass and dramatically improves regeneration

L-Leucine is an essential amino acid, which is one of the three amino acids with branched BCAA chain (Leucine, isoleucine, and Valine). Of these three amino acids, Leucine stands out the most because it is the most efficient activator of protein known as mTOR [1] (its activation is able to positively influence the synthesis of muscle protein), and it is also exclusively ketogenic amino acid (produces ketones in metabolization)[2] [3]

This amino acid is the most involved in the growth of muscle mass [4], however it is used the most in aerobic or anaerobic sports. [5] During an endurance or strength effort, Leucine is used as a kind of luxury fuel. Therefore, it is necessary to replenish in the diet or in the form of food supplements. In addition, you must have enough L-Leucine in proportion to other amino acids, so that your body can take full advantage of all the nutrients of all the food you eat. If you do not have enough L-Leucine, your body will not be able to use the proteins [6], which are provided, regardless of the amount consumed. Levels of Leucine indicate the rate of anabolism in the body and accelerates the regeneration and prevents the loss of muscle tissue, like in case of slimming diets.
