Leucine is part of the BCAA branched-chain essential
amino acid group, which stands out for its oxidation
rate higher than valine and isoleucine.
As our body does not produce it, it can be found and
ingested through foods such as fish, meat, milk, and
egg, among others, and supplements with the amino acid
isolated or in whey protein and BCAA.
Of all, leucine is one of the most important, and that's
because it is part of a group known as essential amino
acids. These substances are even more special precisely
because they cannot be produced by the body itself,
which means they are obtained through food or
Along with other amino acids, valine and isoleucine, it
forms a branched chain known to athletes: BCAA. It
favours the construction and growth of muscles and is
essential to obtain good results in training.
