Leucine is naturally present in BCAA, EAA and protein powders.

Leucine (L-Leucine) is highly regarded as one of the most important essential amino acids. Leucine powder is an easy, convenient and effective way to increase Leucine intake, a main component of branched chain amino acids. L-Leucine is an essential amino acid, meaning we must source it from nutrition or supplement sources as our body is unable to produce it. It is also one of the three branched chain amino acids (BCAA) alongside Isoleucine and Valine. It is the most effective amino acid in BCAA.
