Leucine

Leucine: what it is and what it is for

Leucine is an essential branched-chain amino acid and, together with isoleucine and valine, it is part of the BCAA. As an essential amino acid, it cannot be produced by the body and must be obtained through diet or supplementation. It is one of the most studied and appreciated amino acids among people who play sports.

The role of leucine

Leucine is involved in processes related to protein metabolism and is one of the most present amino acids in BCAA formulations, where it appears in a higher proportion than isoleucine and valine (for example in 2:1:1, 4:1:1 and 8:1:1 ratios). For this reason it is often considered a reference point in branched-chain amino acid blends.

When to take leucine

Leucine, available in powder and capsules, is generally taken around training time or combined with other amino acids and proteins. The methods and amounts may vary depending on your goals and diet.
