Leucine (L-Leucine)

Leucine, or L-Leucine, is an essential amino acid and one of the three branched-chain amino acids known as BCAAs, together with isoleucine and valine. The body cannot produce leucine on its own, so it must be obtained through food or supplements.

L-Leucine is particularly popular among athletes and physically active people. It is often used alongside protein or other amino acids. Leucine is available as a standalone supplement as well as a component of various BCAA and amino acid complexes.

In this category you can find L-Leucine powders, capsules and other forms. Explore our other amino acids, tyrosine and food supplements for an active lifestyle.
