All About L-Leucine Capsules

What is L-Leucine?

• L-Leucine is one of the essential branched-chain amino acids (BCAAs) (along with Isoleucine and Valine).

• It plays a critical role in muscle protein synthesis, energy production, and recovery.

• Since the body cannot make it on its own, it must be obtained from diet or supplements.
