L-Leucine, 1g

Leucine ((S)-Leucine, Leu) is one of nine essential amino acids in humans which is important for protein synthesis and many metabolic functions. It contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway.
