The OstroVit L-Leucine powder contains only L-leucine, an organic chemical compound from the group of exogenous protein amino acids that build muscles. It is the most important of the three branched-chain amino acids that make up the BCAA supplement.

L-leucine is essential as the body cannot synthesize it on its own. Supplementing with L-Leucine powder contributes to body function and muscle tissue development.

L-leucine:

• Stimulates protein synthesis.
• Prevents their breakdown.
• Has a strong anabolic effect.
• Activates the mTOR kinase, responsible for increasing strength and muscle mass.
