Product Description
L-Leucine is an essential branched-chain amino acid (BCAA) critical for protein synthesis, muscle repair, and metabolic regulation. As one of the three BCAAs (alongside isoleucine and valine), it cannot be synthesized by the human body and must be obtained through diet or supplementation. L-Leucine is commercially produced via microbial fermentation or enzymatic hydrolysis, ensuring high purity (>98%) and compliance with Food Grade, Pharmaceutical Grade, USP/EP, and Halal/Kosher standards.
Key Features
Anti-Catabolic Effect: Reduces muscle breakdown during fasting or intense exercise.
Energy Source: Oxidized in skeletal muscle to provide energy during prolonged activity.
High Solubility: Easily dissolves in water, suitable for beverages, powders, and tablets.
