NutraBio Pure L-Leucine Powder for Muscle Recovery & Growth - Unflavored Amino Acid Supplement for Athletes & Bodybuilders - Pre & Post Workout, Protein Shakes, Smoothies

L-Leucine is an essential amino acid, meaning it cannot be made by the body, and must be acquired through food or dietary supplements. Leucine is classified as a branched-chain amino acid (BCAA). It comprises about 8% of the total amino acid count in your body's protein structures and is the fourth most concentrated amino acid in skeletal muscle tissue.

L-Leucine stimulates muscle protein synthesis and may be the major fuel involved in anabolic (tissue building) reactions. This makes them especially important for body builders and other athletes in sports that demand explosive strength.
