During times of physical stress & exertion glutamine reserves can be depleted. Glutamine's role in the body is critical to peak performance. As the most abundant amino acid in muscle tissue, glutamine has a positive protein-sparing role in protein synthesis & immune system enhancement. Glutamine supplementation can influence muscle tissue recovery, supporting gains in growth & strength while enhancing immune function. Glutamine can be taken with water or added to protein powders & meal replacements to ensure adequate levels.IMPROVE MUSCLE RECOVERY & SUPPORT ANABOLISM*MINIMIZED MUSCLE CATABOLISM (BREAKDOWN)*INCREASE MUSCLE CELL VOLUME*SUPPORT A HEALTHY IMMUNE SYSTEM*
