Platinum 100% Glutamine features L-glutamine (2,5-diamino-5-oxopentanoic acid) ? the most abundant amino acid found in our blood. Increased glutamine content in muscle allows glutamine to suppress the oxidation (breakdown) of the branched-chain amino acid leucine ? the key amino acid involved in protein synthesis. Since hard training can deplete glutamine stores, supplementing with high-quality glutamine can help replenish these glutamine levels. Not recommended for pregnant/lactating/children/under 18 yrs.
