Muscletech Platinum 100% Glutamine Powder Unflavoured When you’re training hard, your powers can lose up to 50% of their glutamine stores, so you need to replace them. This powder supplies 5g of L-glutamine per serving, which works to replenish the L-glutamine used during training. Glutamine rapidly is the most abundant non-essential free amino acid in your body, and your muscles are exceptionally high in glutamine, making it extremely important for muscle metabolism.
