Ultra-pure micronized glutamine. HPLC-tested pure glutamine, replenish plasma glutamine. Platinum 100% Glutamine supplies 5g of glutamine per serving, which works to rapidly replenish the glutamine used during training. Glutamine is the most abundant non-essential free amino acid in your body- more than 20% of the total circulating amino acids in your body are glutamin. Your muscles are especially high in glutamine, making it extremely important for muscle metabolism. When you're training hard, your muscles can lose up to 50% of their glutamine stores, so you need to replenish them- fast! Glutamine helps your body control catabolism by acting as a free nitrogen donor to help your muscles build the other amino acids they need to recover quickly. Glutamine also helps support increased cell volume, glycogen replenishment, and protein synthesis. Platinum 100% Glutamine is perfectly tasteless and odorless, and mixes effortlessly on its own or into any other product you're already using. This non-stimulant formula stacks perfectly and can be used day or night
