MuscleTech Platinum 100% Glutamine provides pure glutamine powder to help replenish levels after intense and prolonged exercise. Glutamine is the most abundant amino acid in the body with high concentrations in the muscles. Exercise can often deplete glutamine levels – up to 50% so it’s important to replace it as soon as possible. Lowered glutamine levels can wreak havoc on your immune system and leave your body more prone to becoming sick. Glutamine also helps to provide nitrogen as a way to support muscle building and can also increase cell volume, replenish glycogen and support overall protein synthesis. Muscletech’s Platinum 100% Glutamine is stimulant free, making it an ideal supplement to use day and night to help support your gains.
