Sport Rx 100% Pure L-Glutamine 200g

Glutamine is a powerfully beneficial amino acid, being the most abundant amino acid in muscle cells. With extremely hard training, intra-muscular glutamine levels can drop. When this happens, muscle cell volume decreases, resulting in muscle catabolism (muscle loss). As glutamine plays a role in immune responses, falling levels can partially explain the increased susceptibility of hard-training athletes to infections.
