Klaire Labs L-Glutamine is a conditionally essential amino acid and a primary energy source for intestinal cells. Glutamine is stored in muscles and is the main metabolic fuel for cells of the small intestine, fibroblasts and the immune system. Glutamine supplementation contributes to the proper proliferation of intestinal mucosa cells and their integrity, resulting in decreased intestinal permeability and systemic infections. L-glutamine is used by athletes to improve immune function, considerably reducing the possibility of developing infections in the upper respiratory tract, and for the maintenance of muscle protein levels during intensive training periods, which prevents the appearance of fatigue, promotes the recovery of muscle fibers and reduces the appearance of injuries. It is recommended to take up to 4 times a day between meals or as directed by a health professional. Food supplements should not be used as a substitute for a balanced and varied diet and a healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of young children.
