L-Glutamine Powder

Glutamine is a building block of glutathione, a powerful antioxidant made by the body to protect cells from pathogens and toxins. This makes glutamine an important nutrient for the immune system.

Glutamine is also a critical nutrient for immune cells and enterocytes—the cells that line the digestive system. Although glutamine is found in high-protein foods, efficient digestion is required to liberate it from food. So if you’re afflicted by food intolerances, irritable bowel syndrome, ‘leaky gut’, inflammatory bowel disease or other digestive conditions involving compromised absorption, a supplement can provide you with a readily absorbed form of glutamine because it requires no digestion.

Physical stress uses up glutamine at a rapid rate. Prolonged strenuous exercise, infections, burns, surgery, bowel disease and immune-compromised conditions are all examples of situations that can deplete your blood’s glutamine levels. By supporting muscle cell repair and glycogen replenishment, supplementary glutamine can benefit individuals with exercise-related muscle soreness, enabling you to take shorter rest periods between intense workouts by quickly restoring blood glutamine levels.
