About this product

L-Glutamine is the most abundant amino acid in the bloodstream and the primary fuel source for two of the body's most rapidly dividing cell populations: enterocytes (the cells lining the small intestine) and immune cells. Under normal conditions, the body produces enough glutamine to meet demand. But during prolonged stress, intense endurance training, injury recovery, or compromised gut barrier function, glutamine becomes 'conditionally essential.' Supplementation may support gut barrier integrity, immune resilience after hard training, and recovery from physical stressors. Standard doses are 5-10 g per day, mixed in water or a non-acidic beverage on an empty stomach.

WHY L-GLUTAMINE POWDER MATTERS

The primary fuel for intestinal cells and immune cells. Useful during high stress, intense training, or gut barrier issues.
