Take 1 capsule between meals, 1–3 times daily. The most important time is immediately post-workout, when glutamine levels are at their lowest and your body's demand for repair is highest.

Glutamine is the primary fuel for the cells lining your intestinal wall. Hard training — especially in heat — can damage this lining and lead to GI distress. Supplementing with glutamine strengthens the mucosal barrier, helping reduce gut problems during and after exercise.

Research on endurance athletes shows that glutamine levels drop significantly after prolonged exercise, which coincides with immune suppression. Supplementing post-exercise supports healthy immune cell function and has been associated with reduced self-reported illness in marathon and ultra-marathon runners.

Free-form means the glutamine isn't bound to other amino acids, so it's immediately available for your body to absorb and use. This is the most efficient form for supplementation.
