HIV and Glutamine
Glutamine-antioxidant nutrient supplementation can increase body weight, body cell mass, and intracellular water when compared with placebo in HIV patients.
Glutamine is helpful in HIV patients who are receiving certain types of anti-viral medicines.
Other medical conditions
Glutamine appears be helpful in those with cancer, HIV, or other medical conditions that lead to a catabolic state, but does not seem to play a significant role (by itself) in those who are healthy or provide any significant enhancement in athletic performance.
