L-Glutamine

L-Glutamine is the most abundant amino acid in the body. It is found in high-protein foods - fish, beans, meat and dairy products and research shows that L-Glutamine helps facilitate the release of growth hormone.

Glutamine Research Highlights

A study by Castell (2001)^[1] showed that in clinical situations and during high-intensity exercise, L-Glutamine decreases the incidence of infections, and a study by Khogali et al. (2002)^[2] indicates that glutamine may be beneficial for patients with coronary heart disease.

Two grams of glutamine get the job done

These studies by Castell (2001)^[1] and Khogali et al. (2002) follow earlier research findings by Welbourne (1995)^[3] that two grams of glutamine will significantly increase HGH growth hormone. Many protein recovery drinks sold today contain up to five grams of glutamine - so two grams may be considered a small dose.

What does this mean to you?

High-intensity training reduces the body's glutamine supply, which must be replaced.

The pre-workout strategy of filling up the glutamine fuel tank before training may do much more than replenish a nutrient used during exercise. Glutamine may help facilitate the release of HGH during training.

L-Glutamine is a powerful supplement with many benefits, but drug interactions with glutamine and chemotherapy forms can occur. Always check the possible side effects of supplements with your doctor.
