Glutamine Research and Information


The insanely popular conditionally essential amino acid L-Glutamine can be found in protein powders, beans, meats, fish, poultry, dairy products, and of course, L-Glutamine supplements from A1Supplements.com.

What does it do and what scientific studies give evidence to support this?

Glutamine is highly in demand throughout the body. It is used in the gut and immune system extensively to maintain optimal performance. 60% of free-form amino acids floating in skeletal muscles is L-glutamine. L-glutamine plays a very important role in protein metabolism, and it appears to be a very important nutrient for fitness enthusiasts. When supplemented, it may help to reduce the amount of muscle deterioration that occurs because other tissues that need glutamine will not rob the glutamine stored in the muscle cells. Its use is popular as an accelerated recovery aide.

Research shows that after working out, glutamine levels in the body are reduced by as much as 50%. Since the body relies on glutamine as cellular fuel for the immune system, scientific studies have shown that glutamine supplementation can minimize the breakdown of muscle tissue and improve protein metabolism.

Its effects on replenishing the body after stress or trauma have been shown in Europe where it is commonly given to patients in hospitals. Glutamine's cell-volumizing effects have also been shown in several studies. No conclusive studies have been done to evaluate the effects of L-glutamine supplementation on weight-training adults; however, a recent study showed up to a 400% increase in growth-hormone levels when as little as 2 grams of free-form L-glutamine supplement was consumed!

Who needs it and what are some symptoms of deficiency?

anyone who works our regularly with weights can particularly gain from the intake of glutamine.

Catabolism or muscle break down can occur if the body robs muscles of glutamine for use elsewhere such as nitrogen transport or maintaining the immune system. Glutamine supplementation is certainly important in keeping muscles building--not deteriorating.

How much should be taken? Are there any side effects?

Athletes and fitness enthusiasts can benefit by taking ten grams of L-glutamine per day, although clinical studies have not determined a precise amount for muscle metabolism optimization.

There are no side effects associated with L-glutamine, because it is a nutrient naturally occurring in the body. Reports of an upset stomach are associated with ingesting a great deal of glutamine, using smaller doses is recommended if this occurs.
