Glutamine
Glutamine- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
This supplement has been used in connection with the following health conditions:
Used for Amount Why Pre- and Post-Surgery Health20 grams daily 
[3 stars] Studies have shown that using glutamine-enriched formulas after surgery increased immune cell activity, shortened hospital stays, improved nutritional status, and reduced infections.Athletic Performance and Post-Exercise Infection5 grams after exercise, then again two hours later 
[2 stars] The amino acid glutamine may benefit athlete's immune systems. Double-blind trials giving athletes glutamine reported 81% having no subsequent infection compared with 49% in the placebo group.Diarrhea136 mg per pound of body weight [2 stars] Glutamine appears to be beneficial for diarrhea by improving the health of the intestinal lining, rather than by affecting the immune system.HIV and AIDS Support and Preservation of Lean Body Mass
(Arginine, HMB)1.5 grams of HMB, 7 grams of L-glutamine, and 7 grams of L-arginine twice per day [2 stars] The combination of glutamine, arginine, and HMB may prevent loss of lean body mass in people with AIDS-associated wasting.Immune Function and Post-Exercise InfectionRefer to label instructions [2 stars] A study giving athletes glutamine, an amino acid important for immune system function, reported significantly fewer infections with glutamine.Alcohol Withdrawal
(L-Tyrosine, Multivitamin, Phenylalanine, Tryptophan)Refer to label instructions 
[1 star] In double-blind research, alcoholics treated with L-tyrosine combined with DLPA (D,L-phenylalanine), L-glutamine, prescription L-tryptophan, plus a multivitamin had reduced withdrawal symptoms and decreased stress.
Alcohol WithdrawalRefer to label instructions [1 star] Animal and double-blind human research has shown that this amino acid reduces desire for alcohol and anxiety levels.GastritisRefer to label instructions [1 star] The amino acid glutamine is a main energy source for cells in the stomach and may increase blood flow to this region.HIV and AIDS SupportRefer to label instructions [1 star] The amino acid glutamine is needed for the synthesis of glutathione, an important antioxidant that is frequently depleted in people with HIV and AIDS.Peptic UlcerRefer to label instructions [1 star] Glutamine, an amino acid, is the main energy source for cells that line the small intestine and stomach. Supplementing with it may help people overcome peptic ulcers.Glutamine is the most abundant amino acid (protein building block) in the body and is involved in more metabolic processes than any other amino acid. Glutamine is converted to glucose when more glucose is required by the body as an energy source. It serves as a source of fuel for cells lining the intestines. Without it, these cells waste away. It is also used by white blood cells and is important for immune function.

Comments about GNC Pro Performance® L-Glutamine:
I find that regular use of L-Glutamine means I am in better-than-average overall health, so I take it every day - even on non-workout days. I also find that taking L-Glutamine before and after workouts results in more energy to power through tough routines, and then faster recovery/muscle building afterward.

Comments about GNC Pro Performance® L-Glutamine:
i tried this product a while and i loved it from the start, first off, its a amino acid so theres no side effects or anything, its just like eating 10 stakes all at once. The other thing that caught my eyes was the price, it was a nice [$] price and it was buy one get one free. that was amazing, but anyway, i like this product a lot. i've seen my muscles improve in 2 days. It's a amazing product, and i started to show muscle details and i was starting to get vascular, it is a amazing feeling. Of course theres a catch to everything. There are two bad things about this product, but there VERY minor. the first one is that you are literally drenched in sweat. It makes your body look like u just to a smelly shower, and the second bad thing that happens is that when u swallow the pill, your adams apple hurts a lot, and i have to drink a whole water bottle to make it stop itchoverall, i think this is a good, affordable, healthy product thats worth buying considering there's a buy 1 get 1 sale and its only [$] the pills are not bad to swallow despite the pain, but ill swallow an anchor just to get bigger muscles, also it makes you gain 1 pound per 2-3 days. That i like the most, so if your trying to lose weight, this isn't really the product you would take. I hope my message has inspired you to go out and get the product, you will not regret it
