Health Notes

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 AmountWhy
Pre- and Post-Surgery Health
20 grams daily3 stars[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 Infection
5 grams after exercise, then again two hours later2 stars[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.
Diarrhea
136 mg per pound of body weight2 stars[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 day2 stars[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 Infection
Refer to label instructions 2 stars[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[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 Withdrawal
Refer to label instructions 1 star[1 star]
Animal and double-blind human research has shown that this amino acid reduces desire for alcohol and anxiety levels.
Gastritis
Refer to label instructions 1 star[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 Support
Refer to label instructions 1 star[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 Ulcer
Refer to label instructions 1 star[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.

    It's a great product that greatly helps your immune system. I'd suggest mixing with juice as it doesn't mix too well with water.

          This product is really great and I have seen a noticeable difference in muscle growth and recovery time. I mix one spoonful with my whey protein and make a shake. The only complaint I have is that even though it says unflavored, it has a slight bitter taste like if you chew an aspirin. Other than that this product is great!

              Comments about GNC Pro Performance® L-Glutamine Powder:

              Extremely effective against muscle fatigue and that "rusty" feeling after a hard workout from the day before. It considerably speeds up my muscle recouperation and I feel much less lactic acid pain than I would normally if I didn't take the product. Every time I work out hard I take this. Very good product.

                Comments about GNC Pro Performance® L-Glutamine Powder:

                I take about 3 grams 2x/day in my post-workout shakes. At night, I take 5 grams on an empty stomach (no food for at least 2 hours.

                One of the main benefits of L-Glutamine on an empty stomach is that it has been shown to increase HgH levels by 400%.

                It works for me. I am 47, and I am in the best shape of my life.

                      I have found that this product helps me recover from my workouts more quickly for an affordable price. I usually take the product twice, immediately after each of my two daily workouts. If I work out once in a day, I take it after the workout and about an hour before bedtime.

                      Mixes well with protein powders or can just be taken with water.
