Glutamine Peptides, and you (in regards to Anabolism, and Muscle Maintenance)


Community Veteran
Hi guys as we all know the market is littered with a variety of supps that either do not work, or are not very good,
some stars do exist though.

Most of us agree that creatine is a viable supp, as well as Alpha Lipoic Acid, and a handful of Great protien Powders out there.

Glutamine for all intent and purposes was suppost to be the next star yet upon consumer testing, the response has been fair, not great but fair.......some are loyal, and some says it mostly crap.

I would side with those who say most of it is crap............however we have a new dynamic to deal with in regards to the efficacy of Glutamine as an additive to our great Supps list, and that dynamic is the advent of Stable Glutamine Peptides.

here is some info.

The Benifits of Glutamine Peptides

Glutamine peptides are a natural source of glutamine produced by a proprietary process using protein and food grade enzymes. It provides protection during metabolic stress conditions, such as exercise, by protecting the cell’s ability to make and regulate energy. Cells and tissues can be damaged by oxidative and other stress conditions where the normal process of cell energy metabolism is disrupted. These injuries impair performance and slow recovery.

Glutamine peptides offer several advantages over free form glutamine including better nitrogen retention and protein synthesis. A natural source of glutamine, derived from 100% protein, peptides have better absorption characteristics. Glutamine peptides contain additional peptide fractions not available in pure L-glutamine products making it stable in a solution because it contains bound glutamine. It has a higher solubility and heat stability over a wide temperature range. This allows the peptide bonded glutamine to be acid and heat stable so cooking and/or acidic beverages will not destroy the glutamine.

Lastly, glutamine peptides have the antioxidant action similar to 3-5 servings of fruit or vegetables based on ORAC (oxygen radical absorbance capacity) for vitamins C, E, and beta-carotene. Glutamine peptides offer 300 times more ORAC antioxidant equivalents as compared to free glutamine.


Vitamin E (500mg) 116
Vitamin C (500mg) 2830
3-5 servings of fruits and vegetables 1950
B-carotene (250mg) 300
Free amino acid glutamine (5-7g) 3.5-5.4
Protein hydrolysate (10-15g) 1100-1650

The following is one of many studies

Glutamine Peptides to Prevent Protein Loss After Surgery

Conditions of catabolic stress, such as surgery, trauma or infection, lead to nitrogen loss. This loss is believed to come from muscle protein breakdown, which leads to the transport of glutamine to visceral organs, resulting in profound intramuscular glutamine depletion. Since muscle glutamine concentration strongly correlates with the rate of protein synthesis, and since glutamine is known to promote protein anabolic processes, parenteral nutrition supplementation with glutamine would likely conserve protein and promote healing. Unfortunately, glutamine is too unstable to be added directly to infusion solutions; however, this drawback can be overcome by substituting short-chain peptides, which are hydrolyzed by the body to free amino acids.

Stehle and colleagues tested the efficacy of glutamine supplementation in a study of 12 patients recovering from resection of carcinoma of the rectum or colon. Synthetic dipeptide containing alanine and glutamine was added to the parenteral nutrition of six of the patients. The other six patients, who served as a control group, received similar parenteral nutrition and supplementation with a dipeptide containing alanine and glycine. Daily nitrogen balance was calculated for each patient, and muscle biopsies were performed immediately before surgery and on the third postoperative day.

The mean daily nitrogen balance of the patients who received glutamine supplementation was significantly higher than that of patients in the control group. During the five days of the study, the patients who received glutamine lost the equivalent of 9g of protein daily compared with a loss of 23g daily in the control group. The authors estimate that supplementation with glutamine resulted in a total savings of 300g of muscle mass for each patient who received it. (Lancet, February 4, 1989, vol. 1, no. 8632, p. 231.)


Even though the body does produce glutamine endogenously.

When the body goes through trauma from calorie restriction or physical damage (whether this restriction or damage is from diet, exercise, or stress)

the body depletes glutamine reserves, by literally draining your viceral organs, and muscles of it.

the process of depletion, and the subsequent replenishing of those reserves by our own bodies creates several windows of opportunity to occur for catabolism ( muscle loss) , and immune sytem suppression.

Exogenous Glutamine injestion especially from a superior form that is bioavailabe and thus stable throughout the process of digestion through the GI the glutamine needed to stave of the catabolic stresses of diet, exercise, or illness.

Since muscle growth and maintainence is strongly correlated to the amount of glutamine present in the body.

Extra exogenous injestion form Glutamine Peptides stops the body from losing muscle under tremendous stress, and if taken under little stress you build muscle...........

also Glutamine in this form when taken with carbs post workout signifigantly speeds up glycogen replensihment bar non.....

and recovery from workouts are alot faster........
