Glutamine Info

1. The extremely popular amino acid L-Glutamine can be found in protein powders, beans, meats, fish, poultry, dairy products, and of course, L-Glutamine supplements

2. 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 body builders.* When supplemented, it may help body builders reduce the amount of muscle deterioration that occurs because other tissues that need glutamine will not rob the glutamine stored in the muscle cells.*

Research suggests that after intensely 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 suggest that glutamine supplementation can minimize the breakdown of muscle tissue and improve protein metabolism.* Glutamine's cell-volumizing effects have also been supported by several studies.* No conclusive studies have been done to evaluate the effects of L-glutamine supplementation on weight-training adults; however, a recent study suggests a meaningful increase in growth-hormone levels when as little as 2 grams of free-form L-glutamine supplement was consumed!*

3. Who needs it and what are some symptoms of deficiency? Bodybuilders can particularly gain from the intake of glutamine. Since bodybuilders use a lot of their glutamine when working out, the immune system relies heavily on this amino acid.*

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.*

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

Reports of an upset stomach are associated with ingesting large quantities of glutamine; using smaller doses is recommended if this occurs. Always consult the manufacturer's labeling for instructions on proper supplement dosage.

Note: Glutamine peptides are different than regular L-glutamine.

Glutamine (abbreviated as Gln or Q) is one of the 20 amino acids encoded by the standard genetic code. Its side-chain is an amide formed by replacing the side-chain hydroxyl of glutamic acid with an amine functional group. Therefore, it can be considered the amide of glutamic acid. Its codons are CAA and CAG. In human blood, glutamine is the most abundant free amino acid, with a concentration of about 500-900 µmol/l. Functions
Glutamine plays a role in a variety of biochemical functions including:

Protein synthesis, as any other amino acid. Regulation of acid-base balance in the kidney by producing ammonium.
Cellular energy, as a source, next to glucose.
Nitrogen donation for many anabolic processes.
Carbon donation, as a source, refilling the citric acid cycle.
Producing and consuming organs
Producers Glutamine is synthesized by the enzyme glutamine synthetase from glutamate and ammonia. The most relevant glutamine-producing tissue is the muscle mass, accounting for about 90% of all glutamine synthesized. Glutamine is also released, in small amounts, by the lung and the brain. Although the liver is capable of relevant glutamine synthesis, its role in glutamine metabolism is more regulatory than producing, since the liver takes up large amounts of glutamine derived from the gut.

The most eager consumers of glutamine are the cells of intestines, the kidney cells for the acid base balance, activated immune cells and many cancer cells. In respect to the last point mentioned, different glutamine analogues such as DON, Azaserine or Acivicin are tested as anti-cancer drugs.

Examples for the usage of glutamine In catabolic states of injury and illness, glutamine becomes conditionally-essential (requiring intake from food or supplements). Glutamine has been studied extensively over the past 10–15 years and has been shown to be useful in treatment of serious illnesses, injury, trauma, burns, and treatment-related side-effects of cancer as well as in wound healing for postoperative patients.
Glutamine is also marketed as a supplement used for muscle growth in weightlifting, bodybuilding, endurance, and other sports, Evidence indicates that glutamine when orally loaded may increase plasma HGH levels by stimulating the anterior pitutitary gland. In biological research, L-glutamine is commonly added to the media in cell culture.

Aiding recovery after surgery It is also known that glutamine has various effects in reducing healing time after operations. Hospital-stay times after abdominal surgery can be reduced by providing parenteral nutrition regimes containing high amounts of glutamine to patients. Clinical trials have revealed that patients on supplementation regimes containing glutamine have improved nitrogen balances, generation of cysteinyl-leukotrienes from polymorphonuclear neutrophil granulocytes, and improved lymphocyte recovery and intestinal permeability (in postoperative patients), in comparison to those that had no glutamine within their dietary regime, all without any side-effects.

Nutrition Occurrences in nature
Glutamine is the most abundant naturally occurring, non-essential amino acid in the human body and one of the few amino acids that directly cross the blood-brain barrier. In the body, it is found circulating in the blood as well as stored in the skeletal muscles. It becomes conditionally essential (requiring intake from food or supplements) in states of illness or injury.

Dietary sources Dietary sources of L-glutamine include beef, chicken, fish, eggs, milk, dairy products, wheat, cabbage, beets, beans, spinach, and parsley. Small amounts of free L-glutamine are also found in vegetable juices and fermented foods, such as miso.

Aiding gastrointestinal function

In recent studies, glutamine-enriched diets have been linked with intestinal effects including maintenance of gut barrier function and cell differentiation. This may relate to the fact that the intestinal extraction rate of glutamine is higher than that for other amino acids, and is therefore thought to be the most viable option when attempting to alleviate conditions relating to the gastrointestinal tract. These conditions were discovered within the gut between glutamine-enriched and non-glutamine-enriched diets. However, even though glutamine is thought to have "cleansing" properties and effects, it is unknown to what extent glutamine has clinical benefits, due to the varied concentrations of glutamine in varieties of food. - Сайт и форум о фитнесе и бодибилдинге!
