Best Glutamine Supplements: Top 10 Glutamine Brands Reviewed

Glutamine is the most abundant amino acid in the body, and as such, it is rarely sufficient. The huge number of processes where it is involved in often make the body confront compromises were to take glutamine from for a certain metabolic pathway. L-glutamine, or briefly - glutamine, is a nonessential amino acid is, as it is synthesized from various organs in the body - the voluntary muscles, the liver, and others.

It is an amino acid that occurs in the greatest amount in the blood plasma - 30-35% and contains about 20% hydrogen in its structure, which makes it the basic carrier of hydrogen for the muscle cells.

Glutamine increases the secretion of the growth hormone and plays an important role in protein metabolism. Studies have shown that after a hard workout the levels of glutamine in the body drop to 50%. Therefore it is best to be taken after training.

When taken regularly, Glutamine protects the muscles from traumatic rupture. The regular adoption ensures that the muscle tissue has a sufficient amount of development.

In the brain, it is a source for the construction of glutamate and it "scums off" the excess ammonia. Glutamine is a component of glutathione - the most powerful antioxidant in the body.

What Is Glutamine

L-glutamine, or briefly - glutamine, is a nonessential amino acid is, as it is synthesized from various organs in the body - the voluntary muscles, the liver, and others.

It is an amino acid that occurs in the greatest amount in the blood plasma - 30-35% and contains about 20% hydrogen in its structure, which makes it the basic carrier of hydrogen for the muscle cells.

How Glutamine Is Produced

Glutamine is normally produced biotechnologically by fermentation of suitable nutrient fluid of bacteria.

What Is the Main Physiological Effect of Glutamine

It increases the secretion of the growth hormone and plays an important role in protein metabolism, for which it is renowned as a good supplement by bodybuilders.

When taken regularly, it protects the muscles from traumatic rupture. The regular adoption ensures that the muscle tissue has a sufficient amount of development. 

Otherwise, a deficit could happen because the other tissues that need glutamine "reach” to the glutamine in the muscles.

Why and How to Take Glutamine

Studies have shown that after a hard workout the levels of glutamine in the body drop to 50%. Therefore it is best to be taken after training. Then it helps restore the muscle glycogen (as readily converted into glucose, without increasing the level of the blood glucose and insulin).

It increases the synthesis of proteins and increases the levels of certain important hormones, inducing muscle growth. The best option for fitness athletes is to take it about 30 minutes after the workout.

What Are Glutamine Optimal Doses

It is believed that the optimum dose of glutamine is 0.2 grams per kilogram of body weight (e.g., a human with a weight of 80 kg would need 16 g). 

The study is that doses of up to 0.3 grams per kilogram of bodyweight are harmless. For short intake, 0.5 grams per kilogram of bodyweight have been given without reported side effects. 

The dose of 2 grams, taken half an hour after exercise produces a significant increase in the growth hormone and a slightly less increase of insulin and testosterone (this has been observed 2 hours after administration).

A dose of 4 grams causes an even greater increase. According to some studies, the growth hormone can be increased to 4 times at this dose.

Possible Side Effects

Glutamine has no side effects, but if you use too excessive doses, you might develop gastrointestinal disorder. If this happens, wait until everything passes and then take smaller doses.

Which Products Are the Main Sources of Glutamine

Glutamine is present in a lot of preparations in a tablet, powder or liquid form. It also participates in preparations that contain a combination of amino acids, in all protein concentrates, and can also be found as a separate product.

Glutamine is present in some complex agents, but in a lower amount. Besides glutamine, they contain other amino acids, L-carnitine, and creatine. Preparations containing glutamine are for oral use and are available in powder, liquid or tablet form.

What Are the Additional Physiological Effects of Glutamine

In the brain, it is a source for the construction of glutamate and it "scums off" the excess ammonia. Glutamine is a component of glutathione - the most powerful antioxidant in the body.

How Is Glutamine Absorbed By the Body

After its intake through the digestive system, glutamine is quickly metabolized to citrulline, arginine, glutamate, and proline.

Which Are the Foods That Contain Glutamine in the Greatest Amount

It is found in foods rich in proteins - such as legumes, meat, fish and dairy products.
