L-glutamine, what it is used for is a question many people ask. In this article we are going to address the doubts about this topic. From the effects it has on the human body and its benefits and properties to the way to take it to achieve the best results with 500 mg and 1000 mg.
What glutamine is used for
It is a non-essential amino acid that is part of human proteins. It is the amino acid present in the greatest amount in the body so it is very important for several functions.
We need it for nourishment, to increase muscle mass, improve energy and endurance during exercise and to be stronger when stress occurs.
You can take it in capsules, powders and supplements from various l-glutamine brands which, if they are good quality, can have very important effects on health. Its benefits when taken properly are impressive so we are going to see what glutamine is used for:
- Increase muscle size and create new fibrous tissue.
- Endure exercise for a longer time.
- Have greater endurance in stressful situations.
- Improve the absorption and assimilation of nutrients from food, supplements and everything you ingest in your bodybuilding, sports or normal diet.
- Improve the production of antibodies and raise the body’s defenses.
- Reduce joint inflammation.

Can it be taken with other amino acids?
Yes. There is no contraindication and it is even beneficial to take glutamine with amino acids. It improves nutrient absorption and has a property that stimulates growth hormone when included in the diet together with vitamin B1 which is thiamine. This increases and improves the transformation of energy from carbohydrates and allows their metabolization together with fats and other nutrients. In addition, you can take L-glutamine with:
- Arginine without contraindications for health since it improves metabolism, the circulatory system and reduces the side effects of diabetes.
- Creatine to increase muscle mass and performance. Although creatine is not an amino acid it is usually purchased together.
- Carnitine against chronic fatigue and fibromyalgia symptoms. L-carnitine is another non-amino acid supplement but it is often used in the same way and together with glutamine.
- L-Ornithine and its properties to create nitric oxide as a vasodilator, reduce ammonia in the body, regulate sexual function and enhance the cardiovascular system.
- Lysine because its benefits and uses help control cholesterol. It is also used at the same time with L-carnitine. Its function in metabolism regulates fat and prevents the development of disorders in the liver and heart.
The functions of l-glutamine, the assimilable form in the body, also mean that less energy has to be spent on the transformation of the structure of glutamic acid into the amino acid glutamine form. The body becomes supplied with glutamate amino acids that act in the cerebral cortex. It is a neurotransmitter that interacts with proline, arginine, hydroxyproline and ornithine.
