Glutamine is a Nonessential Amino acid and a fundamental organic molecule for the body’s function. It is responsible for Protein synthesis, it helps build muscles, tendons, cartilage, nails and Hormones. Glutamine is more abundant in muscle tissue but it acts as an energy nutrient for immune cells. There are two different forms of this amino acid: L-glutamine and D-glutamine, with L-glutamine being the most common form found in foods and supplements, while D-glutamine does not seem to matter much to the body.
The immune system is made up of cells, tissues and organs that act in the organism’s defense against the harmful effects of external microorganisms. The supplements indicated for immunity act as strengthening agents of this system, increasing the antibodies production and, consequently, its defense activity.
High doses of glutamine have been evaluated and had no side effects, which may indicate that glutamine supplementation is safe, but further studies are needed to prove the safety and toxicity of this supplement. Individuals with liver disease should avoid using glutamine, as it may aggravate this condition. Prescription is recommended in these cases.
Lactulose medications are used to reduce ammonia in the body. Consuming glutamine along with this medication may decrease its effectiveness as glutamine is metabolized into ammonia in the organism.
