Glutamine is the most abundant amino acid in the human body. It is one of the molecules that form the protein needed to nourish and repair tissues such as skin, nails, muscles and organs, in addition to acting as a nutrient for immune cells and presenting an important anabolic function, promoting muscle growth.
Glutamine boosts immunity?
According to a review of 25 studies published in the European Journal of Clinical Nutrition, supplementing the amino acid does not improve the immune system or body composition of athletes, nor does it influence aerobic performance, bringing benefits only to those who practice overtraining (resulting condition from exercising more than their body is able to recover) and suffering from serious conditions such as cancer and major burns.
Safety and Side Effects
Excess glutamine can cause insulin resistance, a condition similar to type 2 diabetes and kidney failure, in addition to prolonged consumption affecting and decreasing the body’s natural production.
Due to the lack of proof of the benefits of glutamine supplementation in healthy people, there is no daily recommendation defined by Anvisa, so it is important to consume it only with the recommendation of a qualified professional.
