The amino acid L-Glutamine is the most metabolized amino acid in the body. About 60% of the amino acids in our muscle mass are L-Glutamine. During hard training, the levels in the body decrease drastically and in case of lack, the body is put in a catabolically degrading position.
During hard training, an intake of 10-20 grams of L-glutamine per day is recommended to ensure the body's needs. Athletes have reported that an increased intake of the amino acid L-Glutamine helps them avoid colds. Glutamine supplementation has been shown to improve the function of the intestinal mucosa and thus contribute to the stabilization of the immune system.
Today, there are over 100 studies and scientific publications that support positive effects from the use of the amino acid Glutamine.
