The amino acid L-Glutamine is essential to removing common waste products in the body, especially ammonia. Ammonia is a gas that can be quite irritating. By alternating the compositions of microbes in the gut, improving insulin sensitivity and reducing inflammation, L-Glutamine can boost the weight loss process. It is needed for normal digestion as well as brain functioning and could keep the immune system working properly. The body may benefit most from taking L-Glutamine during its fasting state so it’s recommended that it should be taken at night.
