Glutamine is a key amino acid that supports muscle and gastrointestinal tract health while also promoting intestinal mucosa health. Glutamine serves as a critical source of energy for intestinal cells, which help to maintain the barrier between the intestines and the rest of the body. This barrier prevents bacteria or toxins from leaking from the intestines into the rest of the body. Additionally, glutamine is necessary in the production of glutathione, a key liver nutrient which prevents damage to important cellular components such as free radicals, peroxides, and heavy metals.

Glutamine, the most abundant amino acid in the body and one of the few which can cross the blood-brain barrier, plays an important role in biological functions including protein synthesis. Research has shown that glutamine supports the preservation of muscle mass so it may be helpful in post-exercise recovery. During catabolic states or stress, as in post-exercise, it supports muscle recovery and glycogen reloading.
