Supports immunity, gut health & muscle repair after exercise

For Digestive & Leaky Gut Repair

Muscle Building & Muscle Recovery 

L-Glutamine is one of the 20 fundamental amino acids involved in protein synthesis; it is also the most abundant, forming approximately one fifth of the amino acid pool in the human bloodstream. Glutamine is critical for a wide variety of essential functions, including optimal operation of the kidneys, pancreas, gall bladder, liver, the small and large intestines, and the brain. However it is best known for boosting immunity, helping to heal the gut lining and enhancing muscle growth.

L-Glutamine’s importance toward good immunity is known to be two-fold: it directly supports the immune system during times of stress through its ability to help produce glutathione, the body’s most powerful antioxidant. It also indirectly supports immunity by reducing intestinal permeability or “leaky gut”, inhibiting undigested particles from accessing the bloodstream, which can trigger an immune response. L-Glutamine stimulates the production of human growth hormone (hGH), which is essential for building muscle and maintaining youthful cellular function. Since L-glutamine is depleted by intense exercise, it is an important component of sports nutrition.

Those who are under undue stress, suffer from leaky gut or have weakened immunity may benefit from L-glutamine; as well as those seeking to increase their muscle mass and improve exercise recovery.
