Glutamine

Glutamine is an amino acid which plays an important role in the rebuilding of tissue in the body.

Glutamine exists in two forms: L-glutamine and D-glutamine. The form found in foods and supplements is L-glutamine. Some supplements list it as L-glutamine, but others simply use the broader term glutamine.

It is considered a conditionally essential amino acid, meaning that it must be obtained from the diet (or supplement) under certain conditions, such as injury or illness.

Glutamine for Immune Health

Glutamine plays a role in the function of the immune system which can be compromised when insufficient amounts of glutamine are available.

Studies have also reported that glutamine supplements may improve health and decrease infections.

Glutamine for Gut Health

Glutamine is an important energy source for intestinal and immune cells. 

It also helps maintain the barrier between the inside of your intestines and the rest of your body, thereby protecting against leaky gut syndrome. 

Glutamine for Muscle Gain and Exercise Performance

Some research has reported that glutamine supplements may decrease muscle soreness and improve recovery after intense exercise.
