Glutamine - FAQ

What is Glutamine?

Glutamine is the most abundant amino acid (building block of protein) in the bloodstream. It is considered a "conditionally essential amino acid" because it can be manufactured in the body, but under extreme physical stress the demand for glutamine exceeds the body's ability to synthesize it. Most glutamine in the body is stored in muscles followed by the lungs, where much of the glutamine is manufactured. Glutamine is important for removing excess ammonia (a common waste product in the body). In the process of picking up ammonia, glutamine donates it when needed to make other amino acids, as well as sugar, and the antioxidant glutathione.

Several types of important immune cells rely on glutamine for energy -- without it, the immune system would be impaired. Glutamine also appears to be necessary for normal brain function and digestion.

Adequate amounts of glutamine are generally obtained through diet alone because the body is also able to make glutamine on its own. Certain medical conditions, including injuries, surgery, infections, and prolonged stress, can deplete glutamine levels, however. In these cases, glutamine supplementation may be helpful.

Who needs it and what are some symptoms of deficiency?

Athletes (Bodybuilders, powerlifters, long distance runner, football players, basketball players, strongman competitors, ect...) who train excessively may deplete their glutamine stores. This is because they are overusing their skeletal muscles, where much of the glutamine in the body is stored. Athletes who overstress their muscles (without adequate time for recovery between workouts) may be at increased risk for infection and often recover slowly from injuries. This is also true for people who participate in prolonged exercise, such as ultra-marathon runners. For this select group of athletes, glutamine supplementation will be very useful.

Glutamine can also aid in healing stomach ulcers and prevent inflammation of the stomach that is caused by chronic use of nonsteroidal anti-inflammatory medications (NSAIDS).

How much should be taken? Are there side effects?

Dietary sources of glutamine include plant and animal proteins such as beef, pork and poultry, milk, yogurt, ricotta cheese, cottage cheese, raw spinach, raw parsley, and cabbage.

Bodybuilders can benefit by taking 10-15 grams of L-glutamine per day, although clinical studies have not determined a precise amount for muscle metabolism optimization.

Glutamine should be taken with cold or room temperature foods or liquids. It should not be added to hot beverages because heat destroys glutamine.

There are no side effects associated with supplementing L-glutamine, because it is a nutrient naturally occurring in the body. Some reports of an upset stomachs are associated with ingesting a high amounts of glutamine, using a smaller doses is recommended if this occurs.
