Is supplementing with Glutamine beneficial to exercise performance?

Asked by: Colleen Keo

Glutamine, or L-glutamine, is a naturally occurring non-essential amino acid that is commonly stored in muscles and released into the bloodstream during times of physical stress. Athletes who take glutamine supplements generally do so in order to prevent muscle breakdown and to improve immune system functioning.

Does glutamine help with working out?

Research has shown that athletes can benefit from L-glutamine supplementation to decrease muscle soreness and improve recovery time. This amino acid plays a crucial role in controlling glucose (energy) uptake by the muscles after exercise, which can help restore their energy stores for your next workout.

Should athletes take glutamine?

With a balanced diet of greens and protein, most athletes do not need to take a glutamine supplement. However, if your training load is abnormally high and your diet is unable to meet your needs, then supplementation may be beneficial.

Results of the cumulative data on glutamine supplementation show that glutamine may have athletic performance enhancement ability and because of this may serve as an ergogonic aid.

How much L-glutamine should an athlete take?

[2]The ideal amount of daily glutamine intake to achieve the most effective results for athletes has not yet been established. However, the recommended dose is about 2 to 5 grams twice or three times a day. With a very intense sports activity, it is recommended to take 10 g of glutamine twice a day.

Is glutamine better than creatine?

Although both glutamine and creatine provide numerous health and performance benefits, creatine and glutamine serve very different functions.
