Glutamine As An Exercise & Sports Supplement
In addition to the many benefits of l-glutamine, glutamine can also bring benefits specific to those who exercise.
As a supplement l-glutamine is inexpensive and popular with many body builders, athletes and other people who exercise.
The benefits of l-glutamine supplements for exercise are marketed accordingly.
Glutamine supplements may:
- prevent a fall in glutamine levels after exercise – leads to faster recovery with fewer aches and pains
- maintain muscle mass – whilst dieting, cortisol, a steroid hormone is released.
- break tissue down
- reduce the synthesis of protein
- help convert protein into glucose
By supplementing with glutamine, cortisol can use glutamine from the blood and not take it from the muscles.
Supplements Of Glutamine May Also:
- stimulate muscle growth – a popular reason for trying this supplement by body builders and weight lifters; however no evidence at present to support this 
- increase growth hormone levels
- improve endurance
- regulate protein syntheses – helps maintain muscle mass
Also, as an anti catabolic, glutamine may prevent the breakdown of muscle tissue during intense exercise & workouts. It may achieve this by increasing cell volume through water drawn into the muscle cells.
When cell volume increases, there is a reduction in the effectiveness of enzymes thought to break down muscle proteins. An increase in cell volume may also reduce the effects of stress hormones which are released in greater concentrations after exercise.
