Prevent over-training

Proper nutrition is as much a part of the total fitness package as exercise and living a clean lifestyle. As such, many people incorporate nutritional supplements into their diet. While some are far more common than others (I'm yet to meet someone who actually takes Kratom powder), there seem to be a few supplements that most everyone can agree on. One that immediately comes to mind is Glutamine.

This amino acid becomes depleted when you engage in a rigorous exercise program, which is why it is used most frequently by seasoned trainers. When you exercise hard, you put your body through quite a bit. In fact, go just the slightest bit too far on a regular basis and your body will respond by weakening your immune system and releasing more cortisol. One way to prevent this from happening, as you might have expected, is to replenish your body's glutamine stores.

Though several published studies confirm glutmamine's immune-boosting and muscle-repairing properties, debate rages on over whether or not the research is sound. So, as I generally suggest for all supplements, be sure to first check with your doctor before running out and purchasing glutamine pills or powder.
