Glutamine is a powerful amino acid that your body demands during intense exercise and times of metabolic stress (which includes injury, illness, dieting, etc). Depletion of Glutamine stores can significantly decrease strength, stamina, and recovery. So, as a hard training athlete, it’s very important to supplement your diet with glutamine to maximize your performance in the gym.
However… glutamine can also be one of the most poorly absorbed supplements for a couple of reasons. For one, glutamine, like creatine, is chemically unstable once it’s introduced into fluids and stomach acid. That simply means it degrades over time and loses potency… BEFORE it reaches your cells.
Second, you have lots of “glutamine hungry” receptors in the lining of your stomach. So vast amounts get trapped there and do NOT get into your bloodstream in sufficient quantities to “feed” your muscles with its intense anabolic/anticatabolic properties! No wonder athletes have been slamming down as much as 20 to 30 grams of glutamine per day to get around these problems and hopefully experience at least some of the incredible benefits this amazing amino has to offer!
