Review on Now Foods L-Glutamine Pure Powder, 16 Ounce (Pack of 2): Boost Recovery and Strengthen Immunity by Angie Strongheart

Excellent product and very good price for this lot. I love it for boosting immune system function after an intense workout, especially if you're not getting as much sleep as you'd like. I noticed a difference in this app. In terms of muscle growth, I haven't noticed any difference, but most experts say that a normal diet is enough to build muscle. It seems that muscle recovery can sometimes take too much of your dietary glutamine away from immune system function. Immune cells use glutamine as their primary energy source, so adding it to this supplement may help minimize the breakdown of the immune system after an intense day of exercise.
