Looking at Glutagenics it includes 3,500 mgs of L-Glutamine which is a high dose since dv is closer to 500mgs from my understanding. You could buy a LOT of L-glutamine powder rather than coughing up money to from Metagenics. Aloe vera is rather cheap as well. Mostly I am not a fan of Metagenics since every dollar you pay for their products, roughly 50% goes to the practitioner who convinced you to use that product. I know, I've glanced at the mark up sheet at my Gp's office.
