Good for GI

Posted by Reviewer3319590 on Oct 11, 2016

I like the size of the pill, easy to swallow and doesn't get stuck in my throat. These are great for GI health. Helps with bloating and aids digestion.

I think it's quite convenient way to take this supplement . I'm not a body builder , so I think that this product works nice enough for a person that works three times a day lightly.

Why the sorbitol?

Posted by Reviewer2531700 on Jun 04, 2015

It never occurred to me to check for the ingredients, thinking I was just getting L-Glutamine. After hours of belly pain, I checked and saw it contains sorbitol. Why? Don't you just swallow this down?? To the trash with this.

Seems to Work

Posted by Reviewer2508562 on Nov 06, 2014

I use this to help with muscle recovery and also, to recover from intestinal damage from gluten. Seems to work for both, although I am not sure if diet and lifestyle could be the reason. Regardless, I am sticking to this!
