<<Disclaimer: Verify this information before applying it to your situation.>> Hi. Can someone please explain the significance of glutamine. I am a very highly sensitive celiac and just found an ingredient in a shake I drink that is called glutamine. I assume it is a gluten form but when I looked it up I just ended up in circles. My condition is self diagnosed so all of my info comes from here. Also can anyone suggest a product for regularity? Everything I eat seems to get stuck in my gut. It is *very* frustrating. Any suggestions would be tremendously appreciated!
