I go to Dr. Frackelton in Westlake, Ohio for cancer prevention. (I already had it once) I have suffered from spastic colon off and on for years. I was really in pain one time when I went for my routine blood work and mentioned it to him. He said, "I know what will fix you up right now. " He told me to take 1 tsp of l-glutamine 3 times a day. I had been suffering with this for 4 weeks. I had already gone to my regular doctor who prescribed a medicine that did give me some relief from the pain. I quit taking that medicine the day before I went to see Dr. Frackelton. I took the l-glutamine later after I got home. I was taking my third teaspoon of it when I realized that I was fine!!! It worked that fast. When Dr. Frackelton told me it would fix me up right now, he was right! The l-glutamine really worked. I hope this helps someone.
A natural doctor recommended the powdered supplement l-glutamine for my IBS. He said to take 5g(1 teaspoon) twice a day with juice or water but don't take it with protein at the same time because it will lesson the effect. It works! I have had far fewer attacks. It is inexpensive and easy to find because weightlifters also use it for muscle building benefits.
