This product caused leg cramps .. never get cramps .. 3 days after taking 2pills a day.. developed mild acid reflux and burning .. minor so continued .. by day 7 started getting diarrhea & leg cramps .. stopped pills for 4 days.. symptoms stopped ..when I started back on the pills again after three days the diarrhea returned the acid reflux and some leg cramps which I never get so I went off the medication and all of those symptoms disappeared. I felt I tested it a couple times and it was enough evidence for me because I never have those particular symptoms and for me it was a direct correlation with the medication it just did not agree with my body. I have not had any of those symptoms since I stopped the medication no leg cramps no diarrhea no acid reflux
