Not diarrhea, but just a weird, irritable feeling. I started taking 1,000 mg per day. Yes, I got that strange irritable gut feeling on the first day. The guy whose web-site I mentioned said that people with food allergies can tolerate less vit. C. before getting diarrhoea (what he calls the bowel tolerance level). But I reasoned that the body may be in serious vit. C. depletion due to CD related malabsorption, so I pressed on with the Vit C. doses (1 gram is not an enormous dose anyway) and found that the gut irritation receded on the second day. > Then again yesterday I took only 500 mg of citris bioflavanoids capsule > and last night got cramps and diarrhea. Same question -- sensitivity to > citris maybe, or just "cleaning house?" Anyone else have this > experience with ascorbic acid or other forms of vitamin C? I guess it is just gut sensitivity. The 'cleaning house' may come later, as your vit. C levels increase significantly. Max
