I hadn't taken calcium since the calcium carbonate incident in April. I wanted to prevent bone loss, etc. so I started taking calcium citrate supplements 2 weeks ago - 300mg once a day with food. I started having more symptoms and a few days ago it got real bad. I'm mainly noticing spasms in both upper and lower GI, and gas throughout. I don't think I've had so much gas before.So I've stopped taking the calcium as well as 2 other suspects, stevia and natural mustard(no sugar, no chemicals). The symptoms are getting better. This morning I saw my gyne and she said if I eat enough spinach, broccoli and oatmeal I don't need calcium supplements.Has anyone else had such a reaction to calcium citrate?
