severe stomach reaction
I had a severe stomach reaction to this vitamin. After the second attack of severe, painful stomach gas and vomitting, I suspected my problem was related to this vitamin which I had just started taking. So, I didn't take any for 10 days. Then I took another to "test my theory" that it was this vitamin. As I sat by the toilet most of the night in agony, I kept asking myself why I needed to test my theory. I have never had stomach problems or problems taking multi-vitamins, but something in this is new to me, potent or contaminated. I'm surprised I"ve only seen a few reviews (on other versions of this vitamin on AMazon) that had similar problems. I'd say beware.
