Query: No help; caused discomfort

I bought them because they were much more economical than the ones I purchased at the health food store, however, I didn't find this item helped with my digestive issues. Furthermore, I started having severe cramping after taking them. I stopped for a while and started back to make sure that the emzymes were the cause, and sure enough, they started back after I resumed them.
