Synthetic B-vitamins seemed to make my symptoms worst. I noticed mild bloating after taking them as well. Pantethine seemed to upset my gut. Right now im experimenting with NAC for acetylhyde levels. God only knows how long that will last until the candida figures a way to utilize it. Seems like the only thing that works for the by products of candida are some of the clays, but i dont like the idea of depending on something that can be constipating/dehydrating.
