I agree with you that SF- 722 isn't an strong product against candida. It could be effective but work slow. Die- off can happen with any product as long you don't feed candida. How you said, it is very difficult to realize when is hypoglycemia, food intolerance, toxicity from a supplement, or die-off. I think die-off is a must and something we all have to live. More or less severe nobody escape of it.
