I did some reading due to my extreme reaction to biotin. It does cause a candida infection to flair – but not the hyphal phase. Grows on the top instead of putting down the roots. Then…the antifungals come clear it off the top. If one isn’t deficient in biotin in the first place, things don’t get as out of control. I can handle biotin now in very small doses – and I’m going slow with it. Too much and it’s really, really bad. Anyone please correct me if I’m wrong or way off base. But, biotin isn’t an anti fungal per se………it just keeps the yeast from going fungal.
