I am not sure about what ph favor candida to survive better. I found some scientific reports which stay candida albicans can grow better as a yeast in acid ph, but it can change to fungal form better in an alkaline ph. Otherwise, I know sodium bicarbonate is used to treat vaginal candidiasis in women. I may be wrong but I understand bacterias can not survive in very acid ph and fungus can not in very alkaline ph. This is a problem because we find contradictory information about it.
