I've been taking a drink of water, unsweetened cranberry juice, lemon juice and Braggs Apple Cider Vinegar every day for an unrelated health issue and this morning saw a white mass inside a stool. I don't know if this is candida or not but if so, I'm guessing the Braggs ACV would be the active ingredient.
White is yeast so it is VERY likely that it was candida (or else another fungus) and YES, ACV is a powerful antifungal. It works especially well in enemas (only one spoonful though).
