wow, a whole bottle? haha! well if that dont do it i dont know what will! i would have put a cup or two in there. well if there is a lingering ACV taste afterwards you can nuetralize it with baking soda.
i actually use swanson brand grapeseed extract which is the least expensive on the net and it seems to be just fine.
i haven't really looked into EDTA so i cant tell you about it.
also have you had your vitamin D levels checked? D is what helps you to utilize the calcium you have properly. huge amounts of poeple are D deficient.
