I haven't tried this because it contains ascorbic acid, which I have allergic actions to. It they used real vitamin C as a filler ingredient, I would buy the product, even if the doubled or tripled in cost. I don't feel manufacturers should be allowed to call ascorbic acid as vitamin C, because they are chemically different and ascorbic acid is a synthetic ingredient which is not naturally occurring. Unfortunately, all suppliers of DAO seem to used ascorbic acid as a filler ingredient.
