No... However Miracle-Mineral-Supplement is an oxidant... Vitamin C is an antioxidant... I personally choose to not take vitamin c while I am taking Miracle-Mineral-Supplement . The Miracle-Mineral-Supplement is not really that "tasty" and I don't want to take anything that will neutralize it... that is why I choose to lay off the MMS one week a month and load up on vitamin c when I am not on MMS. I am not really sure about the Iodine but that is the only other thing I think it might affect. As far as the other minerals go...I just take them as I would otherwise.. far as I know the MMS has no effect. I am on a veggie diet..modified..in that I still eat milk products, eggs, and fish.
