Even though Jim says to avoid Vitamin C too close to the dosage of Miracle-Mineral-Supplement , I think other antioxidants should be avoided as well. Chlorine dioxide is an oxidant. It would not hurt you in any case. It just renders both useless as they balance each other. I consider this for vitamin C, selenium, and foods. I typically take Miracle-Mineral-Supplement before bed or 3 hours after my last meal. That solves the problem for me. I also read, as did Alexandria, that there is no KNOWN interaction with drugs. However, I would follow the same rule as for antioxidants.
