Lactose is not added to the formula but it is already present in Thyroid USP raw material as a diluent per USP (United States Pharmacopeia). Lactose is not contraindicated for individuals with allergies to dairy, as lactose is a milk sugar (vs. dairy allergies, which are caused by proteins in milk). It is, however, contraindicated for individuals with lactose intolerance. We have had many physicians reporting no side effects while using Nature-Throid with lactose intolerant patients. The amount is very small – less than 5 mg. per 1 Grain vs. 12,000 – 15,000 mg. in a typical 8 fl. oz. glass of milk.)
