A: Lactose is not added to our 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.

A: Since WP Thyroid is uncoated and formulated with minimal pure ingredients, the tablets can change color by absorbing ambient humidity. If the tablets are stored in their original container and at room temperature (59° (15°) – 86° F (30° C) with an ambient humidity of 10-65%, no discoloration occurs. However, exposed tablets outside of proper storage conditions still conform to USP specifications for both T4 and T3 potency and stability.

Warnings: Don’t Take For
Use WP Thyroid® and Nature-Throid® exactly as prescribed. Unless otherwise directed by your doctor, do not stop taking either medication or alter how often it’s taken. Many factors can contribute to the length of time symptoms are alleviated, though generally people feel an improvement within a few weeks. For some, though, improvement in symptoms may take up to three months. Your doctor will determine which dose is right for you. If any life changes or new symptoms occur, consult your doctor to adjust your dose. Continue to see your doctor until your dosage levels prove stable based on your lab work, then continue to see your doctor at their request. Thyroid replacement therapy is usually taken for life.
