Desiccated Thyroid Over The Counter
Your complete guide to over-the-counter natural desiccated thyroid (NDT) supplements
What is natural desiccated thyroid?
Natural desiccated thyroid (NDT), also called thyroid extract, is a dried powdered thyroid gland from an animal — usually from a pig (porcine thyroid), but it can also come from a cow (bovine thyroid). NDT contains all the thyroid hormones naturally produced by the thyroid gland: T4, T3, T2, T1, and calcitonin.
This guide is for people who want to try an over-the-counter thyroid supplement without needing a prescription. It covers everything you need to know to purchase the right product and use it safely and effectively.

- ✓What natural desiccated thyroid (NDT) is and how it differs from synthetic thyroid hormone.
