The REAL facts about Westhroid.

Same formula, different name.

Nature-Throid and Westhroid are identical formulations. Having one medication under two names caused some confusion; therefore, we made the decision to market under one name: Nature-Throid.

Westhroid was one of the first hypothyroid medications and has never been recalled for inconsistent T4 or T3 hormones. Today the hypoallergenic, low-cost formula is still available at your local pharmacy in 5 strengths. Nature-Throid may be carried at more pharmacies and is available in 13 strengths.

  • T4 & T3 replacement hormones (desiccated porcine thyroid)
  • Thyroid cofactors (T1, T2, calcitonin and iodine) naturally occur in trace amounts
  • Gluten free
  • Available in 5 strengths

Due to the limited strengths of Westhroid, you may be interested in learning more about Nature-Throid. We also manufacture WP Thyroid, the purest thyroid medication formulated with only two all-natural inactive ingredients.
