The REAL facts about Westhroid.

Westriud Bottle

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.

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.

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 Westhroidwith 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.)
