Official answer


Westhroid is NOT the same as WP Thyroid, but it is the same as Naturethroid. All three thyroid preparations, Westhroid, WP Thyroid, and NatureThroid are manufactured by RLC Labs. The difference between Westhroid and WP Thyroid is that WP Thyroid is one of the purest thyroid preparations available and it contains only 2 all-natural inactive ingredients:

  • Inulin (from chicory root)
  • Medium Chain Triglycerides (from coconut).

WP thyroid is also available in 8 strengths ranging from ¼ grain (16.25 mg) to 2 grain (130 mg).

Westhroid contains the following 7 inactive ingredients:

  • Colloidal Silicon Dioxide
  • Dicalcium Phosphate
  • Magnesium Stearate
  • Microcrystalline Cellulose
  • Croscarmellose Sodium
  • Stearic Acid
  • Opadry II 85F19316 Clear – tablet coating

Westhroid is available in 5 strengths ranging from 2 grains (32.5 mg) to 3 grains (195 mg).

Neither Westhroid nor WP Thyroid contain any artificial colors or flavors, corn, peanut, rice, gluten, soy, yeast, egg, or fish/shellfish.
