Nature-Throid™ vs. Synthetic Thyroid

Nature-Throid™ contains both thyroxine (T4) and triiodothyronine (T3) hormones, which simulate your body’s natural processes. This natural form is more recognizable by the body and may result in a more effective body response. In contrast, synthetic hypothyroidism medications consist of either T4 or T3 hormones, but not both.

The concept behind the use of T4 hormone replacement alone is that synthetic T4 will be converted into T3. A major flaw with this concept is that the conversion from T4 to T3 may not happen, or may only happen at a diminished rate. Therefore, a hypothyroid person would not receive benefits from T4 hormone replacement alone as they may still be deficient in T3.

In reality, many patients do not start to feel relief from their symptoms until they switch from synthetic to Nature-Throid™. Nature-Throid™/Westhroid™ have been used for nearly 80 years, and are two of the safest drugs available.

All prescription thyroid medications, natural or synthetic, must adhere to stringent pharmaceutical standards and processes established by the United States Pharmacopeia (USP) and the FDA. Nature-Throid™ has never been recalled for inconsistent hormone levels, unlike many of the synthetic thyroid medications on the market today.
