Natural Desiccated Thyroid (NDT) in Danger

A recent move by the FDA that could affect millions of people taking natural desiccated thyroid (NDT) medications such as Armour Thyroid, NP Thyroid, and others.

On August 6, 2026, the FDA plans to take enforcement action against any manufacturer making NDT.

Why the FDA says they’re doing this:

  1. NDT is not formally FDA-approved
  2. Since 1968, there have been just over 500 reported adverse events
  3. They cite a theoretical risk of impurities or infections from animal-derived thyroid tissue

Here’s what the record actually shows:

  • NDT has been in use since 1891 and was grandfathered in when the FDA began regulating medications in 1938
  • FDA records show 2,851 adverse reactions for NDT since 1968 – compared to 76,557 for synthetic T4-only medications in the same timeframe
  • There has never been a documented case of infection or harm from impurities in NDT

What this could mean:

  • NDT could disappear entirely
  • Armour Thyroid may be the only brand left
  • Or nothing may change—but history suggests we should prepare for the worst

In my years of practice, I’ve seen many people feel far better on NDT than on T4 alone—and large studies confirm this isn’t unusual.

Please help

There is no legitimate reason for the FDA to take away natural thyroid. Millions of people will suffer unnecessarily.

I’m asking for your help even if this does not apply to you because medical freedom is at stake for all of us.
