Natural Desiccated Thyroid (NDT) medications—like Armour Thyroid and NP Thyroid—are derived from pig thyroid glands and are preferred by many hypothyroid patients who haven’t found relief with synthetic options like levothyroxine. 

But as of August 6, 2025, the FDA shocked patients, providers and manufacturers, moving a crucial deadline up from 2029 to August 2026, requiring NDT manufacturers to submit costly Biologics License Applications (BLAs) or potentially face a forced market withdrawal. This shift also restricts compounded NDT and likely bars imports—adding new layers of access and affordability concerns for many, especially those on Medicare or paying cash. 

Though the FDA’s head Dr. Marty Makary has since pledged on X to “ensure access for all Americans,” the window is narrow, and no manufacturer has yet filed a BLA. 

Join us as we unpack what this means, who’s behind these regulatory moves, what patients and advocates are doing about it—and how those of you who rely on NDT can prepare now to protect your treatment options.
