The FDA has just dropped a bombshell that could affect nearly 2 million Americans taking natural thyroid medication. In a controversial move, they've reclassified desiccated thyroid extract, or DTE, as a biologic rather than a traditional drug. This means compounding pharmacies have exactly one year before they must stop making the customized thyroid medications that countless patients depend on. Critics are calling foul, arguing the decision is based on an inactive pig protein that gets digested in your stomach anyway, and pointing out that the real active ingredients - T4 and T3 hormones - haven't changed. What's really raising eyebrows is that this shift appears linked to a petition from AbbVie, the company behind brand-name Armour Thyroid, potentially setting up a monopoly situation.
