Cheapest Natural Desiccated Thyroid (NDT) from Compounding Pharmacies
Read the Natural Desiccated Thyroid (NDT) background guide →We Do Not Currently Route Natural Desiccated Thyroid (NDT) Quote Requests
Compounded Natural Desiccated Thyroid (NDT / porcine thyroid / Thyroid USP) is subject to FDA enforcement action against unapproved animal-derived thyroid products. US compounding pharmacies are no longer filling NDT prescriptions. FDA-approved NDT alternatives (Armour, NP Thyroid, WP Thyroid) remain available through retail pharmacies with a prescription. If FDA guidance changes, we will revisit.
What patients use instead of compounded NDT
Desiccated thyroid is still available — just not as a compounded preparation. The FDA-approved products below contain the same porcine-derived T4/T3 combination as compounded NDT and are filled at regular retail pharmacies with a prescription from your doctor.
- Armour ThyroidFDA-approved
The original FDA-approved porcine desiccated thyroid, manufactured by AbbVie. Contains a ~4:1 T4:T3 ratio. Widely stocked at retail pharmacies.
Typically $15–$40/month with insurance; cash prices vary by pharmacy — use GoodRx to compare.

FDA-approved porcine desiccated thyroid manufactured by Acella. Same active ingredient as Armour; often a lower-cost alternative.
Often the lowest-cost FDA-approved NDT option. Also stocked at Mark Cuban's Cost Plus Drugs at transparent pricing.
Compare NP Thyroid prices on GoodRx → - WP Thyroid / Nature-ThroidLimited availability
RLC Labs porcine desiccated thyroid with fewer fillers than Armour or NP. Supply has been intermittent over the last several years — check with your pharmacy before relying on it.
Check WP Thyroid availability on GoodRx → - Custom synthetic T3/T4 compoundingStill routable
If you needed compounded NDT because of an allergen or filler issue with commercial products, custom synthetic T3/T4 compounding is not affected by the FDA's NDT action. A prescriber can specify the exact T3:T4 ratio, release profile, and excipient profile you need.
