Bioidentical Hormones vs. Standard HRT
Standard HRT
These are hormone medications that may be synthetic or animal-derived, with molecular structures that may differ slightly from your body's natural hormones.
Common brands:
- Premarin – estrogen derived from pregnant mare urine
- Provera – synthetic progestin (medroxyprogesterone)
- Prempro – combines both above
Bioidentical Hormones
These have a molecular structure identical to hormones your body naturally produces. They can be:
- FDA-approved products like Estrace, Vivelle-Dot, Prometrium, or Bijuva
- Compounded formulas custom-mixed by pharmacies (like those through Winona, Midi Health, or Alloy)
Key Differences
| Factor | Standard HRT | Bioidentical |
|---|---|---|
| Molecular match | May differ | Identical to body's hormones |
| Regulation | FDA-approved | FDA-approved OR compounded |
| Research base | Extensive | Growing |
Important Notes
- FDA-approved bioidenticals (like Prometrium) have solid safety data
- Compounded bioidenticals have less regulatory oversight
- Many doctors consider FDA-approved bioidenticals the best of both worlds
Always consult an endocrinologist or menopause specialist before choosing. Services like Midi Health connect you with hormone specialists who can guide this decision.
