Bioidentical Hormones vs. Standard HRT
Standard HRT
These are conventional hormone replacement therapies using synthetic or animal-derived hormones that may not be chemically identical to what your body produces. Examples include:
- Premarin (estrogen derived from horse urine)
- Provera (synthetic progestin/medroxyprogesterone)
- Prempro (combination product)
Bioidentical Hormones
These have a molecular structure identical to your body's natural hormones. They include:
FDA-approved options:
- Estrace (estradiol pills)
- Vivelle-Dot (estradiol patch)
- Prometrium (progesterone - body-identical)
- Bijuva (combo capsule)
Compounded options (custom-made at pharmacies like Medically Necessary Compounding or local compounding pharmacies)
Key Differences
| Factor | Standard HRT | Bioidentical |
|---|---|---|
| Molecular match | Close but different | Identical to body's hormones |
| FDA regulation | Yes | Varies |
| Customization | Limited | High (compounded) |
Important Note
Consult your doctor or a menopause specialist - the evidence base for FDA-approved bioidenticals is stronger than for compounded versions, which lack standardized testing.
