Bioidentical vs. Standard HRT
Standard HRT
These are FDA-approved hormone medications that may include:
- Synthetic hormones (like medroxyprogesterone acetate) or animal-derived hormones (like Premarin, from horse urine)
- Consistent, regulated dosing
- Extensive clinical trial data on safety and efficacy
Common brands: Premarin, Prempro, Provera
Bioidentical Hormones
These have the same molecular structure as hormones your body produces naturally
Two types:
FDA-approved bioidenticals:
- Brands like Estrace, Vivelle-Dot, Prometrium, Divigel
- Standardized doses, regulated quality
- Good safety data
Compounded bioidenticals:
- Custom-mixed by compounding pharmacies
- Often marketed as more "personalized"
- Less regulated - the FDA has raised concerns about inconsistent dosing and unproven claims
Bottom Line for Shoppers
- FDA-approved bioidenticals (like Prometrium or Vivelle-Dot) offer a good middle ground - natural molecular structure with regulatory oversight
- Be cautious of compounding pharmacies making bold claims without solid evidence
- Major medical organizations generally favor FDA-approved options over custom compounded versions
Always consult your doctor - the best choice depends on your specific health history.
