Bioidentical Hormones vs. Standard HRT
Standard HRT
These are FDA-approved hormone medications that may include:
- Synthetic hormones (like medroxyprogesterone acetate) or
- Horse-derived estrogens (like Premarin, from pregnant mare urine)
- Consistent, tested dosing
Bioidentical Hormones
Hormones chemically identical to those your body naturally produces, derived from plant sources (soy/yams).
Two Categories of Bioidentical Options
FDA-Approved Bioidentical Products (generally recommended)
- Estradiol patches – Vivelle-Dot, Climara
- Estradiol gels – EstroGel, Divigel
- Progesterone – Prometrium (oral capsule)
- These have standardized dosing and safety testing
Compounded Bioidentical Hormones (more controversial)
- Custom-mixed by compounding pharmacies
- Often marketed as "natural" and personalized
- Not FDA-approved for safety/efficacy
- Quality can vary significantly between pharmacies
Key Considerations
- FDA-approved bioidentical options offer the best of both worlds - natural molecular structure with proven safety data
- Most major medical organizations do not recommend compounded versions over regulated alternatives
- Always consult an endocrinologist or menopause specialist for personalized guidance
The marketing around "bioidentical" can be misleading - FDA-approved options are your safest starting point.
