Bioidentical Hormones vs. Standard HRT
Standard HRT
These are FDA-approved hormone medications that may contain:
- Synthetic hormones (like medroxyprogesterone acetate)
- Animal-derived hormones (like Premarin, made from pregnant mare urine)
- Chemically modified versions that work in your body similarly to natural hormones
Bioidentical Hormones
These have a molecular structure identical to hormones your body produces naturally. Many FDA-approved options exist, including:
- Estradiol patches (Vivelle-Dot, Climara)
- Estradiol gels (Divigel, Estrogel)
- Progesterone capsules (Prometrium - made from yams)
The "Compounded" Distinction
Some bioidentical hormones are custom-compounded by specialty pharmacies (like Women's International Pharmacy or Belmar Pharmacy), mixed to individual specifications - but these are not FDA-approved and have less quality oversight.
Key Takeaway
- FDA-approved bioidentical options offer a good middle ground - natural molecular structure with regulatory oversight
- The marketing term "bioidentical" is sometimes overstated - what matters most is the type, dose, and delivery method
Consult a menopause specialist (look for NAMS-certified practitioners) for personalized guidance.
