Bioidentical vs. Standard HRT
Standard HRT
These are FDA-approved hormone medications that may contain:
- Synthetic hormones (like medroxyprogesterone acetate) or
- Animal-derived hormones (like Premarin, derived from horse urine)
- Chemically similar but not identical to human hormones
Bioidentical Hormones
These have a molecular structure identical to hormones your body naturally produces (estradiol, progesterone, testosterone)
Two Types of Bioidentical Products
FDA-Approved Bioidenticals (recommended by most doctors):
- Estrace (estradiol pill)
- Vivelle-Dot (estradiol patch)
- Prometrium (natural progesterone)
- Divigel (estradiol gel)
Compounded Bioidenticals (custom-mixed pharmacies):
- Less regulated, inconsistent dosing
- Often marketed aggressively but lack clinical trial data
Key Honest Points
- "Bioidentical" doesn't automatically mean safer - this is a common marketing claim
- FDA-approved bioidenticals have good safety research
- Compounded versions carry more uncertainty
- The Menopause Society recommends FDA-approved options when possible
