Bioidentical Hormones vs. Standard HRT
Standard HRT
These are hormone medications that may be synthetic or derived from animal sources, with molecular structures that may differ slightly from human hormones.
Examples:
- Premarin (conjugated equine estrogens, from horse urine)
- Provera (medroxyprogesterone acetate - synthetic progestin)
- Prempro (combined estrogen/progestin)
Bioidentical Hormones
These have a molecular structure identical to hormones your body produces naturally.
Examples:
- Estrace (estradiol) - FDA-approved bioidentical estrogen
- Prometrium (micronized progesterone) - FDA-approved bioidentical progesterone
- Vivelle-Dot or Climara patches - bioidentical estradiol
Key Distinction: FDA-Approved vs. Compounded
- FDA-approved bioidenticals (above) have been tested for safety and consistency
- Compounded bioidenticals (custom-mixed by pharmacies) are not FDA-regulated and vary in quality
My Recommendation
Talk to your doctor about FDA-approved bioidentical options like Prometrium and Vivelle-Dot — you get the "natural" molecular match with regulatory oversight.
Always consult your healthcare provider for personalized guidance.
