BHRT is not automatically “safer” than other hormone therapy. Doctors generally say that FDA-approved bioidentical hormones can be appropriate for some patients, but compounded bioidentical hormones have less evidence, less regulation, and more uncertainty about dosing and long-term safety.[6][7][9]
What doctors commonly say:
- FDA-approved bioidentical hormones are tested for safety, and they carry the same kinds of risks as hormone therapy in general, including blood clots, stroke, gallbladder disease, and possibly higher risks of breast cancer or heart disease with older age or longer use.[6][9]
- Compounded BHRT is the main concern. ACOG says there is a lack of high-quality data on its safety and effectiveness, and it should not be prescribed routinely when FDA-approved options exist.[7]
- There is no good evidence that compounded bioidentical hormones are safer or more effective than standard FDA-approved hormone therapy.[8][9]
- Compounded products may be more variable in potency and quality, which can raise the risk of underdosing or overdosing.[1][4][8]
What the evidence suggests:
- Short-term studies have not shown major changes in some lab markers, but the evidence is limited and mostly short term, often up to about 1 year.[7]
- For outcomes people care about most—like breast cancer, endometrial cancer, and cardiovascular disease—the data on compounded BHRT are inadequate.[7]
- Some reviews have suggested possible benefits for certain bioidentical formulations, but later medical guidance still emphasizes that “bioidentical” does not mean safer, especially when compounded.[10][9]
In practical terms, doctors usually distinguish between:
- FDA-approved bioidentical hormones: generally considered acceptable when hormone therapy is indicated.[6][9]
- Compounded BHRT: used more cautiously because of weaker evidence and quality-control concerns.[7][8]
