Few terms in the menopause world cause as much confusion, and as much clever marketing, as "bioidentical hormones." You will hear them described as natural, safer, and customized just for you, often sold through glossy clinics and custom-compounded prescriptions. Some of that is fair, and some of it is a sales pitch wrapped around a real medical fact. Here is the honest version, from a publication that sells none of it.

To be clear: Menova is independent, we sell no hormones, and we are not your doctor. We have no compounded-hormone clinic to refer you to and no product to move, which is exactly why we can untangle this plainly.

What are bioidentical hormones?

The word simply means a hormone that is chemically identical to the ones your own body makes, such as estradiol and progesterone. That is a legitimate scientific category, not a brand. The crucial point most marketing skips is this: many bioidentical hormones are already FDA-approved and widely prescribed. Estradiol patches, gels, and sprays, and micronized progesterone capsules, are bioidentical and have gone through rigorous testing for safety, dosing, and purity. So if a clinician offers you a bioidentical option, that can absolutely mean a well-studied, FDA-approved product.

Are compounded bioidentical hormones safe?

The marketing usually is not selling those approved products. It is selling compounded bioidentical hormone therapy, often shortened to cBHT: custom mixtures prepared by compounding pharmacies, frequently dosed using saliva or blood tests and promoted as uniquely tailored to you. This is where independent experts urge caution:

  • Compounded products are generally not FDA-approved, which means their exact dose, absorption, and purity are not verified the way approved products are. A 2020 report from the National Academies of Sciences, Engineering, and Medicine concluded there is insufficient evidence that compounded hormones are safer or more effective, and discouraged their routine use.
  • The "customized" testing is shaky. Saliva hormone testing, often used to justify custom blends, is not considered a reliable basis for dosing, because hormone levels fluctuate constantly in this stage of life.
  • "Natural" does not mean safer. Compounded hormones carry the same underlying risks as any hormone therapy, but with less oversight, and some have lacked the progestogen protection the uterus needs.

Can hormones really be "balanced"?

A lot of cBHT marketing is built on the idea of restoring perfect hormonal balance, measured by a test and corrected by a custom cream. That framing oversells what anyone can deliver. Menopause is not a deficiency to be perfectly dialed in; it is a transition, and treatment aims at relieving symptoms safely, not at chasing a number on a saliva test.

Are bioidentical hormones a good choice?

So are bioidenticals a good choice?

They can be, when they are the FDA-approved kind. For many women, an FDA-approved estradiol patch with micronized progesterone is a mainstream, evidence-based, bioidentical option, and a reasonable thing to ask your clinician about. The skepticism is aimed at unregulated compounded blends sold on promises of being natural and customized. If you are paying out of pocket at a clinic that downplays risks and leans on saliva testing, that is a moment to slow down and ask questions.

Questions to ask about bioidentical hormones

A few questions cut through the marketing quickly:

  • Is what you are recommending an FDA-approved product, or a compounded one?
  • If compounded, why, when an approved version exists for my situation?
  • How are you protecting my uterine lining if I am taking estrogen?
  • What are the actual risks for someone with my history?

If you want to walk into that conversation organized, the free Menova self-check helps you lay out your symptoms first. Our companion article on compounded versus FDA-approved hormones goes deeper on the safety distinction, and our piece on whether HRT is safe covers the broader risk-benefit picture.
