Bioidentical Hormones: What the Evidence Says
"Bioidentical" is a term that gets used in different ways. Understand what it means, how it differs from compounded products, and what the evidence supports.
"Bioidentical" describes hormones that are chemically identical to those your body produces naturally — most commonly estradiol and progesterone. The term refers to the molecular structure, not to where the hormone comes from or how it is made.
Importantly, many bioidentical hormones are FDA-approved, commercially manufactured, and rigorously tested for dose consistency. These are distinct from "compounded bioidentical hormones," which are custom-mixed by compounding pharmacies and are not FDA-approved or standardized.
Approved vs. compounded
FDA-approved bioidentical products come with known dosing, quality standards, and labeling. Compounded products vary in dose and absorption and are generally recommended only when a person cannot use an approved product for a specific reason.
The term "bioidentical" is sometimes used in marketing to imply that compounded products are safer or more "natural" than approved hormones. The evidence does not support that claim, and major medical societies recommend FDA-approved products first.
What hormone therapy can do
For the right person — typically those within ten years of menopause or under age 60 without contraindications — hormone therapy is the most effective treatment for vasomotor symptoms and can also help with bone density. It is not right for everyone, and personal history matters.
- Relieve hot flashes and night sweats
- Improve sleep disrupted by vasomotor symptoms
- Help preserve bone density
- Support genitourinary symptoms in some cases
A personal decision
Whether hormone therapy is appropriate depends on your symptoms, age, personal and family history, and risk factors. There is no one-size answer. The goal of a visit is to weigh benefits and risks honestly, in the context of your life — not to push a single option.
