What Is BHRT? Bioidentical Hormone Therapy Explained

Medically reviewed by Meg LaFerriere, APRN · Regulate Rx, Lee’s Summit, MO

You’ve probably seen “BHRT” on clinic websites and social media, often with big promises attached. Here’s what the term actually means, what it doesn’t, and how to think about your options.

What does “bioidentical” mean?

“Bioidentical” means a hormone has the same chemical structure as a hormone your ovaries made before menopause. Your body can’t tell the difference between the two.

The most common bioidentical hormones used for menopause are:

• Estradiol, the main estrogen your ovaries produce during your reproductive years
• Micronized progesterone, which matches the progesterone your body makes after ovulation
• Testosterone, sometimes used in small doses for specific concerns like low sexual desire

These hormones are usually made in a lab from plant sources such as yams or soy. “Plant-derived” doesn’t mean natural in the body, though. Your body can’t turn a yam into estradiol. The lab does that step.

Are bioidentical hormones FDA-approved?

Many are. This surprises a lot of people, because “BHRT” is often marketed as something separate from regular medicine.

FDA-approved bioidentical options include estradiol patches, gels, sprays, pills and vaginal products, plus oral micronized progesterone capsules. These products are tested for purity and consistent dosing, and they come with standard labeling.

Compounded bioidentical hormones are mixed by a pharmacy for an individual prescription. Compounding can be useful when someone needs a dose or form that isn’t available, or has an allergy to an ingredient in a commercial product.

Tested for dose consistency by FDA standards	Yes	No (pharmacy standards vary)
Can be customized	Limited to available strengths	Yes
Often covered by insurance	Often	Rarely

What does The Menopause Society say about compounded hormones?

The Menopause Society (formerly NAMS) recommends FDA-approved hormone therapy as the first choice for most women. Its 2022 position statement notes that compounded products lack the same testing for safety, purity and dose consistency.

It also notes that compounded hormones may make sense in certain situations, such as an allergy or a dose that isn’t commercially available. That’s a balanced view: compounding has a place, but it shouldn’t be sold as automatically better.

The Menopause Society also cautions against using saliva tests to adjust hormone doses, since saliva levels don’t reliably reflect what’s happening in your body.

What can BHRT help with?

Hormone therapy is the most effective treatment available for hot flashes and night sweats. It’s also FDA-approved to help prevent bone loss after menopause, and vaginal estrogen treats dryness and painful sex.

Many women also notice better sleep once night sweats calm down. Mood and energy may improve when sleep improves, though hormone therapy isn’t a treatment for depression on its own.

What BHRT can’t do is reverse aging or prevent cancer, dementia or heart disease. Any clinic that promises those results is overselling.

Who is a good candidate for BHRT?

You may be a candidate if you have bothersome menopause symptoms and you’re under 60 or within about 10 years of your last period. That’s the group where The Menopause Society says benefits generally outweigh risks for healthy women.

Hormone therapy may not be right for you if you’ve had breast cancer, a blood clot, a stroke, heart disease, liver disease or unexplained vaginal bleeding. Your practitioner reviews your history and labs before recommending anything.

At Regulate Rx in Lee’s Summit, our women’s hormone program starts with a full conversation about your symptoms and goals. If you’ve had a hysterectomy, still have your uterus, or have other health conditions, that shapes which hormones and forms make sense.

Frequently asked questions

Is BHRT the same as HRT?

BHRT is a type of hormone therapy. HRT is the broader term, and it includes both bioidentical hormones and non-bioidentical ones like conjugated estrogens and synthetic progestins. Many FDA-approved HRT products are bioidentical.

Are bioidentical hormones natural?

They’re made in a lab, often from plant compounds, and then processed to match human hormones exactly. “Natural” is a marketing word here. What matters is that the molecule matches yours and the dose is reliable.

Do I need a prescription for bioidentical hormones?

Yes. Estradiol, progesterone and testosterone all require a prescription in the United States. Over-the-counter “progesterone creams” and supplements aren’t regulated the same way and may not contain a meaningful or consistent dose.
