"Hormone Balancing" and Bioidentical Hormone Claims Checked
What "hormone balancing" and "bioidentical" mean, what FDA, the National Academies and menopause specialists say about compounded hormones, and questions to ask before starting.
Content last updated . This page has not been medically reviewed.
Urgent first
Call 911 for chest pain, sudden weakness or numbness on one side, trouble speaking, or sudden severe headache, because hormone medicines can raise the chance of blood clots, heart attacks and strokes in some people. [1] Any vaginal bleeding after menopause should be reported to a health care provider, because it may be a sign of an urgent medical problem. [1] Do not stop or change prescribed hormones, thyroid medicine or other medicines without your prescriber.Plain-language terms
Hormones are the body's chemical messengers. [2] Too much or too little of a certain hormone can be serious, and laboratory tests can measure hormone levels in blood, urine or saliva when a provider suspects a hormone disorder. [2]"Hormone balancing" is a popular phrase rather than a medical term in the sources we read. It is not defined as a diagnosis there; hormone disorders are the diagnoses, and a clinician decides whether tests are needed. [2] For thyroid, adrenal, PCOS and menopause topics see thyroid and fatigue, cortisol and adrenal fatigue and perimenopause and menopause.
"Bioidentical" means a hormone with the same chemical structure as one the body makes. FDA states that it has approved drugs containing hormones identical to those women make naturally. [1] So "bioidentical" does not mean "unapproved." The issue is compounded bioidentical products, which a pharmacy makes to order.
Claims checked
| Claim | What the sources found | Label |
|---|---|---|
| Compounded "bioidentical" hormones are safer or more effective than approved ones | FDA does not have evidence that they are safe and effective, or safer or more effective than FDA-approved hormone therapy [1]. The National Academies found marketing claims were not supported by evidence from well-designed, properly controlled studies [3] | Marketing claim |
| Estriol is a "safer" estrogen | FDA says it has no evidence that estriol drugs are safe, effective or "safer forms of estrogen," and that there are no FDA-approved drugs containing estriol [1] | Insufficient evidence |
| Compounded products are tested like approved drugs | FDA does not verify the safety, effectiveness or quality of compounded drugs before they are marketed [4] | Marketing claim |
| "Natural" herbs or creams relieve menopause symptoms | FDA says it does not know if herbs or other "natural" products are helpful or safe [1]. For botanicals see botanicals for menopause | Insufficient evidence |
| Hormones slow aging, wrinkles or raise sex drive | FDA says studies have not shown this [1] | No good evidence of benefit |
| Approved menopausal hormone therapy relieves hot flashes and vaginal symptoms | The North American Menopause Society calls hormone therapy the most effective treatment for vasomotor symptoms and the genitourinary syndrome of menopause [5] | Established, with risks |
What the National Academies concluded
At FDA's request, the National Academies reviewed compounded bioidentical hormone therapy and concluded there was a lack of rigorous evidence of safety and effectiveness from well-designed, properly controlled clinical studies. [6] Its report found insufficient evidence to support the overall clinical utility of compounded bioidentical hormones for menopause and male hypogonadism symptoms. [3] It did leave room for specific cases, such as an allergy to an ingredient in an FDA-approved product. [3] It also said patient preference alone should not determine use. [3]Questions to ask any prescriber
- Is there an FDA-approved version that meets my needs? If not, why?
- What is the evidence for this product, dose and testing plan for my situation?
- Who makes it, and who oversees that pharmacy?
- Does the clinic or prescriber sell the products, and how is that disclosed?
- What follow-up and stopping plan is in place?
Who may prescribe hormones depends on local rules, which the sources we read do not list; check with your state or country's licensing board. See bioidentical hormones in integrative practice, saliva hormone tests and testosterone and low testosterone.
Frequently asked questions
What does "bioidentical" mean?
It means a hormone with the same structure as one the body makes. FDA has approved drugs containing such hormones. [1] The question is whether a compounded version has been shown to be safe and effective.
Are compounded bioidentical hormones FDA-approved?
No. FDA says compounded drugs are not FDA-approved and it does not verify their safety, effectiveness or quality before they are marketed. [4]
Are bioidentical hormones safer than regular hormone therapy?
FDA does not have evidence that they are. [1] The National Academies found insufficient evidence for their overall clinical utility. [3]
Does "hormone balancing" treat fatigue, weight or mood?
We did not find a source that defines "hormone balancing" as a diagnosis or supports it as a treatment. Fatigue, weight and mood changes have many causes, so see a clinician. [2]
Is menopausal hormone therapy itself unsafe?
Not categorically. The North American Menopause Society says benefits and risks vary with the type, dose, timing and person, and treatment should be individualized. [5]

Risks and who should check first
FDA says compounded drugs should only be used when a patient's medical needs cannot be met by an FDA-approved drug. [4] State boards of pharmacy generally oversee day-to-day compounding pharmacies that are not registered as outsourcing facilities. [4]
