What does bioidentical mean?
Bioidentical hormones are structurally identical to hormones the body produces. The term can apply to ingredients in FDA-approved medicines as well as compounded preparations. It therefore does not identify one standardized product or one kind of treatment.
When someone recommends bioidentical hormone therapy, ask for the active ingredient and exact product name. Is the recommendation for estrogen, progesterone, testosterone, or a combination? What symptom or diagnosis is each ingredient meant to address?
Keep the answers together in your notes. A recommendation becomes easier to evaluate when you can name the proposed medicine instead of repeating a broad category from an advertisement.
FDA-approved and compounded are different questions
FDA-approved medicines undergo review for safety and effectiveness for their approved uses. A compounded preparation does not become FDA-approved because it contains an ingredient also used in an approved drug. FDA advises using approved menopausal hormone options and has not established that compounded bioidentical products are safer or more effective.
Ask whether a commercially available approved medicine could meet your needs. If a compounded preparation is proposed, ask what specific reason makes it appropriate in your case and which uncertainties should be considered.
The useful comparison is between named products, doses, routes, and intended uses, not simply a natural-versus-synthetic slogan. Bioidentical, compounded, and FDA-approved describe different properties; they are not interchangeable categories.

Ask what supports the claims being made
Claims such as safer, better absorbed, or tailored perfectly should lead to questions about the evidence for the exact product and use. Ask whether the claim comes from a comparative study, a laboratory measurement, or patient stories, and what it does not establish.
FDA's summary of the NASEM review describes a lack of rigorous clinical evidence supporting compounded bioidentical hormone therapy's claimed safety and effectiveness. Experience shared by a friend may be meaningful to that friend, but it cannot establish your expected benefit or risk.
Ask the clinician to explain both what is known and what remains uncertain. You do not have to choose immediately when the answers are unclear, or when you want another clinical opinion.
Keep the delivery method separate
The word bioidentical does not tell you whether a medicine is swallowed, applied to skin, used vaginally, injected, or implanted. Ask about the actual route, instructions, side effects, and how the plan can be changed.
ACOG advises against routine compounded menopausal hormone therapy when suitable FDA-approved options exist. If pellets are part of the proposal, specifically ask about alternatives and the implications of a longer-lasting implant.
Also ask for the complete expected cost. Product price, placement procedures, laboratory work, and ongoing appointments should be understandable before you compare one approach with another.
Compare hormone delivery methods →Use four questions at the consultation
What exactly is in the proposed treatment? Why is it being considered for my concern? What evidence and approval status apply to this product and use? How will benefits, side effects, and the decision to continue be reviewed?
Record the exact ingredient and product, the clinical purpose, its approval status, and how treatment would be reviewed. If those details are missing, the word bioidentical has not given you enough information to make an informed choice.
