Have you heard the terms “bioidentical hormones” and “body-identical hormones” and found yourself thinking, Hang on…aren’t they the same thing?
If you’re confused, you’re not alone. Even health professionals sometimes use these terms interchangeably.
Let’s clear it up.
Both licensed body-identical hormone therapies and compounded bioidentical hormone preparations are intended to use hormones with the same molecular structure as those naturally produced by the human body.
So what’s the difference?
The difference lies in the product, not the hormone molecule.
Licensed body-identical hormone therapies are manufactured to strict pharmaceutical standards. They contain consistent doses, undergo rigorous quality control, and have robust evidence supporting their safety and effectiveness. They are assessed and approved by medicines regulators before they reach patients.
Bioidentical isn’t a regulated term. It simply describes the hormone’s molecular structure, so it can refer to both licensed pharmaceutical products and compounded hormone preparations.
Compounded bioidentical hormones may have a role in very specific situations. But for most women, they are not recommended over licensed body-identical hormone therapy.
Although the hormone molecule may be the same, compounded preparations have not undergone the same rigorous evaluation for quality, consistency, safety and effectiveness as licensed medicines.
My advice? Don’t get distracted by marketing terminology.
Instead, ask:
“Is this a licensed, body-identical hormone therapy backed by evidence and safety data, and is it the right option for me?”
Women deserve clear, evidence-based information—not confusing terminology.
