How Biest Capsule works
Biest is a blend of two bioidentical estrogens: 20% estradiol and 80% estriol.
Estradiol is the more potent estrogen that relieves hot flashes and protects bones.
Estriol is a gentler estrogen that's considered safer for long-term use.
Together they provide effective menopause symptom relief with a more balanced hormonal profile than estradiol alone.
Bioidentical means it's chemically identical to the estrogen your body naturally makes.
What Biest is
A compounded bioidentical preparation. FDA has raised concerns specifically about marketing compounded hormone preparations as safer or more natural than approved products. We do not make that claim, and you should be sceptical of anyone who does.
Two estrogens, in a set ratio
Estriol and estradiol combined. Because it is compounded rather than a fixed commercial product, your provider can set the ratio.
Estriol has no approved product
Estriol is not a component of any FDA-approved drug in the United States.
Not FDA-approved
Compounded Biest is not an FDA-approved drug product and FDA does not review it for safety, effectiveness or quality.
Prescribed with monitoring
Your provider decides the ratio, the strength and what monitoring goes alongside it.
Biest Capsule questions
Is this safer than conventional HRT?
We will not tell you it is safer. "Bioidentical" describes molecular structure — the molecule is structurally identical to the one your body makes — and it is not a statement about safety or effectiveness. Compounded preparations are not FDA-approved drug products, and FDA has raised specific concerns about compounded hormone therapy being marketed as a safer or more natural alternative to approved products. Your provider will go through the actual risks and benefits with you.
