Key Fact
Micronized progesterone is chemically identical to the progesterone the body naturally produces and is generally considered to have a more favorable safety profile compared to synthetic progestins.
Price
$15 - $60/mo
Micronized progesterone is a key component of hormone replacement therapy for women who have an intact uterus. When estrogen is taken alone (without progesterone), it can cause the uterine lining to thicken, which may increase the risk of endometrial hyperplasia or cancer. Progesterone counteracts this effect by promoting regular shedding of the lining. Micronized progesterone is considered bioidentical because its molecular structure is identical to the progesterone produced naturally by the ovaries. It is generally well-tolerated and may also have mild sedative properties that can help with sleep when taken at bedtime.

How Progesterone (Micronized) Works
Progesterone works by binding to progesterone receptors in the uterine lining, counteracting the growth-stimulating effects of estrogen. This helps prevent endometrial hyperplasia — an overgrowth of the uterine lining that can occur when estrogen is taken without progesterone. Micronized progesterone is processed into tiny particles that improve absorption. When taken orally at bedtime, it is metabolized into allopregnanolone, a neurosteroid that may promote relaxation and improve sleep quality — a welcome side benefit for many menopausal women experiencing sleep disruption.

Who Is Eligible
Progesterone is prescribed primarily to women with an intact uterus who are taking systemic estrogen therapy. Women who have had a hysterectomy generally do not need progesterone as part of their HRT regimen. Progesterone capsules contain peanut oil, so women with peanut allergies should discuss alternative progestogen options with their provider. Women with a history of blood clots, liver disease, or breast cancer should discuss risks carefully before starting.
