Bioidentical Progesterone: Why Every Postmenopausal Woman Should Know About This Hormone

Bioidentical Progesterone: Why Every Postmenopausal Woman Should Know About This Hormone

Progesterone is produced by the ovaries and plays a critical protective role in the uterus, breasts, bones, and cardiovascular system. After menopause — and often during perimenopause — production drops significantly, which can leave women without one of their most important protective hormones.

Like estrogen, the form of progesterone matters enormously. Synthetic progestins are not bioidentical progesterone.

The Synthetic vs. Bioidentical Difference

Synthetic progestins (like medroxyprogesterone acetate, sold as Provera) have been linked to breast cancer, strokes, heart disease, birth defects, weight gain, depression, bloating, fatigue, and even dementia. These are the risks that made the 2002 Women’s Health Initiative results so alarming — and they are specific to synthetic progestins.

Bioidentical progesterone, by contrast, has never been shown in any clinical study to increase the risk of breast cancer, stroke, or heart disease. In fact, it has been shown to reduce breast cancer risk.

We prescribe only bioidentical progesterone.

Benefits of Bioidentical Progesterone

• Protects the uterine lining (essential when estrogen is used)
• Reduces breast cancer risk
• Supports bone density and reduces osteoporosis risk
• Protects cardiovascular health (lowers total cholesterol, raises HDL)
• Reduces fibrocystic breast disease and ovarian cysts
• Can ease PMS and perimenopausal symptoms

Who Should Consider It

Every postmenopausal woman — with or without a uterus — should consider bioidentical progesterone. It is also beneficial for women in perimenopause or struggling with PMS.

Potential Side Effects

Bioidentical progesterone is generally well tolerated. Because it can cause mild drowsiness, it is typically prescribed at night — which many patients find beneficial for sleep. Other possible effects include breast or nipple tenderness, dizziness at high doses, and occasional spotting.

Who Should Not Use It

Pregnant women.

How We Prescribe It

Oral capsule or sublingual (rapid-dissolve tablet or triturate) are the most effective delivery methods. Topical creams and sublingual drops have poor absorption and are not recommended.
