Understanding Progesterone: Myths, Science, and Health Impacts

Menopause Mastery Show | Understanding Progesterone: Myths, Science, and Health Impacts Progesterone in Perimenopause & Menopause: Bioidentical vs Progestins, Sleep, Cognition, and the Real Science Welcome to Menopause Mastery! Join Dr. Betty Murray in this episode as she breaks down the science behind progesterone. Amid online controversy, Dr. Betty explains what progesterone does in the body, how it declines first in perimenopause, and why bioidentical micronized progesterone differs from synthetic progestins used in birth control and older HRT like Prempro. She reviews evidence that oral micronized progesterone (often ~300 mg at bedtime) can improve sleep architecture and may reduce hot flashes/night sweats, while clarifying mixed findings and underpowered studies. It addresses brain and cognition claims by separating human data (largely neutral/no cognitive harm, mood benefits) from alarming animal studies, and explains individual variability via allopregnanolone metabolism, PMDD/depression history, genetics, and route of delivery (oral vs vaginal). In addition, she discusses cardiovascular nuance, endometrial protection with estrogen, and cyclical vs continuous dosing considerations. If you're a woman over the age of 35, and are looking for relief from hot flashes, night sweats, and disrupted sleep, this episode is for you.
