Estrone Explained (Part 2): The “Forgotten Estrogen” and Why It’s Not the Bad Guy

Dr. Brendan McCarthy

In this episode — Part 2 of our Estrone Series — Dr. McCarthy takes a deeper dive into estrone, the often misunderstood and overlooked estrogen. Learn:

• Why estrone isn’t the “bad” estrogen it’s made out to be

• How body fat, inflammation, and lifestyle influence estrone levels

• The connection between estrone, insulin resistance, and breast health

• Why oral estrogen can worsen symptoms for some women

• Natural ways to support estrogen balance, including diet, nutrients, and detox pathways

Dr. McCarthy explains how understanding estrone can empower women through perimenopause and menopause — and why context and comprehensive lab work matter more than quick fixes.
