Meet Dr. Amy

Welcome. I’m Dr. Amy Killen, MD.

Longevity physician, regenerative medicine pioneer, and fierce believer that educated women thrive through every phase of life.

I worked as a board-certified emergency medicine physician for ten years and witnessed what happens when we wait too long to care for ourselves. I left emergency medicine in 2013 because I wanted to intervene upstream, to help women stay vibrant, strong and sassy as hell as they navigate midlife and beyond.

Here, science meets soul and empowerment, and play is the prescription.

Longevity medicine was built for the other half.

The ovary is not a bystander in female aging. It is the pacemaker.

Most longevity advice was built on male biology and a lot of wishful thinking. Women outlive men in every country on Earth, then spend more of those bonus years feeling lousy, because medicine forgot to study us.

The book is the playbook. The course trains the doctors. The protocol is what I take myself. Start wherever you are.

What people are saying about the book

“Women outlive men but spend many of those years sick, dismissed, and under-researched. Dr. Amy Killen finally asks why, and the answer changes everything. The Female Longevity Advantage is the first longevity book that treats female biology as the design rather than the exception. It is rigorous, funny, and furious in all the right places. As a physician, I learned things here I was never taught in medical school. As a woman in her forties, I felt seen.”

Tiffany Moon, MDAuthor of Joy Prescriptions

“Bold, smart, funny, and packed with actionable advice. Every woman who wants to feel better now and age better for decades to come should read this book.”

Frank Lipman, MDNew York Times bestselling author of Age Better

“Smart, practical, irreverent, and refreshingly doable.”

JJ VirginFour-time New York Times bestselling author

“Women are not simply ageing versions of men. Every woman should read it.”

Louise Newson, MBChBGP, menopause specialist, founder of Newson Health

Female longevity isn’t about becoming ageless or chasing some impossible standard of perpetual youth. It’s about understanding your unique biological superpowers, protecting against your specific vulnerabilities, and optimizing for the life you want to live, with energy, clarity, sexiness, strength, and joy.
