The One Thing That Makes a Big Difference After 40 l Dr. Amy Killen l Ep #382

About this video

Niddam talks with Dr. Amy Killen about hormone health for women in perimenopause and beyond. Killen traces her focus on hormones to her mother’s hip fracture, which she links to women leaving hormone therapy after early Women’s Health Initiative headlines, and she argues those headlines missed nuance. The conversation covers bioidentical progesterone, testosterone options for women — presented as highly individual, with monitoring because some side effects Killen lists can be irreversible — and training for strength, flexibility and balance. A second theme is iron: Killen argues ferritin has a sweet spot, with too little linked in her account to shedding and fatigue and too much potentially interfering with estrogen’s effects.

Key takeaways

• Revisit old study headlines in context — Killen argues early hormone-therapy reporting shaped decades of avoidance
• Testosterone for women, in Killen’s framing, is an individual decision with monitoring, not a target number to chase
• Ask about ferritin, not just iron, when hair, energy or sleep change — and consider both low and high ends
• Train for balance and flexibility as well as strength, since falls and fractures drive much of the risk Killen describes
• Hormones work as a system in this account, so changing one in isolation may miss the picture
