Can a Pill Make an Aging Runner Faster?

Can an NMN supplement really make you run faster after menopause? I started taking NMN and resveratrol after hearing Harvard scientist David Sinclair tell a story on a longevity podcast, and what happened to my running data did not fit anything I’d expect as a physician.In this episode, I share my own timeline honestly: a personal record at the Boston half-marathon, then menopause, a broken ankle, and eighteen months of detraining at fifty-five. Then, about four weeks after starting NMN and resveratrol, I was running faster than my lifetime baseline at a heart rate fifteen beats per minute lower. I can’t prove the supplements did it, and I won’t pretend to. Instead, I walk you through what the science actually says about NAD+, mitochondria, and healthy aging, including the famous “marathon mouse” study, the human trials in postmenopausal women and runners, and the real controversy around resveratrol’s bioavailability. We also talk about why so much of the NMN supplement market is mislabeled, and the lab tests I’d want before starting.In this episode you’ll learn:* Why NAD+ levels decline with age and what that means for energy and metabolic health* How NMN may improve insulin sensitivity and exercise performance in postmenopausal women* What the research on resveratrol and David Sinclair’s longevity claims really shows* Which labs to check before and after starting NMN, including homocysteine* Why third-party testing matters when choosing an NMN supplement* Why resistance training, protein, and sleep still matter more than any capsuleDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/can-a-pill-make-an-aging-runner-fasterCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
