Hosted by Dr. George Murphy, each episode dives into the rapidly evolving fields of aging biology, longevity, regenerative medicine, and geroscience. From cellular rejuvenation and advanced therapeutics to lifestyle strategies that build resilience against disease, we examine what the science actually shows—and what it doesn’t. No hype. No myths. Just rigorous, evidence-based conversations about how we can reprogram our biology to live longer and healthier lives.","last_synced_at":"2026-07-07T06:17:35.175675+00:00","page_url":"https://stenobird.com/podcast/the-reprogram-7585130"},"episode":{"title":"NAD and Aging: Did We Get the Story Wrong","slug":"nad-and-aging-did-we-get-the-story-wrong","published_at":"2026-05-18T16:00:00+00:00","page_url":"https://stenobird.com/podcast/the-reprogram-7585130/nad-and-aging-did-we-get-the-story-wrong","show_page_url":"https://stenobird.com/podcast/the-reprogram-7585130","url":"https://podcasters.spotify.com/pod/show/thereprogrampodcast/episodes/NAD-and-Aging-Did-We-Get-the-Story-Wrong-e3jflcj","audio_url":"https://anchor.fm/s/10b3944a8/podcast/play/120099667/https%3A%2F%2Fd3ctxlq1ktw2nl.cloudfront.net%2Fstaging%2F2026-4-17%2F424299595-44100-2-200b59ad1598e.mp3","summary":"ReProgram Episode 14 The NAD Myth? What the New Human Data Really Say 🧠 Episode Overview In this episode of The ReProgram, Dr. George Murphy takes a critical but balanced look at one of the most popular ideas in the longevity space:That NAD levels decline with age — and that boosting NAD may help slow aging.But new human data challenge one of the most common assumptions behind the NAD story:Whole-blood NAD levels may not decline with age.This episode explores what that finding means — and what it does not mean.The central takeaway:NAD is not dead.But the simplistic NAD longevity story needs a reset. 🔑 Keywords NAD, NAD+, aging, longevity, NR, NMN, NAD boosters, nicotinamide riboside, nicotinamide mononucleotide, mitochondrial function, DNA repair, sirtuins, PARPs, CD38, cellular metabolism, biological aging, healthspan, resilience, recovery capacity, inflammation, stress response, biomarker, whole-blood NAD, NAD decline, NAD supplements, NAD IV therapy, metabolism, cellular stress, anti-aging supplements, longevity science, The ReProgram Podcast 🧠 Takeaways • NAD is essential biology, but it should not be treated as a magic anti-aging molecule. • New human data challenge the idea that whole-blood NAD levels universally decline with age. • Raising blood NAD is not the same thing as proving that aging has slowed. • NAD biology is likely tissue-specific, disease-specific, stress-specific, and context-dependent. • Blood NAD is not necessarily a reliable window into NAD metabolism in muscle, brain, liver, immune cells, or other tissues. • NAD boosters like NR and NMN can raise NAD-related metabolites, but that does not automatically mean they improve healthspan or longevity. • The most honest current framing is that NAD boosters are biologically plausible, biomarker-active,…","meta_description":"ReProgram Episode 14 The NAD Myth?
