NAD vs NR vs NMN: What Actually Works? | Dr. Halland Chen on Detox, Brain Power & Healthspan | Ep. 82

Is NAD the ultimate “power wash” for your cells—and how close are we to mainstream stem-cell therapy in the U.S.? In this episode, Sam sits down with Dr. Halland Chen, PM&R physician, interventional spine specialist turned regenerative-medicine researcher—to unpack the science (and myths) behind NAD⁺, NR/NMN, NADH, and the fast-emerging world of autologous mesenchymal stem cells.Dr. Chen explains:Why he left procedure-heavy pain medicine for true healing and regenerationNAD routes & use-cases: IV vs subQ vs oral precursors (NR/NMN), where each shinesWhat IV NAD “feels like”, why rate & dose matter, and how pumps reduce side effectsNAD for detox (alcohol/opioids/benzos), inflammation, circadian rhythm & brain clarityThe rise of IV NR (shorter drips, intracellular boost) and stacking with NADHBiomarkers that actually help: methylation age tests, mitochondrial function (e.g., MeScreen), VO₂ max, grip strength, symptom trackingGLP-1 + NAD synergy for metabolism & healthspanThoughtful takes on methylene blue, red light, and “frequency” therapiesFlorida’s July 1 shift and what it means for stem cells in the U.S.Why autologous (your own DNA) + high-dose, small, non-sticky cells (~200M) can be a game-changer for neuro, ortho, and longevity use-casesThe real longevity edge: focus, consistency, data—and a mindsetTakeaways:Treat longevity like a season: pick 1–2 goals, track data, build routines.Use the right NAD modality for the job (detox vs cognitive vs daily support).Expect personalized protocols as research clarifies NAD metabolism and stem-cell dosing.Healthspan > lifespan. Write it down.
