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 regeneration NAD routes & use-cases: IV vs subQ vs oral precursors (NR/NMN), where each shines What IV NAD “feels like” , why rate & dose matter, and how pumps reduce side effects NAD for detox (alcohol/opioids/benzos), inflammation, circadian rhythm & brain clarity The rise of IV NR (shorter drips, intracellular boost) and stacking with NADH Biomarkers that actually help: methylation age tests, mitochondrial function (e.g., MeScreen), VO₂ max, grip strength, symptom tracking GLP-1 + NAD synergy for metabolism & healthspan Thoughtful takes on methylene blue , red light, and “frequency” therapies Florida’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-cases The real longevity edge: focus, consistency, data—and a mindset Takeaways: 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. Stick with it.
