NAD+ has become the longevity industry's favorite molecule, sold as as a supplement and as a four-hour IV that promises sharper thinking, more energy, and slower aging. But a new 2026 paper complicates the very story it was built on. In this episode, Jeff breaks down what NAD+ actually is, what the human trials really show, and why the gap between a $40 oral supplement and a $1,200 IV drip matters more than the marketing admits. You’ll learn about: What NAD+ does in the body and why it got tied to aging The new research questioning whether NAD+ truly declines with age Oral NR and NMN versus IV infusions, and what the evidence supports The risks rarely mentioned, including the cancer question Why the saline, B vitamins, and forced rest may explain how good people feel This episode is for anyone weighing NAD+, longevity supplements, or an IV drip, and who wants to tell real science from wellness hype first.
