NAD+ and Your Mitochondria, Explained Without the Jargon

NAD+ — nicotinamide adenine dinucleotide, if you want to impress someone — is having a moment. Longevity podcasts mention it constantly. Biohackers swear by it. But what does it actually do?

Inside every cell of your body sit mitochondria: small organelles that take the food you eat and turn it into ATP, the energy currency your body runs on. That conversion is a multi-step chemical relay, and NAD+ is the molecule that ferries electrons from one step to the next.

NAD+ isn't energy itself. It's the carrier that makes energy possible.

Here's the catch. As you age, your NAD+ levels drop. By 60, the average person has roughly half the NAD+ they had at 20. Less NAD+ means slower, less efficient mitochondria. Less efficient mitochondria means lower baseline energy, slower recovery, and according to a growing body of research, accelerated aging at the cellular level.

IV NAD+ delivers the molecule directly to your bloodstream, where it's available for cellular uptake without the absorption losses that hammer oral supplements. The infusion is slow — usually 2–4 hours — because faster delivery causes uncomfortable flushing.

What clients tell us after a course of NAD+ sessions: sharper mornings, better workout recovery, and a noticeable lift in mental endurance through the afternoon slump. None of that is magic. It's mitochondrial function, restored.
