If you've researched NAD⁺ for more than ten minutes, you've hit the fork in the road: some protocols infuse NAD⁺ itself, others use nicotinamide riboside (NR) — best known by the brand name Niagen. Both claim the same destination. The difference is worth understanding, because it changes the session, the feel, and possibly the fit for you.
Finished product vs. ingredient
The analogy that actually holds up: NAD⁺ is the finished meal; NR is the groceries. Infuse NAD⁺ and you're delivering the working coenzyme, ready for immediate use. Infuse NR and you're stocking your cells' pantry with the precursor they use to synthesize NAD⁺ — each cell converting on its own schedule, through its own regulatory machinery.
That difference sounds academic. It isn't:
- Direct NAD⁺ — immediate availability, but the infusion must run slowly (the molecule can produce warmth or flushing if rushed), so sessions are longer. The choice for members who want the most direct intervention.
- NR (Niagen) — a gentler, typically more comfortable infusion, with the conversion step smoothing delivery into a gradual build. The choice for first-timers, sensitive responders, and maintenance rhythms.
Same destination, two on-ramps: one express and intense, one gradual and smooth.
Why infuse NR at all — aren't there pills?
NR capsules are the most-studied oral route in the category, and they're legitimate. But they still face the universal capsule problem: digestion takes its cut before circulation sees a milligram, and published work suggests meaningful losses on the way through. The Niagen IV exists to close that gap — the full NR dose, delivered to the bloodstream, conversion left to your cells rather than your stomach lining's mood.

The precursor route, minus the absorption tax.
Niagen $749
NR infused directly — your cells convert it to NAD⁺ on their own schedule. Gentler session, same destination.

How members actually choose
The pattern we see after thousands of sessions: start where your tolerance and curiosity meet. Members who want the flagship experience go straight to The Surge (direct NAD⁺ inside the full formula). Members easing into the category start with Niagen, feel the build over a few weeks, then decide whether to step up. Longtime members often alternate — direct NAD⁺ as the periodic deep restore, NR as the between-sessions maintenance layer.
There's no wrong door. The only genuinely wrong move, if you buy the biology, is the one most people default to: reading about the molecule for another year while running on less of it every month. Both roads come to your driveway — a registered nurse, physician-written protocols, anywhere in Palm Beach County.
