NAD+

Minimum order 2 vials or 2 pens — delivery in 2 weeks
The coenzyme that runs every redox reaction in the cell — and the fuel for sirtuins. It drops with age; the question is how you raise it.

It's not one supplement among many — it's the currency every cell uses to work.

NAD⁺ carries electrons in every redox reaction, and at the same time it's consumed by sirtuins and PARPs whenever the cell repairs DNA or regulates genes.

The number that exists in humans: in a pharmacokinetic study of a precursor molecule, a single dose raised blood NAD⁺ up to 2.7-fold, with a dose-dependent increase at doses of 100, 300 and 1,000 mg 1.

The honesty needed here: these data concern an oral precursor molecule, not injectable NAD⁺. The rationale for injection — bypassing the gut and liver — is reasonable, but it doesn't yet have pharmacokinetic evidence of its own.

The same study showed something useful too: NAAD works as a sensitive marker of whether repletion actually happened 1 — so there's a way to measure the result.

Unstable at neutral and alkaline pH — which is why proper preparations come with a buffer. Refrigerate, keep dark, use within a short window after reconstitution.

The currency of vitality inside you — and it can be replenished.

Every cell uses it to produce energy and repair itself — sirtuins, the guardians of cellular youth, need it to work.

And there's a number behind the promise: in a precursor study, a single dose raised blood NAD⁺ up to 2.7-fold, with an increase proportional to the dose 1.

The honesty, because it matters: this finding concerns an oral precursor, not injectable NAD⁺ — the rationale for injection is logical, but it doesn't have its own evidence yet.

Whatever you choose, at least you know there's a way to measure whether something actually happened 1.

A delicate molecule that deserves care: buffer, refrigeration, darkness, and use soon after opening — not something that sits in the fridge for weeks.

It's not a supplement. It's the currency.

NAD⁺ doesn't do one thing — it's the coenzyme that shuttles electrons in every redox reaction in the cell. And it's also a substrate: sirtuins and PARPs consume it to do their work. So every time the cell repairs DNA or regulates genes, it spends NAD⁺.

The human data, and exactly what they show. In the first clinical pharmacokinetic study of an NAD⁺ precursor in humans, blood NAD⁺ rose up to 2.7-fold from a single dose, and doses of 100, 300 and 1,000 mg produced a dose-dependent increase across the whole NAD⁺ metabolome 1.

And now the honesty we owe you, because it changes the interpretation: this study concerns an oral precursor — nicotinamide riboside — not injectable NAD⁺. The rationale for injection is that it bypasses breakdown in the gut and first-pass metabolism in the liver. It's a reasonable rationale. It doesn't have the same pharmacokinetic evidence, and we won't tell you it does.

A finding from the same study that's rarely mentioned and genuinely useful: NAAD proved to be a highly sensitive marker of real NAD⁺ repletion 1. In other words, there's a way to measure whether something actually happened — which doesn't exist for most “anti-aging” products.
