Our Story
Why this exists.
A short catalogue, one molecule, and a set of decisions that all point the same way. This is what those decisions were and why we made them.
The shelf was already full
NAD+ is not an obscure ingredient. It is on the front of a lot of bottles, and almost none of those bottles contain it. They contain a precursor, something the body can build NAD+ from, because NAD+ itself is a large fragile molecule and most of an oral dose is taken apart long before it reaches a cell. That is a reasonable approach and it is not the same thing, but the labels rarely make the distinction.
So the form followed the molecule
Once you take the delivery problem seriously, the product stops being a bottle. It becomes a freeze-dried vial, a cold parcel, a device to deliver it and the consumables that go with the device. Everything in the box exists because of one property of one molecule, which is also why we sell it as a kit rather than as four things you assemble yourself.
Three things, and nothing else
The catalogue is a kit and the two parts of it that run out. It would be easy to add a capsule, a powder and a topical, and every one of them would dilute the only claim we can defend. We would rather sell a short list we can stand behind than a long one we cannot.
The certificate goes in the box
Every batch is measured by an independent laboratory before it ships, and the certificate travels with it rather than arriving on request. The purity printed on it is that batch's own result, not a specification it was expected to meet. It is the one number on this site anybody can check, so it is the one we put in the customer's hands.
And we say what we do not know
Research on NAD+ is active and a good deal of it is early. There are no customer photographs on this site, no average rating we have not earned, and no returns promise invented to fill a gap. Being specific about the limits is not a caveat we are obliged to print. It is the reason to believe the rest.
The Science
The long version.
What NAD+ does in a cell, what happens to it as you age, why the route matters, and what the evidence does not yet support.
