About nadcost

What this site does

NAD+ is quoted per session, per month, per shipment and per bottle. None of those numbers are comparable until someone divides the price by the milligrams it buys, so this site does that division and prints it. Where the arithmetic is ours rather than the seller’s, it says so on the line where the number appears.

Who writes it

Tomas Lindqvist works in direct-to-consumer unit economics — the arithmetic underneath a subscription price. He built this site’s calculator because NAD+ is quoted per session, per month, per shipment and per bottle, and none of those are comparable until someone divides. He shows every division on the page. The calculator carries no advertising and never will; that is the point of it.

Tomas Lindqvist is a pen name. That is ordinary publishing practice and it is stated here rather than left to be discovered. What it is not is a hidden credential: he is not a physician, nurse, pharmacist or any other licensed clinician, and he does not review anything on this site clinically, because this site has no clinical review process and claims none. Nothing published here is medical advice — see the medical disclaimer.

Why the calculator carries no advertising

The calculator at /tools/nad-cost-per-mg carries no paid link, no sponsor, no promoted provider and no button that earns anything. It is the most useful thing on the site and it is the thing that earns least, and that is deliberate: a cost model sitting next to a button that pays its author is not a cost model, it is a sales page with division printed on it.

This site is paid by some of the providers it writes about, and the pages where that happens say so beside every link — the route explainers and the ranked cost table. Keeping the calculator clean is what makes those pages worth reading. The boundary is not a promise either: a build check walks everything the calculator imports and refuses to build the site if a paid link becomes reachable from it. The full accounting, computed rather than typed, is on the disclosure page.

Getting in touch

Corrections and questions go to editor@nadcost.com. If a price here is wrong, say which page and which figure — every one of them carries the date it was read, which makes it quick to check. Everything that gets fixed is logged on the corrections page.
