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 writes nadcost’s provider reviews and guides to NAD+ pricing, billing and consumer purchasing questions. nadcost is the publisher. Our comparisons are based on documented public information; they do not claim firsthand treatment experience or a clinical endorsement. Research guides link to the sources supporting their claims.

What you get here is pricing arithmetic: every figure with the month it was read, every division printed beside the number it produced, and the sum left out wherever a seller publishes only half of it. Nothing here is medical advice, and nothing here says whether NAD+ works or is right for you — take that to a licensed clinician who knows your history, and 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 reader-supported: when a reader follows a link to a provider and signs up, it may earn an affiliate commission. Keeping the calculator clean is what makes the pages that carry those links worth reading. The boundary is not a promise either: the calculator has no paid provider placements. How affiliate links and commercial placements work is explained on the disclosure page.
