Products
A deliberately short list. What we have looked at, what we link to, and exactly how we get paid for it.
This page is short on purpose.
Most "best NAD supplement" lists rank fifteen products because fifteen affiliate programs accepted the publisher. That is not a ranking, it is an inventory. We list what we have actually looked at and are willing to put our name next to, and we tell you plainly where the money comes from.
What we check before linking anything
- The label states the active compound and the amount. If a product hides its dose inside a "proprietary blend," there is no way to compare it to anything, and no way to compare it to the research.
- The form is one with human data behind it. That means a recognised precursor in a format that has actually been studied in people — not a novel derivative supported only by cell-culture work.
- Claims stay inside what the evidence supports. Any product marketed as treating or reversing a disease is disqualifying, regardless of payout.
- No undisclosed warning-letter history. Where a brand has received an FDA warning letter, we disclose it on every page the brand appears on.
How we get paid, specifically
When you click a link marked "Paid link" and buy something, the merchant pays us a commission. You pay the same price either way. We do not take payment for placement, for a ranking position, or for a favourable write-up, and we do not accept free product in exchange for coverage.
The obvious objection is that a commission is still an incentive, and it is. Our answer is structural rather than moral: a comparison site that steers readers toward whatever pays most stops being useful within about a year, and the traffic goes away. The long-run incentive and the honest one happen to point the same direction here.
Aspen Health
Aspen Health sells an oral NAD+ supplement positioned around cellular repair, energy production and healthy aging — the mainstream use case, aimed at adults in roughly their mid-thirties and up who want a daily routine rather than a clinical procedure.
It sits in the category we think most people should start in. Oral capsules are the cheapest route per dose, the easiest to stay consistent with, and the format behind almost all of the human research worth citing. If you are new to this and want one decision rather than five, a daily oral product is that decision.
Check the current label and dose on the merchant's own page before you buy — formulations in this category change more often than publishers update their reviews, and ours is no exception.
Looking at the injectable route instead?
Injectable NAD+ is a different category with a different buying process, a different cost structure and different rules. We keep it on its own page rather than mixing it into a supplement list, because the two decisions are not comparable.

What is not on this page yet
We would rather list two products we have examined than twenty we have not. As we work through more of the category — sublingual formats in particular, where the quality spread is unusually wide — this page grows. It will never be a catalogue.
