What the trials used. What the label delivers.
Most supplement pages tell you what an ingredient does. Almost none tell you how much of it you are actually getting, or what dose the studies behind the claim actually used.
That gap is the whole point of this site.
Take a real example. A label reads "Fenugreek Seed Extract [2% Trigonelline] — 300 mg". That looks like 300 mg of an active compound. It is not. Two per cent of 300 mg is 6 mg of trigonelline. The rest is plant matter. Nothing on the label is false — the arithmetic is simply left to you, and almost nobody does it.
We do it, for every ingredient, and publish the result next to what the human trials actually used.
What we found first
We started with NAD+ and cellular longevity, because it is where the marketing has run furthest ahead of the evidence. One number from that work:
250 mg of niacinamide — a real, established NAD+ precursor — costs about US$ 0.04 per day bought on its own. Products in the NAD+ category charge 29 to 84 times that.
Some of that premium buys real things: a second precursor, a polyphenol at a dose that was actually studied, third-party testing, convenience. Some of it buys 1 mg of resveratrol in a formula whose marketing is built on resveratrol. Telling those apart is work, and it is the work this site does.
How to read us
We have not tested these products. We are not a laboratory and we do not pretend to be one. What we do is read the label, read the studies the label cites, redo the arithmetic, and show you both numbers side by side — including when the answer is inconvenient for a product we earn a commission on.
If that sounds narrow, it is. It is also the part nobody else publishes.
- How we work — the evidence grades, the dose calculation, and the ten checks every page passes before it goes live.
- Who writes this — one person, named, with an honest account of what he is and is not qualified to say.
