41 NAD+ figures a reader never sees
376 figures from 106 sellers, read September 2026. Written September 2026.
A price can exist in a page without being on it. 41 figures in this index were read out of markup a browser never draws — structured data, hidden variants, fragments of a plan table that renders somewhere else — and every one of them is recorded and none of them is treated as a published price.
Visible text, or it is not published
A web page is two things at once: what a browser draws, and the file it drew it from. The file routinely contains prices the drawing does not — structured data written for search engines, product variants a shop keeps for its cart, fragments of a plan table that renders somewhere else on the site, markup left behind by an earlier version of the page.
Every one of those is a real number in a real file served by a real company. None of them is a price a reader was offered, and this index does not treat them as one.
How many, and which sellers
41 of the 376 figures in this index are in that category, from 17 sellers. They are not evenly spread: 12 of them belong to one seller, and most of the 17 contribute one or two.

Read the top bar carefully. The largest group is not junk or leftovers — they are standing rates and prepay totals, which is to say they are exactly the figures that would have been most useful if a reader could see them.
The clearest case: a price that appears nowhere on the page
The clearest case is a price that appears nowhere on the page at all.
| Seller | What was found | How this index treats it |
|---|---|---|
| HealthSource | A price of $370.00 in the page’s structured data, with no cycle and no wording of its own | Recorded and marked unresolved. The prices HealthSource shows a reader on that page are different numbers, and no reader ever met this one |
| HealthOn | “$350 per month” | Recorded as present in the markup only. It is a standing monthly rate by shape, and it is not counted among the ones this site publishes |
| HealthOn | “Nad + InjectionsStarting at $150 /mo*” | A floor, in the markup only. The visible floor on the same seller is a different figure |
The rule behind all three rows is one sentence: visible text, or it is not published. A figure a reader cannot see is not a price a reader was offered, however real it is in the file.

A shop serving a variant price in structured data is doing something completely ordinary. What makes the first row interesting is the gap: the figure a search engine could read off that page and the figures a person could read off it are different numbers, and only one set was ever offered to anybody.
Why they are recorded rather than dropped
The alternative to recording them would be to drop them, and dropping them costs more than it saves. A figure found and discarded leaves nothing behind: the next person to read the same page finds it again, cannot tell whether it was considered and rejected or simply missed, and has to make the judgement over from scratch.
Keeping them also makes the judgement checkable. Every markup-only figure is on its seller’s review page, marked as what it is, beside the figures that were visible. A reader who disagrees with the call can see exactly what was excluded and why — which is not possible for a number that was quietly deleted.
What this page cannot tell you
It cannot tell you where on a page a visible figure sat. The judgement recorded here is visible or not visible, not hero or plan card or comparison table, so a reader has to take the call itself on trust rather than checking the reasoning behind it. That is the largest gap in this index’s record of its own method.
It also cannot tell you what a seller intended. A price left in a feed after a change, a variant a shop never listed, and a deliberate cloak all look identical from outside, and this page does not distinguish between them because nothing in this index can.
Where on the page did a figure sit? This is the basis of the judgement that separates a published figure from one present only in the markup, and it is currently recorded as a yes-or-no rather than as a location.
A reading pass that records the surface each figure was read from — a hero, a plan card, a comparison table, a structured-data block — as a field. The publication judgement would then be checkable rather than merely stated.
About this page
Nobody at this site holds a medical license and nothing here is medical advice, diagnosis or treatment. This is a price index; the pages like this one exist because a reader cannot judge a price without knowing what the thing is. Talk to a licensed clinician before starting or stopping anything, and see the medical disclaimer.
Every count above is computed from this index’s own reading of 106 sellers’ pages, described below, and is recomputed each time this page is built — so it cannot drift from the tables and the reviews it is drawn from. If something here is wrong, the corrections page says how that gets fixed and what has been fixed before.
Where these figures come from
Every count on this page is computed, at the moment the page is built, from this index’s own record of what 106 NAD+ sellers publish about their prices: 376 figures in all, 344 of them distinct once 32 repeats of the same offer on a second surface are set aside, and 41 of them present only in a page’s markup rather than visible to a reader. Nothing here is typed into the prose, so a count in a sentence and the same count in a table cannot disagree.
All 376 figures were read on one day, September 2026, and there is no second reading. That is the standing limit on this page and on every page like it: nothing here says a price rose, fell or held, because nothing here has been measured twice. 7 of the 376 carry a flag saying they need reading again before they are relied on, and the reviews of the sellers concerned say which and why.
Each seller has a review page of its own listing every figure this index holds for it — the figure as the seller printed it, what kind of figure it is, the seller’s own words for the billing cycle, the day it was read and the address of the page it was read from. That is the trail from any number on this page back to a sentence a company published.
