87 of the 230 NAD+ pages we opened published no price
The boards on this site are built from 143 pages that published a NAD+ price. They were not the only pages opened. 230 readings were taken across 122 sellers, and 87 of them produced nothing a price could be read off. That is the single most common outcome of opening a NAD+ product page, and it is invisible everywhere else on this site.
What the silence is made of
all 230 page readings
- 143 of 230 priced something
- at least one figure a reader could decide, with its qualifier and its route attached
- 43 of 230 showed no dollar amount
- the page rendered and simply does not put a number in front of a reader
- 23 of 230 money, not a NAD+ price
- the page rendered and showed dollar amounts, but they belong to something else — a different treatment, a shipping line, a membership
- 21 of 230 did not render for us
- a challenge screen, an empty shell, or a page that never finished loading — recorded as undetermined, never as a seller publishing nothing
Every page opened for this site, read September 2026. The bands partition the readings; each page falls in exactly one.
The last band is ours, not the seller’s, and it is the one worth being careful about. 21 readings came back with too little text to judge anything. That is recorded as undetermined rather than as “no price”, because a page we could not read is not a page with nothing on it. None of those 21 is counted anywhere on this site as a seller publishing nothing.
22 readings failed to render in total, not 21. The difference is a single page that failed on the first attempt and gave up a price on a slower re-read, so it sits in the first band above. Both numbers are printed because the smaller one alone would describe our success rate rather than the market.
19 of them were not about NAD+ at all
19 of the 87 silent readings never used the word NAD, in any form, anywhere in what a reader sees. These are pages a NAD+ link on the seller’s own site led to: category pages, redirects that landed somewhere else, and one address that returned a 404.

The one signal that predicted it in advance
Which page to open was decided before any of them was opened, from links the seller’s own site published. Where the only NAD+ link available looked like a blog post or an intake form rather than a product page, the reading was marked as a weak target at that point — a prediction, made in advance, that it probably would not carry a price.
It was right. 3 of the 19 weak targets produced a price. 140 of the 211 other readings did.

The weak flag is set by the target-selection pass on any URL whose path looks like a blog post or an intake form. Computed over all 230 readings, September 2026.
Which sellers this leaves with nothing
A silent page is usually not a silent seller. 69 sellers had at least one reading that produced nothing, and 49 of them priced something on another page. Up to three NAD+ pages were read per seller — the distribution is 34 sellers had 1, 68 sellers had 2, 20 sellers had 3 — so a seller with one silent page usually had a second page that worked.
20 of 69
sellers with a silent page priced nothing on any page we read
30 of 136
sellers we set out to price published no figure we could use
106 of 136
sellers reached the roster the boards are built from
30 of the 136 sellers this research set out to price ended with no usable figure — which is why the boards carry 106 companies and not 136. Every one of those 30 was pursued further rather than dropped: the walk one click past a silent page is what happened next, and it is its own page because the answer is not the one you would expect.
What this does and does not show
This is not medical advice. Nobody here is a clinician, this site runs no clinical review, and none of it should be read as a recommendation to take or avoid anything. Decisions about NAD+ belong with a licensed clinician who has your history in front of them.
The other 15
- NAD+ injection side effects
Which questions are worth asking depends on the route, and on whether the seller states a dose at all.
- NAD+ IV vs injection
A per-session price and a per-month price are not comparable until you have the milligrams for both.
- How often you take NAD+
Frequency is usually a billing cadence before it is a clinical one. Here is how to tell which you are looking at.
- The nine routes
NAD+ is sold nine ways and a third of the sellers on this roster name none of them. The whole census, both denominators, and what our reading had to move.
- “Route not stated”
The second largest group on the roster is the sellers who did not say. Some wrote nothing; others wrote a sentence that still is not a route. Every one of those sentences.
- Sublingual NAD+ and precursors
Two different molecules are sold under one word. Our own reading pass filed 18 of 26 on the wrong side of it before review.
- What a NAD+ price includes
Most figures never say what is in the number, and whether a seller tells you depends on the route. What this roster can say, and the one thing it cannot.
- NAD+ price by route
Is the spray cheaper than the injection? Fifteen sellers price both, and they do not agree with each other.
- Sellers that sell NAD+ more than one way
A brand offering NAD+ two ways is offering two purchases at two prices. How many do, which routes travel together, and how many never say.
- Who states the milligrams
A price without a dose is not comparable. The nasal sellers state milligrams more often than the injection sellers do, and the routeless figures state them least.
- How a route is billed
Not one figure for the two routes that need a clinic is a standing monthly rate. Sublingual is the weekly route. What kind of number each route publishes.
- When the URL names a route
A seller's own address is the first route claim a buyer meets. “Nasal” meant nasal every time. “Oral” never once meant the precursor a reader would expect.
- Prices in the markup
Most NAD+ pages carry dollar amounts you are not shown. Why that is a reason to open the toggles and not an accusation — with the control that bounds it.
- The price behind the intake
“They don’t publish a price” is only honest if you clicked the button. Thirty-three sellers were followed one click past the page. Almost none of it was a price.
- Pages that price two routes
Where a spray and a needle are sold in one grid, a route choice looks like a price choice. Which routes get sold side by side, and how deep it goes.
