NAD+ buying guide
“Starting at” is not a price, and 47 sellers publish one
“From $249.” After the monthly rate it is the most common shape of number on a NAD+ page, and it is the one that answers least: it names the smallest figure a seller is willing to print and says nothing whatever about the largest.
A floor is a lower bound with no ceiling
“Starting at $149/month.” The sentence contains a real number, and a reader can be forgiven for treating it as the complete price. The qualifying words make it a lower bound. They may leave the eligible configuration unresolved — which dose, which route, which term, on which plan — even when a condition is identifiable elsewhere.
86 of the 382 figures read for this index are that shape, from 47 of the 110 sellers. 79 of them are visible on the page a reader lands on; the rest were found in markup only. Every one of them is recorded with the seller’s own qualifying words attached, because “from $249” and “$249” are different facts and the difference is entirely in the wording.
The September 4, 2026 record in our PreventiveMD review shows a floor with an identifiable condition: the “as low as” monthly headline corresponds to a twelve-month supply plan. A separate one-month supply has a different figure. Check the full term and amount due before treating the headline as a month-to-month offer.
How many, and how many sellers publish nothing else
The September 4, 2026 record in our MangoRx review is a useful example: its starting monthly figure did not establish the administration route, strength, volume, or supply period. Ask which exact product and quantity the starting offer buys before treating it as comparable to a fully specified quote.
The number that matters more than 86 is 30. That is how many sellers in this index publish a floor and nothing else — no standing rate, no prepay total, no one-off price. For 30 of 110 companies, the most precise thing that can be said about what they charge is the smallest amount they were willing to print.
Those sellers are not hidden here and they are not ranked as though their floor were a price. The reviews hub groups all 110 by what kind of figure they publish, and the “from-price only” group is one of the seven. They are also, necessarily, absent from the dated price index, which plots only the 59 standing monthly rates from 43 sellers: a lower bound cannot be plotted against a median of charges.
Four floors whose own pages do not resolve them
A floor is at its most useful when the same seller publishes the range it is the bottom of. Four here do not, and each fails differently.
| Seller | The floor, in the seller’s own words | What the same seller also publishes |
|---|---|---|
| HealthOn | “From $110/month” | Four standing monthly rates on the same site — and $110 is not one of them, nor any other figure HealthOn publishes. The floor sits below everything it is a floor for |
| Bioverse | “Starting at $339 $259/mo” | Two figures in one sentence, with nothing saying which is current. Only the lower one is restated anywhere; the $339 is never labeled, so it goes down here as unresolved rather than as a former price |
| MadeMed | “From $279/mo.” | A second floor of $269 a month for a different product on a different page, and a standing rate of $269 a month billed as $1,614 every six months. Three figures, none of which reconciles the other two, all kept |
| InstaRX | “NAD+ Injection Starting at $265/Month *” | Nothing. This is the only figure InstaRX publishes in this index — no upper bound, no term, no dose |
None of these is a mistake by the seller. A floor is a perfectly legal thing to print; it is simply not a price, and a page that prints one has not told a reader what they will pay.
Source: Each row quotes the sentence printed around the figure, beside what else the same seller publishes. Read September 2026.
The HealthOn row is the one worth sitting with. Its floor is $110 a month, and no other figure HealthOn publishes anywhere in this index is that amount. Its four standing monthly rates are all substantially higher. The floor is therefore true in the narrow sense that nothing is cheaper, and useless in the sense a reader needs: it is not the price of anything on the page.
A floor across four products is not one product’s price
Some floors are excluded from this index rather than recorded as NAD+ prices, and the exclusions belong on this page as much as the inclusions do. A figure printed across a whole catalog — injections, creams, nasal spray and patches under one “from” — is a floor for a shop, not for a product. Neither is a multi-molecule program price, where the same figure covers NAD+ and something else.
What this page cannot tell you
It cannot tell you what any of these sellers actually charges. That is the point of the page: a floor is a published fact that does not contain the answer, and this index will not manufacture one by treating the lowest number as the price.
It also cannot tell you what is behind the floor. What dose 30 sellers’ lowest figure buys is unstated for most of them — 255 of the 382 figures here state no dose — and this site publishes no price per milligram. Read the figures on the boards and on each seller’s review for their individual reading dates. The latest recorded reading across the index is October 2026; it does not refresh the older observations.
What does a published price NOT include? What a seller says a price covers is recorded here; what it leaves out is not, so a shipping charge, a consultation fee or a required blood test can sit outside every figure on this site.
Someone reading each seller's page again and writing down, figure by figure, the exclusions and extra charges printed beside the price. Several are already known to exist — a flat shipping fee, a medical visit fee, a blood test required before prescribing — which is why the gap matters: those charges were seen and there was nowhere to record them.
When a seller prints two figures side by side with nothing linking them, which one is the price? Both figures are kept here, and nothing says the two are a pair or that they contradict each other.
A record of which figure goes with which, written down while the page is being read. It is a matter of shape rather than one more value: nothing here can hold a disagreement between two figures, which is why figures that disagree are marked unresolved one at a time instead of as the pairs they are.
For examples of the condition attached to a headline, the Arc-1 review records subscription starting prices and the Ascend Vitality review records starting prices across different formats. The ShedRx review also separates figures by product. A starting figure in any of these records is not a promise of the amount an individual buyer will pay.

About this page
Nothing here is medical advice, diagnosis or treatment. This is a price index, and 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 comes from reading 110 sellers’ own pages, and each one is worked out again every 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
These counts describe the recorded pricing information for 110 NAD+ sellers: 382 figures in all, representing 350 distinct offers after 32 repeat observations of the same offer are set aside. Of the recorded figures, 41 appear only in page markup, rather than visibly on the seller’s page.
Current source readings span September 2026 to October 2026. Each price retains the date of its own source observation. A latest source date does not mean that every provider was checked again then. Earlier price checks are retained for 14 of the 110 providers; their review pages show those readings separately. A source period alone does not establish that a price rose, fell or stayed the same.
Each seller has a pricing review showing recorded prices or quote status, original payment qualifications and source dates, including labels for figures found only in markup. We retain the underlying merchant source records internally. Reviews show the recorded pricing evidence and link through to the provider so you can confirm current terms.
