NAD+ vs NMN vs NR: what the sellers we priced actually sell
NMN and NR are precursors: molecules the body converts into NAD+. NAD+ itself is the end product. That distinction is the whole of the popular comparison, and it is usually argued on absorption — whether an injected NAD+ molecule or an oral precursor gets more of the thing you want to where you want it.
This site cannot settle that, and does not try. What it can do is say what the market it priced is actually selling, because the answer is startling and nobody seems to print it. We read 376 NAD+ prices from 106 sellers on September 2026 and classified the route of administration of every one of them by hand. 1 of the 376 is an oral precursor.
What this roster is, and what it is not
The distinction matters because the honest finding here is narrow and the dishonest version is one word away. “Only one of the prices we read is an oral precursor” is true and checkable. “Almost nobody sells NMN” would be a claim about a market we did not read.
What these sellers actually sell
of the 376 prices in the roster
Counted from the route field, a closed enumeration of nine values decided by hand from the seller’s own printed words, in the roster read on September 2026. The bar scale is the roster total, so the empty space is part of the finding. Duplicated figures are included here because the question is how often each form is offered, not how many distinct prices exist.
Subcutaneous injection dominates, nasal spray is a real second tier, and intravenous infusion — the route the category is best known for — is 6 prices from 2 of the 106 sellers. IV NAD+ is famous and rarely priced in public; there is a page working through the ones that are.
The oral precursor is a single product from a single seller, and it is worth printing in full because it is the entire overlap between this roster and the NMN/NR question:
$32.95 — a one-time purchase, with no dose printed beside it.
$32.95 against a roster whose injected products run into the hundreds is exactly the price gap that makes the oral precursor question interesting, and it is also why the gap cannot be read as a bargain. The price states no dose, so there is no milligram figure to divide, and it is left off the cost-per-milligram board rather than estimated onto it.
Why cost per milligram will not settle this
This site exists to normalise NAD+ prices to a cost per milligram delivered, and that arithmetic is the right tool for comparing two injections. It is the wrong tool for comparing an injection with an oral precursor, and it is worth being explicit about why.
A milligram of injected NAD+ and a milligram of an oral NMN capsule are not the same quantity of the same thing. One is the molecule itself, placed under the skin. The other is a different molecule, swallowed, and the amount of NAD+ it eventually yields is a biological question with an answer this site has no way to establish. Dividing both by milligrams and putting the two numbers in one column would produce a comparison that looks rigorous and means nothing.
The route most prices do not state
There is a larger problem sitting underneath the NAD+-versus-precursor question, and it shows up the moment you try to sort this roster by form.

Prices a reader can actually see on the page
335 of 376 — 41 are in the markup only
Computed at build time from the roster read on September 2026. “States no route” counts the unspecified value of the route enumeration, which records the seller’s own silence rather than a gap in our reading. “States no dose” is an exact match against the corpus’s own sentinel string, not a pattern.
109 prices name no route. 250 state no dose. For a reader trying to decide between an injection and a capsule, a price that states neither is not a data point — and this is the single most common shape in the roster.
- subcutaneous injection (177)
- route not stated (109)
- nasal spray (46)
- sublingual or oral (26)
- intramuscular injection (7)
- IV infusion (6)
- topical (2)
- transdermal patch (2)
- oral precursor (1)
What we will not print
We also will not put an oral precursor and an injection in the same ranked column, and we will not name a cheapest anything. Where a price states enough to divide, the division is printed beside the answer so you can check it; where it does not, the price is left out rather than estimated in.
How the route of every price was decided
Route was typed by a person from the seller’s own words — a product name, a form description, an instruction — into one of nine values, and the wording that decided it is carried beside the classification wherever the seller supplied any. Where the seller said nothing that identified a form, the value is unspecified, which records their silence rather than our uncertainty.
⛔ It was not pattern-matched out of page text, and that is deliberate. A seller who also sells a nasal peptide will say “nasal spray” on a page whose NAD+ product is an injection, and a word-matcher cannot tell which product the phrase belongs to. Reading the page is slower and it is the only method that gets this right.

Does this mean NMN and NR are not worth buying?
No, and this page makes no claim of that kind. It says what 106 sellers of NAD+ pricing were selling on September 2026: overwhelmingly the molecule itself, by injection or nasal spray, with 1 oral precursor among 376 prices. A census of precursor sellers would be a different roster and we have not read one.
Can I compare an NMN capsule with an NAD+ injection on cost per milligram?
Not meaningfully. Cost per milligram is comparable within one molecule and one route. A milligram of a precursor is not a milligram of NAD+, and the conversion is a biological question this site cannot answer, so putting both in one ranked column would give a rigorous-looking number with nothing behind it.
Why do so many prices not say what form they are for?
109 of 376 prices name no route because the seller printed none near the figure. That is recorded as the seller’s silence, not guessed at from elsewhere on the page — a page can be selling several products, and inferring a form from a nearby word attaches the wrong one.
Where can I see the prices themselves?
The cost-per-milligram board lists every price in this roster that states enough to divide, with its route, its billing cycle in the seller’s own words, and the arithmetic printed underneath. The sellers that publish nothing divisible are named there too, as a count.
