The NAD+ precursor the FDA banned, then un-banned on a technicality.
Every offer, cheapest per milligram first
Vials come in different sizes, so price per mg is the only column that compares like with like.

4 of 8 offers have something about the listing worth knowing.

Vendor by vendor
What each site was showing when we read it, and how it prices against the rest.
Three things price per mg does not tell you
A cheap milligram is only cheap if the vial holds it.
The label is a claim, not a measurement
Every per mg number here divides the price by the milligrams printed on the vial. Testing labs regularly find vials that weigh less than the label says.
Shipping and card fees are not in these numbers
Shipping is often flat, so it hurts small orders most. Several vendors add a card fee and discount for crypto. Two offers a dollar apart can swap places at checkout.
Bigger vials look cheaper and go off just as fast
A bigger vial costs less per mg and expires on the same schedule. Once mixed, most people work to about 28 days in the fridge, so the saving only counts if you finish it.
How wide the price gap really is
Same compound, same buyers, very different tickets.
Ignoring the few freak listings at each extreme, the dear end of the NMN market costs 2.4 times what the cheap end does, per milligram.
Half these listings charge more than this per mg and half charge less. It moves with sales, which is why every row carries a date.
Enough coverage to show a real range. Anything under three vendors stays off the hub.
What you are actually buying
Regulatory status changes what a price means.
Supplement
The status flipped twice and the second flip turned on the reading of a single word. In November 2022 the FDA told NDI notifiers that NMN was excluded from the definition of a dietary supplement, because it had been authorised for investigation as a new drug, MIB-626, before being lawfully marketed as a supplement. In its response to citizen petition FDA-2023-P-0872 the agency reversed that. It did not change its view of the facts. It changed its reading of the race-to-market clause, deciding that the earlier supplement marketing does not have to have been lawful to count. Since NMN was on sale in the US as a supplement as early as 2017, before the drug authorisation, it wins that race and is no longer excluded. The FDA also conceded in the same letter that its original searches missed the connection because staff reviewing the notification did not realise MIB-626 referred to NMN.
Full NMN record →Nobody stands behind a research vial
There is no pharmacist behind it, no dispensing record, and nobody on the hook for what is inside. The lab report is the whole quality system, which is why it sits next to the price here.
Research use only is a claim the seller has to keep making. A vendor that adds dosing instructions, health claims, or personal-use wording has stepped outside the framework it relies on, and that says something about the seller.
What customs and carriers do varies by state and by shipper. This describes how these products are sold and is not legal advice.
Before the vial arrives
What actually shows up, and the vial maths that decides which size is the better buy.
Frozen dry, refrigerated wet
Freeze-dried powder keeps for a long time in the freezer and for months in the fridge. Once liquid goes in, most people work to about 28 days in the fridge, away from light.
Bacteriostatic water and insulin syringes are extra
What arrives is powder in a sealed vial. Water goes down the inside wall rather than onto the powder, and the vial is swirled instead of shaken. Neither the water nor the syringes are in the prices above.
The bigger vial is only cheaper if you finish it
A larger NMN vial costs less per mg and expires on the same schedule once mixed. The saving is real only when the vial runs out inside that window.
Nothing on this page tells you what to take. Full walkthroughs live in the guides.
How this table is built
What decides the order of the rows, and who gets to be in them.
Cheapest per mg first, and nothing else
Rows sort on one number. There is no combined score and no weighting, so no vendor can be pushed up the table by a rating you cannot check.
Doing badly does not get a vendor removed
Vendors that publish nothing stay in the table, marked. Taking them out would make the market look tidier than we found it.
Every price has a date on it
Prices are read off public catalog pages and saved with the date. If a check runs late the row says so instead of showing an old price as current.
Sorting never reads who pays us
Commissioned links are marked on the row and listed on the disclosure page. They never move a listing up or down the table.
How these prices are collected
Prices on this site are read from vendor websites on the dates shown. A starting tag means the vendor publishes only a from price for that product. A wall means the vendor hides prices behind a login, and we publish that fact rather than hide the gap.
We report prices and never rate or score an offer. There is no value grade, no ranking of vendors by our opinion. A row carries its size, its price, its price per milligram, and any plain fact about the listing worth knowing.
When a vendor's site disappears, its rows stay in the tables as a dated record, drop out of every count, price range and ranking, and lose their links. Sixty days after a vendor's site disappears, its rows leave these tables and remain in our records.
Some vendors pay this site a commission when you buy through our links. Every one of those links is marked, and every vendor with that arrangement is labeled on the vendor page. Commissions never change the prices we show, the order of any table, a vendor's badge, or anything in the audit record. The data is collected the same way for every vendor, paid or not.
We accept no payment for coverage, placement, or ratings. Warning letters come from fda.gov. If a paying vendor earns a bad mark, the mark stays.
Questions about buying nmn
Cost, sizes, and how this table works.
How much does nmn cost?+
Across 4 vendors it typically runs $0.25 to $0.60 per milligram, with the cheapest sticker price at $34.99. Prices exclude shipping, card fees, and bacteriostatic water.
Why is the same vial so much cheaper at one vendor?+
Vial size, sale cycles, payment method discounts, and how much testing evidence a seller publishes all move the number. A cheap milligram is only cheap if the vial holds what the label claims, which no price column can tell you.
Do you make money if I buy?+
Sorting never reads whether a vendor pays us. Any commissioned link is marked on the row and listed on the disclosure page, and it never changes where a listing lands in the table.
Is nmn legal to buy?+
The status flipped twice and the second flip turned on the reading of a single word.

How current are these prices?+
Every price is read off a public catalog page and stored with its date; this compound was last read Aug 28, 2026. Nothing is overwritten, so a stale row says so rather than pretending to be current.
