Best NMN Supplements of 2026, Ranked by Dose on the Label
Nicotinamide mononucleotide is sold at anything from 125 mg to over a gram per serving, and the label is the only place that number is stated consistently. These are ranked on the amount each brand filed with the NIH.
Before you buy NMN: the FDA has an open position on it
The FDA has taken the view that NMN is excluded from the definition of a dietary supplement, because it was authorised for investigation as a new drug before being marketed as a supplement. The agency said so in letters to manufacturers in 2025 and repeated it in new dietary ingredient responses in December 2025, and NMN is not listed in the agency's dietary ingredient directory as of 2026. NMN is still widely sold, and the FDA has not removed it from the market, but the position is unresolved. Nicotinamide riboside is not affected by this.
How this list was put together
Every product here is in the NIH Dietary Supplement Label Database, which means the manufacturer filed its label with the National Institutes of Health. The ranking is the amount of the active ingredient that the filed label states per serving, highest first. That is a fact printed on the package, not an opinion about the product. Several products often state exactly the same dose, and a numbered list hides that: where two or more tie, the one whose filed label reports more detail is listed first, and the tie is marked.
Published NMN trials have mostly used 250 mg to 900 mg per day. There is a second thing to know about NMN that has nothing to do with dose, and it is covered below: the FDA's position on whether it may be sold as a supplement at all.

What a label cannot tell you
A label states a dose. It does not tell you whether the product contains what it says, how well it is absorbed, what it costs, or whether it works. Dietary supplements are not reviewed or approved by the FDA before they are sold, and no product here has been tested by Peptides.io. Peptides.io sells nothing and has no commercial relationship with any brand named on this page.
Frequently asked questions
Which NMN supplements has the highest dose per serving?
Nutricost NMN 1 g, at 1 g per serving according to the label filed with the NIH.
How many of these state at least 250 mg per serving?
8 of the 8 products listed here. That is the amount most published human trials of this ingredient have used per day.
How were these ranked?
By the amount of the active ingredient stated on the label each manufacturer filed with the NIH Dietary Supplement Label Database, highest first. No brand paid for a place on this list, and Peptides.io earns nothing from it.
Does a higher dose mean a better product?
Not on its own. A label states an amount, not whether the product contains it, how well it is absorbed, or what it costs. Dose is simply the one number every brand has to declare, which makes it the only basis on which all of these can be compared fairly.
