- 1.Only brands whose third-party certificate of analysis can be verified are eligible — publishing it beats supplying it on request, and that gap decides close calls.
- 2.Dose must fall inside the 250–2,000 mg/day range human trials actually tested. This matters more than it sounds: the Science trial noted typical commercial capsules hold 50–150 mg, well under what was studied.
- 3.Ties break on price per effective dose — the cost of reaching a studied dose, not the cost of a bottle.

NMN is graded B — promising. Multiple randomized human trials show real biomarker and functional effects, but no trial has measured disease outcomes or run longer than 10 weeks. Read the evidence before you spend anything.

Is a higher dose worth paying for?
Above 600 mg/day there is no published evidence of extra benefit — that is where efficacy peaked in the only dose-ranging trial. Higher doses have been tested for safety, not for effect. Paying for more is usually paying for marketing.
Powder, sublingual, or capsules?
Every positive human trial used ordinary oral dosing. No head-to-head study shows sublingual absorption translates into a better result, so choose on testing and price rather than format.
What does a certificate of analysis actually tell me?
That an independent lab verified the batch contains the dose on the label and passes purity limits. In a category with a documented history of underdosed products, it is the single filter that matters most.
Should I pick NR instead?
NR also raises NAD+ and has longer-running safety data. If you are in the UK or EU, where NMN is not authorised as a supplement, NR is the option that is actually legal to buy.
