How do you take NMN powder? In human trials, 250 to 900 mg of NMN a day raised blood NAD+

How do you take NMN powder, and how much? In human trials, 250 to 900 mg of NMN a day raised blood NAD+ (Morifuji 2024; Yi 2023). In a 60-day trial of 80 healthy middle-aged adults, NAD+ was highest at 600 and 900 mg, those groups walked furthest in a six-minute test, and blood biological age held steady on NMN while it rose on placebo (Yi 2023). Here is a routine built on what the trials gave participants: a daily amount inside the 250 to 1,200 mg they used (Liao 2021), once a day or split in two, in a form you can keep up, for 6 to 12 weeks. One 0.5 g scoop of NMN Pure Powder holds 500 mg. How much the NAD+ rise varies from person to person, and whether taking it under the tongue changes it over weeks, are the open points.

How people took it in the trials

The trials that tracked NAD+ over time gave NMN by mouth, every day, for 14 days to 12 weeks. Pick the form you can take every day.

The dose. The human trials most often used 250 to 900 mg of NMN a day. In a 60-day trial of 80 healthy middle-aged adults, 300, 600 and 900 mg a day each raised blood NAD+ versus a dummy pill, with the highest levels, and the longest six-minute walks, at 600 and 900 mg (Yi 2023). In a 12-week trial of 60 older adults, 250 mg a day raised blood NAD+ and its metabolites above placebo (Morifuji 2024). A 6-week trial of 48 amateur runners went up to 1,200 mg a day (Liao 2021). Across a 2025 meta-analysis of 12 studies in 513 adults, NMN significantly raised blood NAD (Zhang 2025).

The form. No trial in our evidence compared powder with capsules or liposomes, so the choice between them is one of convenience and value. The one trial that compared routes, a crossover in 14 healthy men, found that taking NMN under the tongue (sublingually) raised two NAD+ by-products (2PY and 4PY) faster over the first 60 minutes than swallowing it, while blood NMN, nicotinamide and NAD+ did not differ between the two ways (Wakabayashi 2026). A capsule is the simpler habit; a powder lets you set the amount by the scoop.

The timing. The 60-day trial gave one dose a day (Yi 2023). A 12-week trial in 36 healthy middle-aged adults split 250 mg into 125 mg twice a day, and serum nicotinamide, a NAD+ metabolite, rose more than on placebo (Katayoshi 2023). No trial in our evidence compared times of day, so a time you can keep each day is the practical choice.

The weeks. Blood NAD+ rose within weeks: in a 14-day trial of 65 healthy adults, NMN and nicotinamide riboside (NR) comparably raised circulatory NAD+, while nicotinamide did not (Christen 2026), and in the 60-day trial NAD+ was already up at day 30 (Yi 2023). The trials that measured walking, aerobic capacity or sleep ran 6 to 12 weeks, so that is the window the evidence covers.

What the trials measured beyond NAD+

In the 60-day trial of 80 middle-aged adults, six-minute walking distance rose more on 300 to 900 mg of NMN than on placebo, self-rated health on the SF-36 survey was better in the NMN groups by day 60, and blood biological age held steady while it rose on placebo (Yi 2023). A follow-up analysis of that trial found that bigger NAD+ rises went with longer walks and better SF-36 scores (Kuerec 2024).

In a 12-week trial of 60 older adults on 250 mg a day, 4-meter walking time was shorter and sleep quality better than on placebo, though the main stepping test did not differ (Morifuji 2024).

In a 6-week trial of 48 amateur runners training 5 to 6 times a week, 600 and 1,200 mg a day raised oxygen uptake and power at the two ventilatory thresholds more than placebo; VO2max and peak power did not differ (Liao 2021).

In the 2025 meta-analysis, most glucose and lipid outcomes did not differ from control (Zhang 2025).

Who the trials did not cover

The trials enrolled adults. Pregnant or breastfeeding women and people under 18 were not studied. If you take prescription medicine, check with your clinician first.

What is in the product

NMN Pure Powder holds 500 mg of NMN in one 0.5 g scoop, with no other ingredients, and a 100 g jar holds 200 servings. Renue lists it as a sublingual powder and says it supports NAD+ levels that help power your cells. Renue suggests one full scoop (500 mg) twice daily, starting with half a scoop twice daily for the first week if you are new to NMN. One scoop a day and two scoops a day both sit inside the 250 to 1,200 mg a day the trials used.

How long a 100 g jar lasts, from the label: about 400 days at 250 mg a day, about 333 days at 300 mg, 200 days at one scoop (500 mg), about 167 days at 600 mg, and 100 days at Renue’s suggested two scoops (1,000 mg).

For capsules, NMN Liposomal Capsules give 500 mg of NMN from two capsules over 45 servings, and Renue designs the liposomes for slower, more sustained release. For more in one capsule, NAD+ Complete is a four-in-one liposomal blend of NMN, NR, trigonelline and NAD+. For the NR route, NR Powder Smooth Taste Blend gives 1,000 mg of nicotinamide riboside per serving.
