Resveratrol and NMN: Taking Them Together

Quick answer

NMN and resveratrol are paired because of laboratory research: resveratrol was developed as an activator of sirtuins, enzymes that need NAD+, and NMN raises NAD+ in the blood. We found no trial in people that tested them together. Europe judged NMN safe up to 300 mg a day and caps resveratrol supplements at 150 mg.^1,2,3,4

Key facts

A meta-analysis of 12 trials found that NMN raised blood NAD+, while most of the health measures checked did not differ from placebo.²
At least 70% of a resveratrol dose is absorbed, but only traces reach the blood unchanged.⁵
Our NMN gives 500 mg a day and our Resveratrol label 600 mg of trans-resveratrol a day, both above Europe's figures.^3,4
Four weeks after the last dose of NMN, blood NAD+ was back at its starting level.⁶

Why they are sold as a pair

The pairing comes from laboratory and animal research on aging. Sirtuins are enzymes that need NAD+ to work. Resveratrol was developed as an activator of one of them, SIRT1, and NMN feeds the body's supply of NAD+, so the idea is that one supplies the fuel while the other flips the switch.¹

That idea has not been tested in people. We found no trial that gave both, and the evidence for each one alone is thin: NMN reliably raises a blood marker, and resveratrol's one graded finding is small and from mixed groups of people.^2,7

At least 70% of a 25 mg dose was absorbed, yet only trace amounts of unchanged resveratrol reached the blood; its sulfate and glucuronide forms reached levels up to about 20 times higher.^5,8

What each has shown on its own

Neither finding below involves the other ingredient, and neither measures aging itself.

Raises NAD+ levels in the blood*^2,3,9

Moderate evidence

A meta-analysis of 12 randomized trials (513 adults) found that NMN raised blood NAD+, and a 60-day trial in 80 healthy adults aged 40 to 65 found increases at 300, 600 and 900 mg a day. The trials were small and short, several were funded by NMN makers, all carried some risk of bias, and the same meta-analysis found that most health outcomes were no different from placebo.

Amount studied: 250 to 900 mg a day, for up to 12 weeks

May support normal blood vessel function*^7,10

Early evidence

A 2022 meta-analysis of randomized trials found a small improvement in flow-mediated dilation, a test of how well an artery widens (about 1.4 percentage points); a 2026 umbrella review rated this as moderate-certainty evidence from 8 trials (603 people) that used 30 to 500 mg a day for 1 to 24 weeks. The trials enrolled mixed groups that included people under medical care, none used this product's 600 mg label dose, and the umbrella review saw weaker or less favorable results overall at 500 mg a day or more.

Amount studied: 30 to 500 mg a day for 1 to 24 weeks

Across 12 randomized trials, most of the health measures checked, including blood fats, did not differ from placebo.²

Exercise: single trials that point different ways

In 27 inactive men around 65 doing 8 weeks of high-intensity training, the gain in maximal oxygen uptake was 45% larger with placebo than with 250 mg of trans-resveratrol a day.¹¹

In 48 amateur runners training for six weeks, breathing-threshold measures changed more than with placebo at 600 and 1,200 mg a day, while maximal oxygen uptake and peak power did not change.¹²

These are single trials in different groups, older inactive men and young amateur runners, so they do not show that one ingredient cancels the other. They do show that the two have not behaved alike when taken with training.^11,12

When to take them

No study tested a schedule for the pair. The separate studies did this:

Trials have given NMN once a day before breakfast with water, or split into a morning and an evening dose.^6,9

In a 12-week trial of 108 adults in their 70s, 250 mg was taken either before noon or between 6 pm and bedtime. Chair-stand times and drowsiness scores changed most in the evening NMN group, but the evening placebo group's drowsiness scores also changed, and the NMN maker funded the trial.¹³

Resveratrol reaches its highest level in the blood about 30 minutes to 2 hours after a dose.^14,15

At 2,000 mg twice a day, a high-fat breakfast lowered blood levels by about 45% compared with a standard breakfast.¹⁶

So the trials do not settle a best time. NMN has been taken before breakfast and in the evening, and with resveratrol, the timing question the studies answer is about meals rather than the clock.^6,13,15

How much of each

Amounts for adults, ingredient by ingredient^3,4,7,8,17
	NMN	Resveratrol
Most common amount in trials	250 mg a day	30 to 500 mg a day in the blood vessel trials
Range tested	250 to 2,000 mg a day, for up to 24 weeks	Up to 5 g a day for 29 days in healthy volunteers
Europe's figure	Judged safe up to 300 mg a day	Capped at 150 mg a day of synthetic trans-resveratrol
Our product, per day	500 mg	600 mg of trans-resveratrol at two capsules

No source sets an amount of resveratrol to go with NMN; the figures above are each ingredient's own. In the blood vessel trials, results were weaker at 500 mg of resveratrol a day or more, so a larger amount did not do better there.⁷

What's in ours

What’s in ours

NMN: β-Nicotinamide Mononucleotide, 500 mg per serving, from the label

Both of our labels sit above Europe's figures: 500 mg of NMN against the 300 mg Europe assessed, and 600 mg of trans-resveratrol a day at two capsules against the 150 mg cap. One resveratrol capsule, 300 mg, is closer to the amounts studied.^3,4,7

Side effects, medicines and who should ask first

Use for longer than 24 weeks has not been studied in trials, so long-term effects are unknown.^3,17

Europe counts NMN as a source of nicotinamide, so it adds to the vitamin B3 in multivitamins and in niacin, nicotinamide or nicotinamide riboside supplements.³

In 11 healthy adults taking 250 mg each morning for 12 weeks, insulin measured after lunch rose, by very different amounts from person to person.¹⁸

In a 2026 review, trials lasting 12 weeks or more raised alkaline phosphatase, an enzyme measured in routine blood tests, an effect rated high certainty.⁷

Ask your pharmacist or doctor first

NIH's LiverTox database lists a possible interaction between resveratrol and anticoagulant blood thinners. The warfarin label asks for more frequent INR checks whenever a botanical product is started or stopped, and MedlinePlus says some supplements may raise the risk of bleeding with warfarin.^19,20,21

Expected from how the two work, not shown in studies

Nobody has measured what the two do together to blood tests or to medicines. Each has been studied for 24 weeks at most, so for the pair, long-term effects are a blank.^7,17

Ask your doctor or pharmacist first if you take any prescription medicine, including medicines for blood sugar^4,18
Ask first if you take a blood thinner or have a bleeding disorder¹⁹
Ask first if you already take niacin, nicotinamide or nicotinamide riboside³
Ask first if you take estrogen, have a hormone-sensitive condition or have liver disease¹⁹
Ask first if you are pregnant or nursing, or under 18: Europe's NMN assessment does not cover pregnancy or breastfeeding³

Questions people ask

Does resveratrol need to be taken with fat?

The studies we read do not back that up. After a high-fat meal, a 400 mg dose peaked later but the total absorbed did not change in a relevant way, and at 2,000 mg twice a day a high-fat breakfast cut blood levels by about 45%.^15,16

How much resveratrol per day should go with NMN?

No source sets an amount for the pair. On its own, resveratrol's blood vessel trials used 30 to 500 mg a day, and the EU caps synthetic trans-resveratrol in supplements at 150 mg a day.^4,7

What is the best time to take NMN and resveratrol?

No trial compared times for the pair. NMN trials gave it before breakfast or split it between morning and evening, and in one study more resveratrol reached the blood after morning doses than after later ones.^6,9,14
