FIRST BOTTLE FREE · 60-DAY MONEY-BACK GUARANTEE

Your energy fades after 40. So does your NAD+.

NAD+ rose about 60% in a precursor trial.

NAD+ is the molecule your cells use to turn food into energy, and brain scans show the levels fall with age.

How to take it

Take two capsules a day. Keep the bottle closed and somewhere cool and dry.

Why NAD+ matters

NAD+ falls as you age, and your cells need it to make energy.

Every cell uses NAD+ to turn food into energy and to repair DNA, and in brain scans of healthy adults the levels fell as age went up. Most of the research has used NMN or NR, precursors your body has to convert into NAD+. This capsule holds NAD+ itself, so there is no conversion step.

The trial

In a placebo-controlled trial, an NAD+ precursor raised NAD+ in blood cells by about 60%.

Researchers at the University of Colorado Boulder gave healthy adults 1,000 mg a day of nicotinamide riboside, a precursor your body turns into NAD+, for 6 weeks.

Why the first bottle is free

You’ve already tried supplements for energy that did nothing.

So your first bottle is free. It lasts 30 days, long enough for blood NAD+ to rise in the trials, and we think you’ll want the next one.

THE STUDY

In a 65-person trial, 14 days of NR or NMN roughly doubled NAD+ in the blood, while plain nicotinamide did not.

ORAL NAD+

In a 2026 trial of 60 adults, 5 days of an oral NAD+ product raised NAD inside their blood cells by 53% compared with a placebo.

THE DOSE

In 80 healthy middle-aged adults, 60 days of NMN raised blood NAD at every dose from 300 to 900 mg a day, and the people on NMN walked farther in six minutes than the people on a placebo.

ENDURANCE

A pooled analysis of 27 studies found that NMN improved endurance in a dose-related way.

What is in
each capsule.

Most capsules also contain magnesium stearate or silica, which help the powder run through the machines. Ours is just NAD+ and the vegan capsule.

500 mg

NAD+

The full name is β-nicotinamide adenine dinucleotide. Each capsule holds 250 mg.

Everything else

No fillers, stearates, silica or flow agents.

You take two capsules a day.

What NAD+ is used for

Brain

Brain scans of healthy adults show less NAD+ in older people.

Energy

Cells use NAD+ to turn food into energy.

Focus

Your brain uses about a fifth of your body’s energy, and NAD+ helps make that energy.

Cell health

Enzymes use NAD+ to repair DNA.

How NAD+ works in your cells

NAD+ is found in every cell. Enzymes use it to release energy from food and to repair DNA.

NMN and NRYour body converts them
Our capsuleNAD+ itself
Read the science

Your body makes NMN and NR into NAD+. Our capsule skips that step and contains NAD+ itself.

Taking it every day

  1. Start with one bottle

    Your first bottle has 60 capsules, enough for 30 days.

  2. Keep it where you’ll see it

    Put it next to something you use every morning, so you remember to take both capsules.

  3. Take it every day

    The trials ran from two weeks to twelve, so give the first bottle all 30 days before you decide.

Has NAD+ itself been studied in people?

One 2026 placebo-controlled trial of an oral NAD+ product raised NAD inside blood cells by 53% in 5 days. Its formula was not ours, and most of the research so far has used the precursors NMN and NR.

What else is in the capsule?

Only the vegan capsule that holds it.

Is this the same as NMN or NR?

No. NMN and NR are precursors that your body converts into NAD+. This capsule holds NAD+ itself, the coenzyme.

What should I expect, and how soon?

In the trials, blood NAD rose within two weeks, and walking distance and leg strength improved by 8 to 12 weeks, so give the first bottle all 30 days before you decide.

How do I take it?

Take two capsules a day with water. Each bottle has 60 capsules, enough for 30 days. Keep it tightly closed in a cool, dry place, and out of reach of children.

How does the monthly subscription work?

Your first bottle is free and ships free. The plan includes your first refill, which ships on day 30 for $59.99, and after that a bottle ships every month at the same price. If you’d rather buy once, a single bottle is $69.99 plus shipping.

Why is the first bottle free?

The trials ran from two weeks to twelve, and we want you to give it the full 30 days. If it isn’t right for you, you have 60 days to get your money back, even if you’ve opened the bottle.

What if it isn’t right for me?

You have 60 days to get your money back, even if you’ve opened the bottle, and returns are free. Email or call us and we’ll help you send it back. Read the full return policy.
