Cellular longevity · 500 mg NMN at 99.9% purity, one capsule a day
NAD+ falls with every decade. NMN is the most direct way to help your body make more.
NAD+ is the coenzyme every cell spends on energy and repair, and it falls steadily with age. NMN is the molecule your body converts into NAD+ in a single enzymatic step, which is why it's the precursor the longevity field keeps coming back to. One capsule, 500 mg, nothing else in it. The simplest daily habit in the category.
- More of what repair runs on: supports your body's own NAD+ production, one step from the finished molecule
- Steady, not stimulated: supports normal cellular energy metabolism, the quiet kind, not the caffeine kind
- The long game: supports the processes involved in healthy aging at the cellular level
- Checkable in ten seconds: 500 mg of NMN at 99.9% purity, the whole label
- Backed for 60 days: finish the bottle and still get refunded if it didn't earn its place
Step one: the problem
Nobody feels themselves age. They notice that they have.
It doesn't arrive on a particular morning. It's the workout that takes two days to shake off instead of one. It's the afternoon that used to be productive and now needs a second coffee. It's the photograph that looks slightly further along than the face you carry in your head.
None of it announces itself. It accumulates quietly for years before it's obvious.
Here is what it costs if nothing changes: the pool your cells run on keeps falling, a little every year, whether or not you're paying attention. Maintenance that doesn't get resourced doesn't get done. It gets deferred, and deferred maintenance is what aging fast looks like from the inside.
Which is exactly why it's worth understanding what drives it, instead of waiting for the mirror to bring it up.
The root cause
Your cells didn't stop working. They ran short of the one thing repair runs on.
Every cell you own does its energy production and its maintenance work on a coenzyme called NAD+. Mitochondria burn it to make energy. Sirtuins spend it to switch on DNA repair. PARP enzymes consume it when damage needs fixing. No NAD+, no repair: the machinery is still there, but it has nothing to run on.
NAD+ falls as you age, and by midlife most people carry markedly less than they did in their twenties. So the practical question becomes: what is the shortest route to helping the body make more of it?
That is the whole reason NMN exists as a supplement. Nicotinamide mononucleotide is the molecule one enzymatic step before NAD+. Give the body NMN, and the last step is the only one left.
The solution
One molecule. One step. One capsule.
NMN does one thing, and the label reflects it. Here is what that one thing supports.
The mitochondria
NAD+ is what mitochondria use to turn food into usable energy. Supporting the pool supports normal cellular energy metabolism, the quiet kind, not the caffeine kind.
The sirtuins
Sirtuins are the enzymes that run DNA maintenance and cellular housekeeping, and they are NAD+-dependent. They only work when there is a pool to spend.
The long game
Supporting NAD+ supports the processes involved in healthy aging at the cellular level. It is maintenance, done daily, for the timescale maintenance runs on.

Why other approaches fall short
Why the cheaper routes to NAD+ do less than they claim
Every approach below is aiming at the same pool. The difference is how many steps away it starts, and whether you can read the dose.
| The usual move | Where it falls short | NMN |
|---|---|---|
| Niacin (vitamin B3) | Three enzymatic steps from NAD+, and the flush at useful doses is famous for a reason. | One step away, no flush |
| Nicotinamide riboside | A precursor to the precursor: your body converts it to NMN first, then to NAD+. | Already NMN, so that conversion is skipped |
| Low-dose NMN gummies | A small dose in a sugar base that sounds like NMN and delivers a fraction of it. | 500 mg in a capsule, no sugar |
| Longevity blends | A long list of ingredients at undisclosed doses, with NMN somewhere inside. | One ingredient, one number, printed on the front |
| Stimulant energy formulas | You feel the caffeine, not the cell. And you can't tell the two apart. | Nothing you feel in twenty minutes |
Why this works
The simplicity is the point
It starts one step from the finish line
Every other precursor asks your body to do more work first. NMN is the last intermediate before NAD+, which is why it's one of the precursors the longevity field has studied most.
The dose is checkable
500 mg at 99.9% purity is printed on the label. You can compare it against anything on the shelf in ten seconds, which is a deliberately uncomfortable standard for us to hold ourselves to.
It's the easiest habit to keep
One capsule, once a day, with anything. No loading protocol, no cycling, no stack to remember. The habit that survives a bad week is the one that works over years.
Before and after
What changes, and when
The honest before-and-after here is cellular, not cosmetic. We don't have customer transformation photos and we're not going to manufacture them.
The declining pool
- NAD+ falling year on year
- Mitochondria short of what they burn for energy
- Sirtuins short of what they spend on repair
- Maintenance work quietly deferred
The supported pool
- 500 mg of the direct precursor, daily
- Normal cellular energy metabolism supported
- Sirtuins supplied with what they run on
- Maintenance resourced, for the long game
- Days 1 to 7 Nothing dramatic The honest answer: most people feel nothing in week one. This isn't a stimulant, and anything that hits you on day one probably is.
- Weeks 2 to 3 The quiet stretch Where most people quit. Nothing visible has changed, so it feels like nothing is happening. You're a third of the way through a fair trial.
- Weeks 4 to 6 The sideways notice People tend to catch this one indirectly: a session that didn't cost as much the next day, an afternoon that didn't sag.
- Week 8 The honest test Two bottles is a fair trial. If it hasn't earned its place by day 60, that is exactly what the guarantee is for. Email us before the 60 days are up.

The goal isn't living forever. It's still being yourself at seventy.
Nobody gets to skip aging. But the gap between aging well and aging fast is mostly maintenance: whether the repair systems you already have are resourced well enough to keep up. NAD+ is what they run on, and NMN is the shortest road to helping your body make more of it. The outcome is quieter than a number: a session that doesn't cost you the next day, an afternoon that holds, and a habit so small you stop thinking about it.

How to use it
One capsule. That's the entire protocol.
- Take one capsule dailyWith a glass of water. Morning is the habit most people keep, but consistency matters far more than timing.
- With food or withoutNeither helps nor hurts enough to plan your day around it. Take it when you'll actually remember.
- Give it two bottlesOne bottle tells you very little about a daily routine; two tells you what you need to know.
- Store cool and dryAnd don't use it if the safety seal is missing or damaged.
Do not exceed the recommended dose. Not for anyone pregnant, nursing or under 18. If you're managing a medical condition or taking prescription medication, speak to your physician before starting this or any dietary supplement.
The 60-Day Empty-Bottle Guarantee
Take it every day. Finish the bottle, or both bottles if you ordered two. If, within 60 days of your first delivery, you don't think it earned its place in your routine, tell us and we refund every bottle from that order, empty bottles and all.
We'd rather carry that than have you judge something that works on a 60-day timescale by how you feel after a week.

The direct precursor, for about the price of a coffee a day

What you might be thinking
The six things people think before they order
Answered plainly, in the order people usually think them.
Because the pool doesn't wait for you to feel it. NAD+ falls a little every year from your twenties on, and the maintenance it funds gets deferred long before anything shows. The people who get the most out of a daily precursor are the ones who start while there is the most left to protect.
So have we, which is why this label is one number, 500 mg at 99.9% purity, and why the guarantee runs 60 days instead of 30. Finish the bottle, or both. If it didn't earn its place, you get every dollar of that order back, empty bottles and all.
It was unclear for nearly three years, and some retailers still repeat it. In September 2025 the FDA reversed its earlier position and no longer excludes NMN from the definition of a dietary supplement. Ours is manufactured in the USA.
They all aim at the same pool; the difference is how many steps away they start. Niacin is three steps out and flushes. NR converts to NMN first. NMN is one step from NAD+. If you want the direct precursor in the simplest possible habit, this is it. If you'd rather have NAD+ itself alongside support for what drains it, that's our NAD+ Advanced. Both are legitimate routes; you don't need both.
Probably not in week one, and that's the expected answer. Nothing here is a stimulant. Most people notice it sideways, weeks in: a session that didn't cost as much the next day, an afternoon that didn't sag. Feeling a supplement and benefiting from one are different things.
It's one ingredient at 500 mg and 99.9% purity, which is the expensive version of one ingredient. Per day it works out to about the price of a coffee, and unlike a longevity blend that hides its dose, you can check this label against anything on the shelf in ten seconds.

Questions
What people ask before they order
Is NMN legal to sell as a supplement?
Yes. From late 2022 the FDA's position was that it wasn't, and you'll still find retailers saying so. In September 2025 the FDA reversed that position and no longer excludes NMN from the definition of a dietary supplement. Ours is manufactured in the USA.
NMN or NAD+ Advanced: which one is for me?
NMN is the precursor: one molecule, one capsule, your body makes the NAD+. NAD+ Advanced is the three-part approach: NAD+ itself, plus quercetin for the enzyme that consumes it and resveratrol for the sirtuins that spend it. If you want the simplest possible daily habit, NMN. If you want the whole system addressed, NAD+ Advanced. Taking both isn't necessary.
Why not just take niacin?
You can, and it's three enzymatic steps away from NAD+ instead of one, with the flush that makes useful doses unpleasant. NMN skips the steps and the flush.
How is NMN different from NR?
NR is converted to NMN in the body first, and then to NAD+. NMN starts one step closer. Both are legitimate precursors; this is the more direct one.
When will I notice something?
Probably not in the first week, and that is the expected answer rather than a disappointing one. See the timeline above. Two bottles is a fair trial, which is why the guarantee runs 60 days rather than 30.
Is it third-party tested?
We don't currently publish a third-party certificate of analysis, and we're not going to claim one we can't show you. What we can tell you is that it's manufactured in the USA at 99.9% purity and the whole label is one number.
Does it contain caffeine or stimulants?
Neither. If you want something you feel twenty minutes after swallowing it, this isn't that product. Feeling a supplement and benefiting from one are different things.
Can I take it alongside my other supplements?
Usually, yes, but we're in no position to know what else you take. Ask your physician, particularly if you're on prescription medication.
Who shouldn't take this?
Anyone under 18, anyone pregnant or nursing, and anyone managing a medical condition without speaking to their physician first.

P.S. Your NAD+ is lower today than it was a year ago, and that carries on whether or not you do anything about it. One capsule a day is the smallest possible way to start, the whole label is one number, and the first 60 days are covered by the guarantee: finish the bottle and still get refunded if it didn't earn its place.
