Why I built a supplement you can measure
Fourteen years advising other people’s products taught me what the industry is willing to leave unproven. MUTO is what I wanted to exist instead.
PhD Molecular Biologist · Functional Medicine Nutritionist
I spent fourteen years as a consultant to supplement and health companies. I read the formulations, checked the claims against the research, and told brands what their product could honestly say. A lot of the time the answer was: less than you want to.
That work is where MUTO came from. Not from spotting a gap in the market - from being asked, repeatedly, to sign off on things I would not take myself.
The standard in this industry is lower than people assume.
Supplements are regulated as food, not medicine. That means a product can be legally sold without anyone ever demonstrating that it does what the packaging implies. The bar is safety and accurate labelling - not efficacy.
In practice that produces three habits I saw again and again: doses well below the ones used in the research being cited, cheap compound forms chosen for margin rather than absorption, and proprietary blends used to make both of those unverifiable. None of it is illegal. All of it means the customer is asked to take the claim on faith.
Citing a study, then including a fraction of the dose it used.
Compounds picked for cost, not for how much of them you absorb.
A legal way to list ingredients without saying how much of each.
Most of the market sells the surface. The work happens underneath it.
My background is molecular biology, so I look at the layer beneath the outcome. Skin, energy, recovery, sleep quality - none of those are systems. They are results, produced by cells that need to make enough energy and repair enough damage to keep producing them.
A product aimed at the surface is aimed at the readout. It can improve how something looks or feels in the short term without touching what generates it. That is why so many stacks produce a strong first fortnight and then nothing: they were never working on the machinery, and the machinery is what declines with age.
The result you can see
Skin, energy, recovery, how the morning feels. Worth caring about, but downstream of everything.
The system producing it
Mitochondria making energy and repair enzymes clearing damage - both funded by NAD⁺, which halves by your forties.
The work you see starts with the work you don’t.
Something you can track, not just trust.
The thing that bothered me most about the category is that nobody can tell whether their supplements are working. You take them, you feel roughly the same, and you keep taking them because stopping feels like a risk. That is trust doing a job that evidence should be doing.
So the brief for MUTO was different: work on something measurable, in an area where people are already collecting data. Most of our customers wear a device that records HRV, resting heart rate and sleep every night. That is a personal dataset with months of baseline in it, and it is the honest way to judge a product like this.
Which is also why the guarantee runs to ninety days. It takes that long for a trend to mean anything, and I would rather you judged us on your own numbers than on how well I write.
Every dose printed
At the level used in the research it comes from, so you can check the formula against the studies and against whatever else is in your cupboard.
Forms chosen for absorption
Active folate and B12 rather than the cheap equivalents, plus BioPerine® so the rest of the formula is absorbed rather than passed through.
Reviewed by people who can say no
A six-person scientific advisory board, all named with checkable credentials, who reviewed the formulation before manufacture.
Judged on your data
Ninety days, and a refund if your numbers haven’t moved. The measurable version of a claim is the only version worth making.
Thousands of people across the UK take it daily.
Most of them found MUTO because the last thing they tried did nothing they could point to. What comes back most often is not a feeling - it is a screenshot of a trend line.
Self-reported survey of 87 customers over 12 weeks.¹ Individual results may vary.
Three jobs, no overlap, every dose printed.
The fuel your cells need
Raw material to make NAD⁺, plus the essentials to turn it into energy.
Keeping your NAD⁺ working
The body breaks NAD⁺ down as fast as it makes it. Protecting it matters as much as producing it.
Turning it into energy you feel
The final step: making sure that energy actually gets used.
Feel it before you see it.
Then check it against your data.

There are no stimulants in the formula, so there is nothing to come down from. What people describe is a flatter line - the afternoon dip going first, usually in weeks three to four.

Recover between sessions
Hard days cost less

The day after a hard session is where it shows. Repair is an energy-funded process, and funding it better means arriving at the next session with more of the last one absorbed.

Steadier mornings

Waking up is metabolically demanding. Most people notice mornings sharpening before anything appears on a wearable.

Whatever your device calls it, it is a composite of HRV, resting heart rate and sleep. The useful signal is the weekly average lifting across a training block.

Slower to move than HRV and harder to confound. A downward drift across a month is the cleaner of the two reads.

Time asleep is an input you already control. What changes is what the body manages to do with it - the deep, restorative portion.

I did not want to be the only person who had checked it.
Six named specialists reviewed the formulation before manufacture, with the authority to reject it. It is made in a UK facility to GMP ISO standard and tested by an independent lab for purity and potency.

£29 for your first month, then £55
A low-commitment way to try MUTO and see what your own data does. Up to 58% off versus the one-time price, and you can cancel at any point.
90 days, or your money back
Ninety days is long enough for your own numbers to say something, which is why it is the window we stand behind. Log your 30-day HRV and resting heart rate average before your first capsule so the comparison is honest.
If the data hasn’t moved by day 90, tell us and we refund you. No return of the empty pouches, no argument about how you felt.
The questions I get asked most.
Why NAD⁺ rather than any of the other longevity ingredients?
Because it is upstream of most of them. NAD⁺ is the coenzyme mitochondria use to make energy and repair enzymes need to clear damage, and it declines steadily with age - by your forties you are running on roughly half what you had in your twenties. Raising the input funds both systems rather than pushing on one output.
You consult for supplement companies. Isn’t this a conflict?
It is the reason the product exists. Fourteen years of reading other people’s formulations is what showed me where the standard sits and what the category is willing to leave unproven. MUTO is the version I could sign off on, which is a different thing from the version that maximises margin.
What will I feel, and what will I see on my wearable?
There are no stimulants in it, so nothing in the first hour. Most people describe the afternoon dip going first, in weeks three to four, then steadier mornings. On the device it is slower: HRV and resting heart rate typically start moving between day 30 and day 60, read as a weekly trend rather than a single morning.
I already take a stack. Does this replace any of it?
Often two or three products. Every dose is printed in full, so overlap is visible rather than guessed at - most people find the B vitamins, zinc and CoQ10 they were buying separately are already covered here at research-level doses.
What if my data doesn’t move?
Then send it back. The 90-day guarantee exists because I would rather you judged this on your own numbers than on how the marketing reads. Log your 30-day HRV and resting heart rate average before you start so the comparison means something.

I didn't build MUTO because I saw an opportunity.
I built it because I couldn't find a product I'd take myself.
This category runs on single ingredients, proprietary blends and claims nobody has to answer for. MUTO is the opposite of that: fifteen ingredients, every dose printed, every batch third-party tested, and independent university trials I don't control the outcome of. My name is on the label because I'm accountable for what's behind it.
No proprietary blends. Fifteen ingredients, fifteen doses, on the label. If I won't show you the number, I shouldn't be selling you the capsule.
Coventry and Newcastle are running independent trials on MUTO. I don't control the result. That's the entire point of asking.
Filler-free, UK GMP, third-party tested. Every batch checked before it reaches you - not after someone complains.
Take it for 90 days. If it hasn't earned its place, you get your money back. I'd rather refund you than have you talk yourself into it.

Your 90-day MUTO journey
MUTO starts working from day one - beneath the surface, before your wearable has anything to show. This is the input building.
Steadier energy. Fewer crashes. A calmer baseline to train from. The system's compounding - you'll feel it first.
HRV is the honest number - your nervous system reporting on your cells. This is where the system beneath starts to show.
By day 90, it's not just felt - it's on the screen. The standard you hold above starts to show in the system beneath.
What your wearable measures - and what it doesn't
What your wearable measures - and what it doesn't
HRV. Recovery. Readiness. Sleep quality. Every one of those scores is your cells doing energy work well or badly, converted into a number. MUTO supports how the billions of cells in your body produce that energy - the input behind the output.

How it fits your stack - and when it doesn't
How it fits your stack - and when it doesn't
- Most NAD⁺ supplements give you a precursor and stop there. But making NAD⁺ is only the first of three jobs - skip the other two and you're paying to produce NAD⁺ your body loses or never turns into energy you feel.
- Produce - NR gives your cells the building block they turn into NAD⁺. Essential, but on its own it's one third of the job. It's where NMN and NR stop - and where MUTO starts.
- Protect - An enzyme (CD38) breaks NAD⁺ down almost as fast as you make it. Quercetin, Pterostilbene, Grapeseed and Turmeric slow that leak, so the NAD⁺ you produce actually sticks around.
- Put to Work - NAD⁺ in your blood isn't energy yet. CoQ10 and BioPerine® help your cells absorb it and turn it into energy you feel - not just a better number on a lab report.
- Produce without Protect is a leaking tank. Produce without Put to Work is fuel you never burn. NR and NMN do one job. MUTO does all three.
