The vision

A world where
biological age is
a choice,

and peak
performance has no
expiry date.

The mission

Biology sets
limits, we intend
to move them.

Every dose on the label. Every claim substantiated. A way to see the difference in your own data. And university research that puts our formula under scrutiny, results and all.

Energy

Energy you make, not energy you borrow.

Stress

Support for the system that absorbs the load, so a hard week costs you less.

Recovery

Recovery is cellular work, not just rest. This is the input behind the score.

Healthy ageing

The long game, measured in decades rather than weeks.

Most supplements
ask for your trust.

We'd rather
you check.

Nothing Hidden

Every dose and form on the label, and why it's there. Check it before you buy.
Baseline

Before your first dose, note your seven-day wearable averages, or a 30-second check-in on how you feel.
Track the Trend

HRV, resting heart rate, recovery, sleep and how you feel. 30-day averages, not single nights.
Check in Date

You choose it. Look at the trend at weeks 4 and 8, and judge it over 60 to 90 days.
Your Call

If your numbers haven't moved and you don't feel the difference, the 90-day guarantee covers you.

Meet our
founder.

Dr Richie Barclay, Ph.D.

I built MUTO because I was tired of a category that asks you to take it on trust: single ingredients, proprietary blends, and very little accountability.

I'm a scientist, so I built the opposite. A 19-ingredient cellular complex with every ingredient and every dose on the label, and the reason each one is there.

Then I wanted it tested properly. We're running research programmes with the University of Westminster, King's College London, Coventry and Newcastle, and we'll publish what we find, whatever it shows.

And you don't have to take my word for any of it. Take your baseline, track the difference, and make your own call.

I track all my data with a Whoop band. In the first 4 weeks: my HRV went up by 32%, my resting heart rate dropped by 7%, and my average recovery score improved by 26%. Considering I've already got training, nutrition and sleep dialled in, that's pretty wild.
