OUR JOURNEY

Built for resilience. Designed to help you bounce back.

MUTO was founded by Dr Richie Barclay, a PhD in Longevity and Cellular Ageing Nutrition and a consultant nutritionist on London’s Harley Street.

After years in pharmaceutical and clinical nutrition, Richie saw a clear problem: most supplements didn’t address the root causes of declining energy, recovery and resilience. Formulas were under-dosed, quality control was inconsistent, and “longevity” was treated as a trend rather than a biological process.

So he stepped away to build something better - a UK-made nutraceutical brand grounded in cellular science, formulated at clinically relevant doses, and verified through rigorous third-party testing and clinical trials.

No fillers. No unnecessary excipients.


Just science-led formulations designed to support cellular health at its foundation.

WE ARE COMMITTED TO CREATING THE HIGHEST QUALITY PRODUCTS

Quality begins long before the capsule.

Every stage of our production is guided by pharmaceutical-grade standards and rigorous testing:

formulation

Our formulas are excipient- and filler-free, built on insights from 300+ human clinical studies and dosed at levels shown to be effective. Each ingredient is selected to work synergistically across six key cellular pathways, supporting energy, repair, and long-term cellular health - not just in isolation, but as an integrated system.

formulation

BIO-AVAILABILITY

What matters is what your body can actually use. Our formulas prioritise bioavailable ingredient forms - choosing pterostilbene over resveratrol, methylated B vitamins, and clinically validated delivery to support real cellular uptake.



This approach is informed by human research showing oral NR can significantly increase NAD⁺ levels by 51% within two weeks, reinforcing our focus on effectiveness, not just ingredients on a label.

BIO-AVAILABILITY

Ingredient verification

Every ingredient is rigorously verified for identity, purity, and potency before it enters our supply chain. We work only with trusted UK-based partners and fully traceable sources to ensure consistency, quality, and safety from the very first step.

Ingredient verification

UK production

All MUTO products are manufactured in the UK to pharmaceutical-grade standards, with strict quality controls in place at every stage. This ensures precision, batch-to-batch consistency, and uncompromising quality you can trust.

UK production

Third-party testing

Each batch is independently tested to confirm ingredient accuracy, dosage, and freedom from contaminants. This extra layer of verification ensures what’s on the label is exactly what you take - every time.

Third-party testing

clinical trials

Our formulas are informed by 300+ human clinical trials and supported by our own investment in randomised clinical trials with UK- and Australia-based institutions. This level of clinical commitment is rare in the supplement industry - and it’s a standard we choose to set and uphold.
