If you had asked me a year ago how old I felt, I might have said something optimistic. After all, I was walking every day, eating reasonably well, even travelling for work and fun. But somewhere along the way, I lost track of my own wellbeing. It wasn’t anything dramatic, a string of long-haul flights, grief over losing my mother, the stress of buying a house after 18 years. Suddenly, tiredness settled in like fog. I felt older.
So when I came across Muhdo, a health platform combining DNA and epigenetic analysis with AI and blockchain, it caught my attention. Their promise? To offer actionable, science-backed insight into your biological self. Not the age on your passport, but your real, cellular age. Not what should work for someone like you, but what will work for you, full stop.
I spoke with James Brown, Director of Nutrigenetics of Muhdo, after getting my test results. What began as a curiosity quickly turned into something more profound. James wasn’t just handing me numbers, he was walking me through a deeply personal map of who I am, how I live, and how my body is responding.
“You’re only a year older biologically than you are chronologically,” he told me. “Given your stress levels over the last year, that’s incredible. You should probably be five to ten years older.”
It turns out that even my exhaustion had some hidden resilience behind it. Brown has worked with elite athletes, commercial pilots, and global research institutions. He’s seen how methylation patterns, the chemical markers that sit on top of our DNA and tell it what to do, can fluctuate with lifestyle, stress, even long-haul flights.
“Commercial pilots often age rapidly because of radiation exposure and stress from travel. Long-distance travel affects methylation patterns dramatically,” he explained. “So for you to come through a year of travel and personal upheaval and still be within a year of your chronological age – that’s a win.”
My test included insights into more than just age. Muhdo evaluates 18,000 genes and over 9,000 methylation markers. The real gold, though, is how it translates that complexity into clarity.
Brown suggested starting with the basics: vitamin and mineral deficiencies. “Magnesium, for example, is key to over 400 enzymatic reactions in the body. If you’re low in it, it can impact everything from stress and sleep to anxiety and cortisol levels.”
Vitamin D was another red flag. “Eighty percent of people in the UK are deficient,” he said. “And it’s not enough to have it in your bloodstream. It needs to bind with receptors to be effective, and your genes determine how well that happens.”
Muhdo offers its own supplement range, and while I’m typically sceptical of branded wellness products, Brown’s explanation was rooted in data. This wasn’t about trends. It was about repair.
The platform is evolving. Soon, users will have access to an AI version of Brown himself, a virtual coach embedded into the app, trained on years of science and user queries. “Little James,” as he jokingly called it, will help interpret complex results and guide lifestyle adjustments.
I confessed to Brown that I hadn’t looked deeply into my results after seeing my biological age. He reassured me that was normal. “People either obsess or avoid,” he said. “What matters is acting on it when you’re ready.”
Since taking the test, I’ve started painting again, a neglected joy that reawakens something calm in me. I’ve resumed walking daily. I’m also thinking more carefully about what I eat, what supplements I might need, and how to reduce the unrelenting churn of stress that creeps into modern life.
As Brown put it, “You can’t stop aging. But you can age better.”
He told me stories of others: high-powered couples with advanced cancer diagnoses who used lifestyle interventions to extend their lives; COVID-era clients whose biological ages jumped dramatically in just six months from stress. I felt lucky, and also reminded of how fragile that luck can be.
Muhdo isn’t promising immortality. It’s promising insight. It’s offering a way to listen more carefully to your body’s signals, and act before things go sideways.
The next phase for me is the follow-up. Brown will soon analyse my full DNA and epigenetic profile and provide targeted recommendations. I’m not expecting a miracle. But I am expecting more clarity, and maybe a nudge toward living a bit more in tune with myself.
Epilogue: The Map Forward – James provided an analysis of my results
Reading through my detailed results, I was struck by something unexpected: not fear or overwhelm, but a sense of quiet motivation. My biological age was on track. My eyes, hearing, and memory — all performing well. Even the inflammation markers that flared slightly were met with an equally strong anti-inflammatory response, as though my body was still fighting the good fight despite everything.
But knowledge is only powerful when it leads to action.
Armed with new awareness around B vitamins, selenium, and Omega 3, I now understand why energy dips or brain fog might hit harder than expected — and how to correct course. A protein-rich foundation, mindful of saturated fats and carbs, seems a sensible shift rather than a seismic one.
This isn’t about radical reinvention. It’s about refinement. It’s about listening a little more closely, adjusting a little more wisely, and ageing — not fearfully — but intentionally.
After all, as Brown said, “Most people we test come in at least three years older than their real age. You? You’re right on track. That means you’ve got the raw materials. Now it’s just about using them.”
And I will.
