Most tests measure separate parts. My InnerSelfie reads how your DNA, your gut and your lifestyle work together (we call this co-metabolism) and translates that into one clear plan. With HostHero, your personal health guide, day and night.
Your first analysis gives you your full picture, yours, forever. From then on you simply follow up — with your free wearable connection, unlimited. A retest is always possible, whenever it makes sense for you.
Or pay with Klarna — now or spread out, depending on what Klarna offers in your country.
The new My InnerSelfie app is ready in the App Store and on Google Play. Read your reports, discover your BioHacks and connect your watch or ring, now free of charge.

This is what your at-home test looks like: everything is in the kit, with clear instructions.
Take the analysis, or bring your own data. We read your body: DNA, gut and lifestyle.
You see in color where you are in balance and where you are not: clear, without jargon.
You get your steps and your personal monthly package. With Connect you stay supported.
You try to eat healthier. You buy supplements. You sleep more. And yet you feel that something is missing. Tired for no reason. Bloated after eating. Brain fog that just won't lift. Or skin problems, joint pain, mood swings, slow recovery: complaints that are often connected through the gut–organ axes. And at the doctor's: “everything looks normal.” Normal? That's not how it feels. You're not imagining it. Your body is trying to tell you something.

The same food, the same supplements, the same advice, and a different result for you. That's because health doesn't come down to a single number. It lies in your co-metabolism: the way your genes, your micro-organisms and your lifestyle interact. That co-metabolism is unique to everyone. Including you.
We've been thinking about this subject for more than twenty years, and brought that science together in the COSMO books, HOST and FORMULA.
Where others give one snapshot, My InnerSelfie brings three pictures together into one clear story. The way everything works together is what we call co-metabolism:
The micro-organisms that help determine how you digest, recover and feel.
What you were born with — your sensitivities and your strengths.
How your body actually responds today, in your life.
For twenty years we saw the same thing: people were told “everything looks normal”, while they didn't feel normal at all. That's why we built My InnerSelfie. Not to collect even more numbers, but to make visible how everything works together in you, and what you can do about it.
Not a cold app full of numbers, but a guide that thinks along with you. HostHero translates the science into plain language and answers your questions, day and night, as your personal health guide.
Behind the scenes, OSCAR translates more than 740,000 biological data points into understandable insights. AI helps, but never decides alone. You and your guide stay in control.
From nutrition and gut to sport, recovery, stress, hormones and skin — choose what matters to you, or view the whole picture. In everyday language; the scientific name is shown small underneath.

Professionals, medical experts and top athletes who work with My InnerSelfie — in their own words.
“For many patients with chronic complaints, fatigue and impaired function, combined analyses of the genome, metabolome and microbiome can be extremely valuable. Thanks to the insights gained, we can offer these patients a meaningful, high-quality life again through personalized advice on nutrition and well-being.”
Prof. Dr. Luc Vanden Bossche
Head of Physical Medicine and Rehabilitation, Ghent University Hospital
“Since I started using Cosmogroup's personalized approach to supplementation and sports nutrition, I've been able to recover faster from intense efforts, and my gut complaints during training and competition have disappeared completely.”
Koen Naert
European marathon champion (2018)
“I'd been struggling with gut complaints for a while and was constantly tired and had muscle cramps. After a multi-omics test it turned out my gut flora was disrupted. Thanks to Cosmogroup's personalized supplements my gut complaints have disappeared and I feel 100% fit again, so I can train at full intensity once more.”
Delfine Persoon
Boxing, world champion across all federations

Dr. Patrick Tonnard

Bart Verhaeghe
Entrepreneur and chairman of Club Brugge
“As a professional cyclist I ate sports nutrition that was too one-sided, which caused a dysbiosis in my gut flora, brought back into balance almost immediately thanks to a personalized approach. Above all, I felt fitter to take on training and competition.”
Ben Hermans
Professional cyclist, Team Cofidis
“I had been dealing with a sensitive stomach for years, which impacted both my workouts and daily routine. After the in-depth analysis and personalized supplements from My InnerSelfie, I noticed a remarkable improvement in my energy, recovery and overall performance. I wish I had taken this step much earlier.”
Thor Bendix Madsen
Professional Danish Triathlete
“As an orthopedic surgeon and team doctor, I strive for the highest standard of care. I carefully integrate conditioning training and personalized supplements — this not only boosts my own performance but underlines my commitment to patient care.”
