Multi-omics & holo-omics
In plain language
Imagine your health as a symphony. Your DNA writes the notes, your metabolites play the instruments, and your microbiome forms the orchestra. Only when everything sounds together do you hear the full melody. Single tests give just one instrument: a DNA test shows predisposition, but not how your body behaves today; a blood test shows metabolites, but not the source of the imbalance; a microbiome test shows bacteria, but not why your reaction is unique. Only the combination gives a reliable picture — the difference between a photo and a film. Multi-omics reveals the dynamics of your health, and holo-omics places that film in its ecosystem: you and your microbiome as a single inseparable whole. In this way understanding shifts from separate puzzle pieces to the whole story.
The science behind
Multi-omics integrates layers that each show a different time window. The genome describes predisposition (what is possible), the metabolome the current state (what is happening now) and the microbiome the living community that helps determine nutrition and signals. Research in Nature Biotechnology confirms that bringing these layers together makes visible early signals that remain hidden in a single layer — a shift towards precision and prevention.
Holo-omics adds the holobiont perspective: human and micro-organisms are viewed not separately, but as a single ecosystem. The Lancet Digital Health describes this as a necessary evolution in precision medicine, because connections between nutrition, gut flora, genes and lifestyle only become visible at this level. Examples make it concrete: a gene variant can show that you break down lactose less well, while the microbiome shows whether beneficial bacteria partly compensate for that; in recovery after exercise, a richer microbiome (more SCFA production) helps explain why one person recuperates faster than another.
The connecting logic is co-metabolism: no single layer tells the story on its own. It is precisely by reading DNA, metabolites, microbiome and lifestyle together that a picture emerges robust enough to base personal choices on, including around ageing and longevity. This reading is supportive and observational — not a medical diagnosis.

Frequently asked questions
- What is the difference between multi-omics and holo-omics?
- Multi-omics analyses several layers (DNA, metabolome, microbiome) together; holo-omics adds that the human and the microbiome form a single ecosystem: the holobiont.
- Why is one test not enough?
- Each single test shows one layer and one moment. Only the combination reveals the dynamics — the difference between a photo and a film.
- What can I discover with multi-omics?
- For example why you react sensitively to certain foods, how quickly you recover, or which early signals point towards imbalance.
- Is multi-omics a diagnosis?
- No. It is a supportive, observational reading that gives insight and direction, not a medical diagnosis.
