Health becomes personal
We didn't have a business plan, we had questions.
What happens when your body gets out of balance?
Marcus was ten when a rare inflammatory disease forced him to deal with things that aren't really part of a child's life. David was in his early twenties when he was diagnosed with leukemia.
Two profound changes that continue to shape our founders today—and which, years later, became the beginning of a shared quest: How does health really work? How can we regain it when it seems lost? How can we strengthen it—and what does it take to maintain it in the long term?

From experience to responsibility
"The world of health products is full of big promises – but often lacking in substance. The industry had a poor reputation then, as it does now – and in many respects, rightly so. And that's exactly what we wanted to change.
Marcus Haag laid the foundation with his first company in 1998 – at the time he was just 19 years old. In 2013, he took over Cellavent, which had already been founded in 2006. Together with David Bansleben and Prof. Dr. Ingo Schellenberg – who conducted research in the field of nutritional medicine and secondary plant substances – and a dedicated team, he shaped Cellavent into one of the leading providers of natural health solutions over the next few years.
Personally motivated, scientifically sound, uncompromising in quality.

We do it differently
Specialized by Cellavent Healthcare
The focus – people. Standard solutions? Not with us. With our Specialized concept, we focus everything on people – not on the mainstream or trends.
Because no two bodies are alike. We develop products that are targeted, differentiated, and intelligently formulated – with the aim of offering individual solutions for specific preventative or therapeutic challenges.

NutriScience.LAB
Where nature meets evidence
The center of our work today is the NutriScience.LAB – our own scientific centerpiece. Here, we work with experts to answer a simple yet extremely challenging question: What really works – and why?
We think about health not from the gut, but from the head: Each of our recipes follows a comprehensible concept, each ingredient has a clear place and a proven effect. We focus not only on individual ingredients, but also on effective synergies, optimal bioavailability, and the conscious avoidance of unnecessary additives.
