Our mission: Rethinking health

Leon Benedens, Paul Seelhorst, and Christian Goldau founded Viktilabs in 2020 after experiencing negative experiences with chronic diseases and health conditions. Paul Seelhorst, in particular, knows his own ordeal firsthand: After years of suffering from autoimmune symptoms, allergies, and mental health issues, he regained his health through targeted dietary and lifestyle changes. These personal experiences motivated the founders to take their health into their own hands and create a brand that stands for purity, efficacy, and transparency.

Viktilabs was born out of a personal desire to specifically close supply gaps and meet the increased demand for vitamins and vital substances with natural, laboratory-tested products. The founders focus on uncompromising quality, sustainability, and a close-knit community.

To date, Viktilabs has remained completely self-financed and independent of external investors.

Their mission: to help people find their individual balance of vitality and well-being – with nutritional supplements they can truly trust.
