We work at the intersection of science and sustainability.

Siranius is a Swiss-based bioscience company operating at the intersection of biotechnology and everyday health, transforming lignin’s natural defence system into safe and effective gut health products. 

From the wheat straw we source to the production we facilitate, purpose and circularity are embedded into every step of our journey. We’re constantly looking for smarter ways to reduce impact while increasing value for people’s health. Every decision we make is guided by the belief that sustainability isn’t a feature. It’s the foundation.

Our vision is to make lignin derived health solutions a trusted standard in nutraceuticals and functional wellness, valued not only for their natural origin, but for their proven performance in human health.

We work to  unlock the bioactive power of lignin for human health, creating safe, effective, and sustainable solutions that support gut balance, immunity, and resilience.

Siranius is a company within the Tanovis Group – an expanding group of ventures that turns lignin’s scientific potential into tangible results. Each venture extends the Tanovis lignin platform into a new field, applying the same core technology in ways that improve animal health, advance material performance, and enhance human wellbeing.

Tanovis’ pioneering work with plant-based polymers forms the scientific backbone of our own development, giving us a proven platform to advance human health solutions with confidence.
