Bio-Strath

Natural since 1961

Who we are

For over 60 years, we have been producing food supplements based on the unique Strath herbal yeast in Zurich. With great pleasure and commitment, we work every day to produce the best quality products and nutritional supplements according to GMP guidelines (good manufacturing practice). Natural raw materials, gentle processing according to the latest standards and processes, and compliance with strict manufacturing guidelines form the basis for this.

David Pestalozzi, CEO

Our guiding principle

"Professional competence, innovative action and committed work."

A harmonious combination of head, hand and heart - are the guiding principle of Bio-Strath, which is still independent of large corporations and focuses on healthy, rather than rapid, growth.

From production to shipment

Many years of experience and a great deal of know-how ensure that the Bio-Strath products leave the company in top quality and reach specialised trade. Take a look at our production facility and experience the filling of Strath liquid. The "Dave" filling machine can fill over 3000 bottles per hour. The bottles are then labelled and packed into folding boxes. They are then automatically packed into shipping cartons and palletised. Now Strath liquid is ready for worldwide shipping.
