HOW IT ALL BEGAN
In his youth, the founder of the company, Fred Pestalozzi († August 4, 2014), suffered from Menière’s syndrome – attacks of dizziness and tinnitus (ringing in the ears). But then, quite by chance, he came across the concentrated herbal yeast preparation from the German chemist, Dr. chem. phil. Walter Strathmeyer. A few short months later, Pestalozzi was cured and raring to go.

He was delighted by this personal success and the many positive reports about the experiences of friends and family. Dr. Strathmeyer gifted him the recipe and the licence so that he could produce the natural herbal yeast-based food supplement himself.

So, in 1961, Fred Pestalozzi founded Bio-Strath AG in a two-room apartment on Zurich’s Langstrasse. In 1964, the company relocated to Herrliberg on Lake Zurich. The facility was extended to its present size in three construction stages. Fred Pestalozzi was guided throughout by the following four principles, which are still the mainstays of Bio-Strath AG today:

THE COMPANY PRINCIPLE
Preserving the natural state of the active substances
No addition of artificially produced substances
Natural preservation, no preservatives
Proof of efficacy using strict scientific criteria

In the production plant today, some 1.8 million units per annum are produced, mechanically bottled, labelled, packed and prepared for dispatch across Switzerland and the world.
