The history of Bio-Strath

How it all began

When he was young, company founder Fred Pestalozzi suffered from Meniere's syndrome - a disease of the inner ear that causes dizzy spells and whistling in the ears. By chance he came across the concentrated herbal yeast preparation of the German chemist Dr. phil. nat. Walter Strathmeyer at that time - and thanks to him he was fully able to work again after only a few months. Pestalozzi was so enthusiastic about this personal success and the many positive reports from relatives and acquaintances that he founded Bio-Strath AG in 1961.

Family business since 1961
