Founding year



Institut AllergoSan was founded in 1991 and its headquarters are in Graz, Austria. The company researches and develops medically relevant probiotics and dietary supplements made from natural substances such as prebiotics, plant extracts, vitamins, and mineral substances.

The company’s focus is on researching the gut microbiota and the optimisation of the human microbiome. In 1993, bacterial preparations were introduced alongside allergen-free foods and orthomolecular dietary supplements, and it was in 1995 that the first in a series of multispecies probiotics was developed under the OMNi-BiOTiC® brand.

In the years that followed, Institut AllergoSan became an international competence centre for intestinal health, initiating numerous research projects, as it continues to do today, on various medical indications together with scientists from Germany and abroad. Institut AllergoSan follows an integrative approach that aims to strengthen the foundations of human health with natural substances before problems develop. Over the past 10 years, Institut AllergoSan, with its umbrella brand OMNi-BiOTiC®, has succeeded in becoming the market leader in Austria and Germany in the field of medically relevant probiotics. The award-winning company is now represented with its products in 40 countries around the world and employs over 250 people.
