Institut AllergoSan

Institut Allergosan with its headquarters in Graz (Austria) was founded in January 1991. For 25 years now it has been involved in the research and development of products made of natural substances such as probiotic bacteria, plant extracts and minerals.

Thanks to our intensive cooperation with internationally recognised researchers from the fields of medicine, biology, pharmacology and biochemistry, we have succeeded in building up a well-known centre of research and excellence for natural medicine. 


Institut Allergosan pursues a holistic approach: it aims to strengthen the foundations of people’s health before illness can arise - and does so by using what nature itself has made available to us. 

Our work focuses on offering our customers scientific innovations which are dedicated to human beings as an overall system and to nature. Our declared aim is to find the best solutions for complex health issues, combining scientific innovation and the safety of the user while doing so. For the greatest possible benefit in terms of our customers’ health.

 “Our goal is to develop scientific innovations which are dedicated to the entire human being and which involve nature in the process of restoring health.”“


We are convinced that one day it will be possible to prevent the majority of diseases and mental suffering with timely precautionary measures using natural means. Then we will only have to use chemical medicines in those cases where they are really needed for seriously ill patients. In addition, treatment will be affordable for everyone and we won’t have to be afraid of having a two-class medical system - one for the rich and another for the poor. 

At the heart of this vision is a healthy gut. The future belongs to probiotic medicine.

Company history

How it all began…

Institut Allergosan was founded in 1991. It was the brainchild of 20 doctors who needed allergenically ‘clean’ foods and medicines for their patients, and who enlisted the help of the pharma‎cist Friedrich Frauwallner to this end. The majority of our customers at that time had been struggling for years with chronic skin diseases such as neurodermatitis and psoriasis, and had now found sudden relief from their suffering.

In 1992, Anita Frauwallner took over the management of the institute and pressed ahead with a special holistic medical approach based on the hypothesis that a person's health is essentially founded on a healthy digestive system. As early as 1993 our first probiotics were introduced alongside allergen-free and orthomolecular foods.

The following years…

Institut Allergosan was enormously successful with the JAVACELL skin care series which it developed against neurodermatitis and psoriasis. It was precisely the intensive contact to the customers of their pharmacy in Graz which enabled the Frauwallners to observe in detail how an holistic health concept – internal and external – could help even those who had been suffering for decades to live normal lives again.

After the sale of the pharmacy at the end of 2001, Anita Frauwallner focused increasingly on her research work at Institut Allergosan. Probiotic food supplements and the combination of the strength of plants with orthomolecular vitamins and minerals became a recipe for success. After years at various universities in Austria and abroad, her own son Bernd Assinger also joined the management of the institute in 2006 to give a further boost to its success.Our recipe for success

Institut Allergosan can look to the future with the highest level of motivation thanks to its backbone consisting of an excellent team of experienced and new staff who – thanks to constant training and a lot of positive spirit – provide competent support to all those interested in the firm’s products.

A future which belongs not to an industry which solely deals in chemicals, but the development of a biological medicine which focuses on regeneration and prevention.


The institute has been working together with international physicians and scientists on the topic of intestinal functioning and health for more than 20 years, and can refer to an outstanding range of supporting studies. Knowledge that has been a matter of course in holistic healing practices such as traditional Chinese medicine, the Ayurveda, or the teachings of Hildegard von Bingen, has now been rediscovered and scientifically justified in research findings. The use of medically relevant probiotics for treating antibiotics-associated diarrhoea has been known for some time, and the products of Institute Allergosan have been made known to a broad medical public by a large-scale publication in the American Journal of Gastroenterology in 2008.

Particularly significant today are those works of basic research which can possibly offer new treatment approaches for people suffering from typical "lifestyle diseases" such as adiposity or stress-induced depressions in the next few years.
