Fermented Green Papaya Enzyme, known as Bio Normalizer is a bio-fermented food supplement using a traditional Japanese fermentation method. It was invented by Dr Akira Osato, PhD in 1969. It has been the top selling green papaya enzyme in Japan. 

Since 1969, there is a very unique history behind this product. It greatly contributed towards the patient's recovery from the radiation explosion in Chernobyl Ukraine in 1993 and the SARS outbreak in China in 2003. We have over 130 research papers about our product over the time, especially about Immunology.

We hope that Fermented Green Papaya Enzyme supports people's better health in the UK too.
