A HERITAGE FERMENTATION
Red koji — rice fermented with the Monascus family of yeasts — has centuries of history in East Asian food culture as a fermentation starter, natural colouring and traditional food. Its deep red colour, distinctive aroma and umami character made it a fixture long before it became a supplement.

Chitosan, a dietary fibre derived from crustacean shells. Rice bran extract containing policosanol, the plant fatty alcohols naturally present in rice bran. Pine needle extract, from a long East Asian and Korean herbal tradition. And olive leaf extract with its polyphenol hydroxytyrosol.
MADE IN JAPAN, CLEARLY LABELLED
