Even though we know that eating brown rice is good for our health, it is a difficult habit to maintain. That’s why we created Genmai Koso, an easy way to have brown rice.
Genmai Koso F100 is a food made by fermenting brown rice, brown rice germ, and bran, which are rich in minerals and vitamins, with Koji culture (Aspergillus oryzae), a fungus found in Japan. It serves as the base for all our Genmai Koso Hi-Genki products and is also considered to be the “starting point” for using our unique and advanced fermentation technology.
Furthermore, this product is also made 100% from ingredients that have been academically researched for over 20 years. It has more nutritional value than brown rice alone and is expected to have a number of functions to keep your body healthy.
