## Description

We’re providing “Koso-drink", a fermented beverage created about 100 years ago in Japan. It's normally made from over 50 vegetables and fruits but R's KOSO is made from over 100 different fruits, vegetables, plants, a special combination of sake yeast, lactic acid bacteria, and koji. Koso-drink is rich in probiotics and prebiotics that help digestion and gut health. It has traditionally been used by those who didn’t have access to nutrient-dense foods but has become a popular choice among the young and health-conscious for Fermented drink Cleanse called Koso-Cleanse. "Koso" means enzyme in Japanese for real, but it is used for fermented drinks and foods that are using enzymes through the making process. The benefits of Koso foods and drinks are clarified from some researches like below. "The enzyme-food contained abundant functional ingredients, i.e., polyphenols, dietary fiber, and indigestible dextrin. The enzyme-food indicated high antioxidant activity and suppression of AGE (glycated protein) formation, which is thought to be responsible for the pathogenesis of various lifestyle diseases. The feeding of enzyme-food in rats suggested that the possibilities of body fat reduction, improvement of bowel movements, and improvement of carbohydrate and lipid metabolism. So the products commonly called ‘enzyme-foods’ may be beneficial for health maintenance because of functional ingredients, not food-enzyme, contained in them." Shizuka HASE-TAMARU et al. (2018). “The in vitro and vivo evaluation of products so called ‘enzyme-foods’“
