Our clinical studies

We carried out our first clinical glycemic index study in cooperation with the 2nd Department of Internal Medicine, 3rd Faculty of Medicine and University Hospital Královské Vinohrady, Prague. In this study, we focused on determining not only the glycemic index (GI), but also the insulin index (II). Both parameters are used to evaluate the burden of food on metabolism and assess their suitability for diabetics and patients with other metabolic problems. The glycemic and insulin responses of Mana Drink were tested on 10 subjects, and compared with the equivalent carbohydrate dosage of a reference food (glucose).

According to our studies, we can characterize Mana Drink as a relatively low carbohydrate burden. The glycemic index of Mana Drink is 29 and the insulin index is 41. In comparison with other food, Mana Drink has a very low score. The composition of Mana Powder is exactly the same apart from a few ingredients, so we believe that its glycemic and insulin indexes will be very similar.

Here you can find the clinical studies of Mana Drink.
