Vitargo is a huge carbohydrate molecule compared to ordinary carbohydrates used in sports drinks. Because of this Vitargo is more difficult to dissolve. Use a blender ball in your shaker bottle, and fill the bottle/shaker with 200 ml of water, then add the powder and shake vigorously for 30 seconds. Add 500-600 ml of water and shake vigorously for another 30 seconds. Always make sure to add the powder to the water, and not the other way around.
