If you like calorie drink mixes, this is the BEST option to try on all intensity workouts. Be careful on the amount of water you use and pay attention to that detail. 17oz or 500ml is the amount you are looking for. The mix is designed to be mixed with water with <40mg/L calcium content. Higher levels can affect how it’s dissolved. Maurten is careful to say that the functionality of this ratio is key for it to work well. Also, make sure you shake well until the solution dissolves. Drink it before, during and/or after your activity.
