Nutrisport energy Boost provides complex carbohydrate, to give a quick but prolonged release of energy. Energy for training and competition is stored in the muscles as a carbohydrate, called glycogen. Taking the right form of carbohydrate before and after training/competition can have a marked effect on energy and performance.After Training: Research has shown that the replacement of muscle energy (glycogen) occurs fastest within 45 minutes of finishing your exercise. So the drink should be taken immediatelty after the exercise.Before Training: You need to ensure that the blood suagar remains at a good level. Taking sweets, sugar or glucose causes your body to release insulin; this lowers blood sugar and lessens energy.Nutrisport Energy Boost can be taken before and ruing exercise, but mix it weakly so that it can be easily absorbed.Suitable for Vegetarians & Vegans.
