Your little champ isn't just physically active, he's also doing a lot of thinking. That means he's also using more energy than you might notice. 
The fact is: focus, concentration, and problem solving also require energy – just like running around and playing sport. And if he doesn't have enough energy, it can spell trouble for his alertness in class and ability to finish homeworks and review for exams. 
Give him new MILO with Champion Energy Nutrients. It has Protomalt, Vitamin B Complex and Iron to help release energy for physical and mental activities. Help him become a champion on the court and in the classroom.
