For people under 13 there are no protein shakes that will not harm them. As a 12 year old is still growing, protein shakes can have harmful side effects. This means that they would get protein from different sources, such as: eggs and cow's milk. Red meat also works however it takes a while to digest which obviously makes it a bad alternative for a protein shake (protein shakes are quickly processed by the body, hence the appeal). If you want a child to perform well try putting them on the diet in the related link. It is very effective however it will require a lot of discipline.
