Buying for a child
Age range from the brand: Elementary and junior high school students (小中学生). Most kids get enough protein from food, and our score is built for adult protein powders, so a kids' nutrition shake scores lower on protein density by design. Check with your pediatrician before adding a shake. What to look for in a kids' protein shake
