Buying for a child

Age range from the brand: Ages 3+ (ages 3: half scoop; 4+: one scoop). This label starts below age 4. We don’t tag products for children under 4: please ask your pediatrician about this one. 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
