Creatine for kids is generally not recommended, because more studies are needed to confirm whether it is completely safe for for children or teens under 18.
However, current research suggests that taking creatine in recommended doses does not appear to be harmful, especially for older children and teenagers.
In some cases, creatine supplementation may be appropriate for young athletes who are closely monitored by a doctor, coach, and registered dietitian.
Children and teenagers should not take creatine supplements without professional guidance. A pediatrician, sports medicine doctor, or registered dietitian can help determine whether creatine supplementation is appropriate and safe.
