<p>Use of dietary supplements in sports has increased worldwide and is becoming increasingly relevant in adolescent populations. Creatine is one of the most extensively studied ergogenic aids and is widely used in both recreational and competitive sports. In adults, creatine is well established to improve strength and high-intensity performance. In adolescents, however, evidence is limited. Some studies and systematic reviews suggest potential improvements in anaerobic performance, but the findings are inconsistent and based on small sample sizes and heterogeneous study designs. Robust long-term data on safety, particularly regarding growth and development, are lacking. In the short term, creatine appears to be well tolerated in healthy adolescents, with generally mild side effects. Overall, the available evidence in adolescents is insufficient, and no general recommendation for supplementation can currently be made; use should only be considered under medical supervision and after careful individual risk–benefit assessment.</p>
