Some volleyball players think they may need to take supplements to perform better. That’s a myth. Vitamins and minerals do NOT deliver energy. Your energy/calories come from balanced meals consisting of fruits and vegetables, whole grains, and low-fat protein, dairy, and healthy, unsaturated fats. A dietary supplement is a vitamin, mineral, herb, botanical, amino acid, metabolite, constituent, extract, or any combination of them. Daily multivitamin supplements are legal for athletes and may be used to make sure you are getting adequate amounts of all essential nutrients. Most other supplements are banned by the NCAA.



The most popular supplements that volleyball players are consuming include:

  • Creatine
  • Caffeine
  • Beta-hydroxy-beta-methylbutyrate (HMB)
  • Dehydroepiandrosterone (DHEA)

*Although the dosage is given, please note that these supplements are banned by the NCAA.
