Creatine supplementation is common among male collegiate athletes, with many starting in high school. Peer information and perceived strength gains drive its use, though dosing is often unclear.

Area of Science:

  • Sports Nutrition
  • Exercise Physiology
  • Dietary Supplementation

Background:

  • Creatine is a popular dietary supplement for athletes.
  • Understanding its use patterns in collegiate athletes is crucial for health and performance guidance.

Purpose of the Study:

  • To determine the prevalence and patterns of creatine use among NCAA Division I athletes.
  • To identify sources of information and perceived effects of creatine supplementation.

Main Methods:

  • Anonymous descriptive survey distributed to collegiate varsity and junior varsity athletes.
  • Collected self-reported data on creatine use, dosing, information sources, and perceived effects.

Main Results:

  • 28% of 806 surveyed athletes reported creatine use; 48% of men vs. 4% of women.

  • One-third of users started creatine in high school; peers were primary information sources.
  • Athletes expected and perceived increased strength and muscle size as primary benefits.

    • Conclusions:

    • Creatine use is prevalent in male collegiate athletes but minimal in females.
    • Peer influence and perceived ergogenic benefits drive creatine supplementation.
    • Further research is needed to understand long-term use patterns and optimal dosing.
