STUDY: Caffeine Gum Enhances Athletes Performance

• The researchers gave caffeinated gum (400 mg caffeine, ≈ 4.1 mg/kg body weight) during a simulated half-time period to professional rugby players. 

• They measured physiological (blood lactate, hormones like testosterone & cortisol) and performance (repeated sprints, cognitive tests) effects.

• Findings:

  • No significant improvement in sprint performance compared to placebo. 

  • However, salivary testosterone increased by ~70% in the caffeine group vs placebo. 

  • Cortisol levels didn’t change much.

  • Cognitive performance (reaction time, Stroop test) showed no significant differences. 

What You Can Highlight (With Caution)

• Evidence-based claims: “In a controlled trial, chewing caffeine gum during a half-time period increased testosterone levels (a marker often associated with motivation & intensity).”

• Contextual framing: Emphasize “may support motivation”, “potential to support performance under certain conditions”, rather than overpromising.

• Linking to research: Include a “Research / Studies” section on your product page that cites this and similar trials (with short summary).

• Use in routines: “Use our gum between workout sets or during breaks — as suggested by sports research — to support hormonal response and mental sharpness.”

• Transparency & disclaimers: Make sure to note that results may vary, and that the study was in athletes under controlled conditions.
