Abstract in brief

  • Low doses of caffeine, including amounts found in foods and over-the-counter drugs, can significantly improve alertness, reaction time, and vigilance without causing adverse effects like anxiety or impaired motor skills.
  • Even very small doses (32 mg) elevate blood caffeine levels enough to boost performance, highlighting how common dietary caffeine intake can positively influence mood and cognitive function.
  • The study found no negative behavioral effects at any dose tested, suggesting that low doses of caffeine are generally safe and beneficial for enhancing certain aspects of human performance.
