Caffeine Absorbed in the Mouth Peaks Faster Than a Pill
Caffeine absorbed through chewing gum reaches peak plasma levels significantly faster (44.2-80.4 min) compared to capsule formulation (84.0-120.0 min), suggesting buccal mucosa absorption. The gum formulation provides comparable systemic bioavailability to capsules while enabling earlier onset of pharmacological effects, which is advantageous for rapid reversal of alertness deficits from sleep loss.
