Caffeine gum is one of the better-studied alternative caffeine formats, largely thanks to U.S. military research. In a well-known study, caffeine from gum reached peak blood levels in about 44–80 minutes vs 84–120 minutes for capsules, with similar total exposure (review, PMC). Commercial gums range from about 10 to 100 mg of caffeine per piece (OPSS).
