Chewing gum
Traditional chewing gum is a soft, rubbery substance made from tree sap. Although it is not a natural source, manufacturers might add caffeine to their recipes. Due to this, chewing gum has become common among some sportsmen and those looking for an energy boost.
According to studies, caffeine in chewing gum is absorbed significantly more quickly than caffeine in capsules. This may be because the inner cheek's buccal mucosa cells quickly absorb it. Athletic performance is improved by caffeine. Chewing gum that contains caffeine may increase your alertness and attention span. Because of this, the National Collegiate Athletic Association (NCAA) has put caffeinated chewing gum and other sources of caffeine on its list of banned substances for athletes.
