In the afternoon, you invite a friend to grab coffee, only to be politely turned down with "I'm afraid I won't be able to sleep tonight"—and instead, they order a milk tea. Sound familiar? But what you may not know is that milk tea also contains caffeine. Caffeine is a natural stimulant found widely in more than sixty plants, including coffee beans, tea leaves, kola nuts, and cacao beans, and it also appears in synthetic form in medications, energy drinks, and even chewing gum. Caffeine content varies considerably across different beverages: a roughly 225-gram cup of coffee contains 95 to 200 milligrams, a 340-gram can of cola about 35 to 45 milligrams, a 225-gram can of energy drink about 70 to 100 milligrams, and a 225-gram cup of tea between 14 and 60 milligrams. This article walks you through how caffeine is absorbed in the body, when it peaks, and its half-life, as well as which factors determine how quickly it is fully metabolized, helping you schedule your coffee and milk tea more scientifically.
