Understanding Caffeine in Drinks

Caffeine is a natural or synthetic stimulant found in beverages like coffee, tea, energy drinks, and sodas. Natural caffeine comes from plants (e.g., coffee beans, tea leaves), while synthetic caffeine is lab-produced for energy drinks. Caffeine content varies by drink type, preparation, and serving size. For those asking, “What is caffeine?”, it’s a compound that boosts alertness, focus, and energy by stimulating the central nervous system. The FDA recommends a safe daily limit of 400 mg for most adults, equivalent to about 4 cups of brewed coffee.
