Do Pepsi, Coke and Other Cold Drinks Contain Caffeine?

Fizzy soft drinks like Pepsi, Coke, and other sodas are popular worldwide, seemingly made of water, sugar, carbon dioxide, and flavor. Their inclusion of caffeine, a stimulant typically associated with morning coffee, sets them apart. It’s worth noting that caffeine traditionally used to be a natural part of cola drinks, as soft drink manufacturers like Coca-Cola used the kola nut extract to prepare the drink, and caffeine is naturally present in the kola nut. Surprisingly, even extracts of the coca plant used to be included in Coca-Cola. Neither of these natural sources is used anymore, so it makes sense that the fizzy colas would include caffeine to invoke the missing flavor of the kola nut. In fact, this is the very reason provided by soft drink manufacturers.
