Why Is There Caffeine In Pepsi?

Caffeine was originally a natural ingredient in colas. The caffeine came from the kola nut which is no longer a component in these beverages. Manufacturers state that they add caffeine to cola, today, for flavoring. It is said to produce a bitter flavor that helps balance the sweetness and gives cola its unique taste.

Of course, caffeine is also a stimulant that helps keep us awake and alert. This certainly helps sales to some degree, although, soda manufacturers likely won’t admit it.

Caffeine Comparison

Below you will find a comparison of Pepsi’s caffeine to other caffeinated beverages of the same size. The level of caffeine in Pepsi is similar to other colas but much lower than what you find in numerous coffee and energy drinks.

Be aware that the U.S. Food and Drug Administration states that most adults can drink up to 400 milligrams of caffeine per day and be safe. That’s about 10.5 cans of Pepsi a day assuming no other caffeine is consumed. We think it’s safe to say that most people don’t come close to drinking that amount.
