How much caffeine is in Coke? How much caffeine is in Diet Coke?

Caffeine is one of the ingredients that helps give Coca-Cola its unique great taste.

People are often surprised when they learn that the amount of caffeine in Coke or Diet Coke is much less than in the same-sized coffee. Coke’s caffeine content is 34mg for a 12-oz can, and Diet Coke caffeine content is 46mg. That’s three to four times less than coffee! The same-sized coffee, in this case a 12-oz cup, has 140mg or more.


Which soda has the most caffeine?

Surge, our citrus-flavored soda, has the most caffeine of our sodas. It has 69mg of caffeine in a 16-oz can. While it has the most caffeine, you might be surprised to learn that it still has much less caffeine than in the same-sized coffee (similar to Coke and Diet Coke).

In case you're wondering, while not considered a soda, energy drinks also have caffeine. Be sure to check how much caffeine there is. It's listed on our products next to the Nutrition Facts label. For instance, the amount of caffeine in Monster Energy (original) has 160mg per 16-oz can.


How much caffeine is too much?

The U.S. FDA says healthy adults can have up to 400mg of caffeine a day without having adverse health effects. Limits may be less for children and pregnant women.

That would be like having eight 12-oz cans of Diet Coke, four to five cups of coffee (1 cup = 8oz) or 20 squares of dark chocolate (1 square = 1oz).

What is caffeine anyway?

Caffeine is a mild stimulant and can affect people differently on how much they’ve consumed and how often they consume it. Caffeine is used in our products, like Coca-Cola, to give it a slight bitter taste.

It is also found in many beverages and foods, such as coffee, tea, colas and chocolate.
