Caffeine Content: Coke Zero vs. Diet Coke

6 years ago

I ordered Coke Zero at a restaurant last night. My waitress told me regular Coke Zero doesn`t contain caffeine, but I figured she was mistaken about that. So today when I went to buy a drink during a break at work I decided to compare the caffeine content between 20 fl. oz. bottles of Diet Coke and Coke Zero.

Both drinks contain caffeine. No surprise there. What surprised me was the difference in caffeine content between the two drinks.

*Additional note* I have also checked how much caffeine regular Coca-Cola contains since I am seeing a lot of comments by people who haven`t tried Coke Zero or Diet Coke yet. :)

Coke Zero contains 58mg of caffeine per 20 fl. oz.
Diet Coke contains 76mg of caffeine per 20 fl. oz.
Coca-Cola contains 58mg of caffeine per 20 fl. oz.

A surprising 18 mg difference between Coca-Cola, Coke Zero and Diet Coke! That may not seem like much, but it is something soda drinkers may want to keep in mind if they are also trying to monitor their caffeine intake.

Just for the record, I prefer the taste of Coke Zero over Diet Coke. :) And I can`t remember the last time I drank a regular Coca-Cola.

Comment if any of this is surprising to you as well. Or if you notice yourself feeling more caffeinated when drinking Diet Coke.
