The caffeine content in various Pepsi products, namely Pepsi, Diet Pepsi, and Pepsi Max (also referred to as Pepsi Zero Sugar), differs based on the type and size of the serving.

How caffeine is in Regular Pepsi?

Regarding Regular Pepsi, a standard 12 fluid ounce (fl oz) can typically contains approximately 37 to 38 milligrams (mg) of caffeine.

If one opts for a larger serving, the caffeine content increases correspondingly; a 16.9 fl oz bottle holds about 53 mg, and a 20 fl oz bottle contains around 63 mg of caffeine.

How much caffeine is in Diet Pepsi?

Turning to Diet Pepsi, this iconic drink has a marginally lower caffeine content in comparison to its regular counterpart, which is surprising because Diet Coke is found to have more caffeine than regular Coke .

In a 12 oz serving, Diet Pepsi contains roughly 35 to 36.7 mg of caffeine. This slight reduction in caffeine might appeal to those who are mindful of their caffeine intake but still enjoy the taste of Pepsi.

How much caffeine is in Pepsi Max?

As for Pepsi Max, also known as Pepsi Zero Sugar, it stands out for having a significantly higher caffeine content compared to Regular Pepsi or Diet Pepsi.

For example, a 12 oz serving of Pepsi Zero Sugar (or Pepsi Max) boasts approximately 69 mg of caffeine, almost double the quantity found in Regular Pepsi.

It's worth noting, however, that there appears to be some inconsistency in the reported figures for caffeine content in Pepsi Zero/Pepsi Max. One source suggests that a regular Pepsi typically contains about 107 mg of caffeine in the same serving size, which seems rather high and might be a reporting error.

Is there more caffeine in Pepsi than coffee?

No, there is less caffeine in Pepsi than coffee. In contrast to other caffeinated beverages like coffee, the caffeine content in Pepsi products is relatively low.

For example, a typical cup of brewed coffee can contain between 95 to 200 mg of caffeine per 8-ounce serving, depending on the coffee type and brewing method.
