What Is Diet Pepsi and Does Diet Pepsi Have Caffeine?

Before determining whether Diet Pepsi contains caffeine, one should know what Diet Pepsi is. Diet Pepsi is a low-calorie, sugar-free alternative of the regular Pepsi. It came into being in 1964 as a healthier option for those who wish to enjoy the bubbly flavor of cola without added sugar and calories.
Diet Pepsi contains the sugar substitutes aspartame and sometimes acesulfame potassium (depending on where you live) and is marketed as diet cola.
According to market reports, Diet Pepsi has long been a leading diet cola brand worldwide and is marketed as a “diet” drink.

Does Diet Pepsi Contain Caffeine?

Yes. Diet Pepsi contains caffeine. A regular 12 fl oz (355 ml) can of Diet Pepsi provides approximately 35 mg of caffeine. This is slightly less than regular Pepsi, which contains about 38 mg of caffeine per 12 oz can.
So, in answer to does Diet Pepsi have caffeine, . . . yes it has caffeine, but only a small amount compared to coffee or energy drinks.

Why Does Diet Pepsi Have Caffeine?

Diet Pepsi contains caffeine because it is a natural stimulant found in coffee, tea, and other cola beverages, and caffeine is included in most soft drinks for the following reasons:

1. Flavor: Caffeine is also slightly bitter and can enhance the sweetness of soda.
   
2. Stimulant: It also produces some energy, and thus, can help promote alertness and reduce fatigue.
   
3. Consumer Expectation: It is normal to expect some amount of caffeine to be included in cola-type sodas, and therefore, the absence of caffeine would change the flavor and the mouthfeel of the product.

Therefore, while Diet Pepsi’s caffeine content is less than that of a cup of coffee, caffeine plays an important role in the consumer experience in relation to the flavor and mouthfeel of the beverage.

Caffeine Content Comparison

To better understand does Diet Pepsi have caffeine let’s compare its caffeine content to some other commonly read beverages:

Beverage Caffeine (per 12 oz)

• Diet Pepsi 35 mg
• Regular Pepsi 38 mg
  
• Pepsi Zero Sugar 69 mg
  
• Diet Coke 46 mg
  
• Coca-Cola Classic 34 mg
  
• Mountain Dew 54 mg
  
• Coffee (brewed) 95-165 mg
  
• Green Tea 25-45 mg

We can see that Diet Pepsi does contain caffeine and in lower amounts than coffee or even energy drinks for example. It’s also lower than in some of the other sodas, such as Diet Coke.

Is the Caffeine in Diet Pepsi Safe?

For healthy adults, moderate levels of caffeine (up to 400 mg a day) can be taken safely, says the U.S. Food and Drug Administration (FDA). That would be more than 11 cans of Diet Pepsi in one day — much more than most individuals would drink.
Some individuals are more sensitive to caffeine, however, and would experience symptoms such as:
