I remember my first ice-cold Pepsi on a scorching summer day. That distinctive fizz, the caramel color swirling as I poured it over ice, and that unmistakable kick of energy that came after a few sips. Little did I know then what was giving me that gentle buzz β caffeine, the world's most popular stimulant, measured precisely at 38 mg per can.
The Pepsi Story
Back in 1893, North Carolina pharmacist Caleb Bradham created what he called "Brad's Drink" which is a mix of caramel, kola nuts, lemon oil, and nutmeg. This concoction became so popular locally that Bradham renamed it "Pepsi-Cola" and began selling it beyond his pharmacy.
Today, Pepsi stands as a global beverage giant. The modern formula includes carbonated water, high fructose corn syrup, caramel color, sugar, phosphoric acid, caffeine, citric acid, and natural flavors. A standard 12 oz can contain 150 calories, 30 mg of sodium, and 41 g of added sugars.
Pepsi's Caffeine Content
A scientific study published in the Journal of Food Science analyzed the caffeine contents of numerous carbonated beverages using high-performance liquid chromatography. The research found that a 12 oz serving of Pepsi contains 38.9 mg of caffeine, slightly higher than Coca-Cola at 33.9 mg but lower than Dr Pepper at 42.6 mg per 12 oz serving.
Here's how caffeine content scales with Pepsi container sizes:
- 12 oz can: 38 mg
- 16 oz can: 51 mg
- 16.9 oz bottle: 53 mg
- 20 oz bottle: 63 mg
For those watching their sugar intake but wanting more caffeine, Pepsi Zero Sugar offers 69 mg per 12 oz can. And that is almost double the caffeine of regular Pepsi. Diet Pepsi falls in between with approximately 35 mg per 12 oz serving.
How Does Pepsi Compare to Other Caffeinated Drinks?
Coffee remains the caffeine champion among common beverages. According to Mayo Clinic data, an 8 oz cup of brewed coffee contains about 96 mg of caffeine. It's nearly four times the amount in the same volume of Pepsi.
Other popular sodas and their caffeine content per 12 oz include:
- Mountain Dew: 54.8 mg
- Diet Mountain Dew: 55.2 mg
- Diet Coke: 46.3 mg
- Dr Pepper: 42.6 mg
Interestingly, store-brand sodas typically contain less caffeine than their name-brand counterparts. For example, Walmart's Sam's Cola contains only 12.7 mg of caffeine per 12 oz. And that is about a third of what's in Pepsi.
Pepsi with Coffee
Pepsi recently joined the coffee-infused soda trend with Pepsi CafΓ©. This hybrid beverage packs roughly twice the caffeine of regular Pepsi. It positions itself as an alternative to traditional energy drinks.
A recent study published in the journal Beverages found that many caffeinated beverages contain different amounts of caffeine than what's indicated on their labels. The research noted variations of up to Β±16 mg per serving in energy drinks. This highlights the importance of accurate labeling of caffeine content in beverages to help consumers make informed choices.
Should You Be Concerned About Caffeine in Pepsi?
For most healthy adults, moderate caffeine consumption (up to 400 mg daily) appears safe. A single can of Pepsi contributes less than 10% of this limit. However, certain groups should exercise caution:
- Children and teenagers should limit caffeine intake
- Pregnant or breastfeeding women should consult healthcare providers
- People with certain medical conditions like heart problems, high blood pressure, or anxiety disorders may need to restrict caffeine
Beyond caffeine concerns, the sugar content in regular Pepsi deserves attention. With 41 grams of sugar per 12 oz can, regular consumption may contribute to health issues including increased blood pressure, inflammation, weight gain, and elevated risk factors for heart disease.
The Case for Better Caffeine Labeling
Currently, the FDA doesn't require food and beverage manufacturers to list caffeine content on their products. A study published in the Journal of Caffeine Research argues that this represents "a missed opportunity for promoting personal and public health".

Now you know exactly what you're getting in that fizzy can of Pepsi! With 38 mg of caffeine in a standard 12 oz can, Pepsi gives you a mild pick-me-up without going overboard. That's way less than your morning coffee but enough to notice.Β
