What Is Pepsi?

Pepsi is a soft drink and product of PepsiCo, Inc. It was created in 1893 by Caleb Bradham, a pharmacist in New Bern, North Carolina, as “Brad’s Drink.” This initially featured a blend of caramel, kola nuts, lemon oil, nutmeg, sugar, water, and other additives. It was later renamed “Pepsi-Cola” and went from being sold solely out of Caleb’s pharmacy to expanding via other vendors and pharmacies across the state, country, and globe. (1)

Does Pepsi Have Caffeine?

Yes, Pepsi has caffeine. The full list of ingredients for 12 fluid oz. of Pepsi includes carbonated water, high fructose corn syrup, caramel color, sugar, phosphoric acid, caffeine, citric acid, and natural flavor, with 150 calories, 30 mg of sodium, and 41 g of added sugars. 

It is recommended to limit your sugar intake to a max of one 12 fluid oz. can of soda daily.

It’s important to monitor your sugar intake, especially if you drink sodas (2).

The effects of added sugar intake – higher blood pressure, inflammation, weight gain, diabetes, and fatty liver disease – are all linked to an increased risk for heart attack and stroke.

It goes without saying that sugar is not the healthiest thing in the world, so take that into account when opting for drinks like this.

Final Thoughts

So, what’s the caffeine content of a can of Pepsi? There is 38 mg of caffeine in 12 fluid oz. of Pepsi. This comes naturally from the addition of kola extract. Pepsi is a sweet, crisp, and refreshing soft drink that has skyrocketed into a worldwide sensation via numerous celebrity endorsements and mainstream enthusiasm.


Pepsi is not healthy. It has a lot of sugar and calories without being a nutritious source of vitamins and minerals. Drinking too much soda can contribute to the development of cancer, dementia, diabetes, gout, heart disease, sugar addiction, tooth decay, and weight gain (3).

A cup of coffee, or 8 fluid oz., has 90 to 100 mg of caffeine. This is nearly four times the amount as in 8 fluid oz. of Pepsi, which has just 25 mg of caffeine. There is less caffeine in soft drinks vs coffee. For example, there is 28 mg of caffeine in Dr. Pepper and 23 mg in Coke Zero per 8 fluid oz. each. Even Mountain Dew has caffeine with 36 mg per 8 fluid oz.

There is 35 mg of caffeine in a 12 fluid oz. can of Diet Pepsi and 69 mg in a can of Pepsi Zero Sugar vs approximately 136 mg of caffeine in a traditional cup of coffee of the same amount.

I am a writer who delves into all manner of things related to coffee, cats, and characters. I started drinking coffee daily in university and now my entire work, life, and personality all revolve around procuring the perfect brew. I start every morning with yoga, French Press coffee, and some special creative time devoted to working on a magical cat café story... but, more on that later.
