Pepsi was developed in 1893 and has evolved considerably since its early days. Initially introduced as a healthful digestive aid, Pepsi-Cola quickly gained popularity and became known for its distinctive, sweet taste. Over the decades, Pepsi has undergone numerous changes in branding and product formulation. Today, it is available in many sizes—from 12 fl oz cans to 2-liter bottles—and in a variety of flavors including Wild Cherry, Lime, Ginger, and more. In addition, PepsiCo offers caffeine-free versions for those who wish to avoid caffeine.

Below is a table summarizing the caffeine content in Pepsi by serving size:

Insights and Statistical Analysis
Several studies have explored the effects of caffeine on the body. According to research published in the American Journal of Clinical Nutrition, moderate caffeine consumption can enhance alertness and cognitive function without causing significant adverse effects when consumed within safe limits. The Mayo Clinic suggests that a daily caffeine intake of up to 400 mg is safe for most healthy adults. With a 12 fl oz can of Pepsi containing approximately 38 mg of caffeine, it forms only a small part of the daily limit, making it a suitable option for those who prefer a mild energy boost.
