This level is relatively moderate compared to other caffeinated beverages such as coffee or energy drinks.

1.1. Overview of Caffeine in Pepsi

Caffeine is a naturally occurring stimulant found in coffee beans, tea leaves, and cocoa beans. It is added to Pepsi to enhance its flavor and provide a slight energy lift. The caffeine content in Pepsi is carefully regulated to ensure it is within safe consumption levels.

Source of Caffeine: Caffeine in Pepsi is typically derived from artificial additives and natural sources.
Purpose of Caffeine: It acts as a flavor enhancer and a mild stimulant.
Regulation: PepsiCo adheres to regulations regarding caffeine levels in beverages.
