Caffeine From Green Coffee Beans

Caffeine is a natural stimulant found in coffee beans, tea leaves, and cocoa beans. When extracted from green (unroasted) coffee beans, it is typically a white, crystalline powder. The extraction process usually involves solvents to isolate the caffeine.

Manufacturers add caffeine to foods and beverages primarily for its stimulant effect, helping to increase alertness and reduce fatigue. It is commonly found in energy drinks, coffee-based products, and some sodas. It can also be used as a flavor enhancer in small amounts.

Caffeine is generally recognized as safe (GRAS) by the FDA for use in food. The FDA monitors caffeine levels in beverages. JECFA has evaluated caffeine and established an acceptable daily intake. Consuming moderate amounts of caffeine is generally considered safe for most adults, but high intake can lead to anxiety, insomnia, and rapid heart rate. Evidence on long-term health effects is mixed, with some studies suggesting potential benefits and others raising concerns about specific health outcomes.
