From Coffee Beans

Caffeine is a natural stimulant found in the leaves and seeds of coffee plants. It is extracted from coffee beans through various processes, often involving hot water and solvents. The resulting caffeine is typically a white, crystalline powder.

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, sodas, and some coffee-flavored products.

Caffeine is permitted in food by the FDA. JECFA has evaluated caffeine and set an acceptable daily intake. Consuming moderate amounts of caffeine is generally considered safe for most adults and may be associated with some health benefits, such as improved cognitive function. However, high intake can lead to anxiety, insomnia, and rapid heart rate in sensitive individuals. Research on caffeine's long-term health effects is ongoing.
