Caffeine From Natural Green Tea

Caffeine is a natural stimulant found in coffee beans, tea leaves, and cacao pods. In green tea, caffeine is extracted from the leaves of the Camellia sinensis plant. The extraction process typically involves using water or solvents to isolate the caffeine compound.

Caffeine is added 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 teas, where it serves as a functional ingredient to provide an energy boost.

In the US, caffeine is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. The FDA has also established limits for caffeine in certain products. Major health organizations like the WHO and EFSA have evaluated caffeine, noting its stimulant properties and potential effects on sleep and heart rate at higher doses. Evidence suggests moderate caffeine consumption is safe for most adults, but individual sensitivity varies.
