Caffeine From Black And Green Tea

Caffeine is a natural stimulant found in the leaves and seeds of many plants, including tea leaves. Black and green tea are made from the leaves of the Camellia sinensis plant. The caffeine is naturally present in these leaves and is extracted for use as an ingredient.

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, tea, and some snack bars.

Caffeine is generally recognized as safe (GRAS) by the FDA when consumed in moderation. The World Health Organization (WHO) and the European Food Safety Authority (EFSA) have evaluated caffeine and noted its stimulant effects. High intake can lead to jitteriness, anxiety, and sleep disturbances in some individuals, while moderate intake is generally considered safe for most adults. Evidence on long-term health effects is mixed, with some studies suggesting potential benefits and others raising concerns about cardiovascular health.
