Health authorities and organizations have established guidelines regarding safe daily caffeine consumption for adults. The European Food Safety Authority (EFSA) suggests a limit of 400 milligrams for healthy adults, noting that pregnant or breastfeeding women should restrict intake to 200 milligrams. Excessive consumption can lead to physical symptoms such as rapid heartbeat, anxiety, and sleep disruption.

Similarly, the American Heart Association (AHA) identifies up to 400 mg of caffeine as safe for most adults. Research indicates that moderate coffee consumption, specifically between two and four cups daily, may be associated with a lower risk of stroke, heart failure, and coronary disease. Experts emphasize that because caffeine content varies by preparation method and concentration, individuals should monitor specific milligram intake rather than just the number of cups consumed.
