Most healthy adults can safely consume up to 400 milligrams (mg) of caffeine per day. This is roughly equivalent to the caffeine in four cups of brewed coffee, 10 cans of cola, or two energy shot drinks. However, sensitivity to caffeine varies between individuals, and some may need to consume less to avoid side effects. Pregnant or breastfeeding women, children, and people with certain health conditions should limit their caffeine intake further and consult healthcare professionals for personalized advice.
