What is the maximum recommended total daily intake of caffeine for healthy adults?
Answer
400 milligrams
Health organizations generally advise that healthy adults cap their total daily caffeine consumption at 400 milligrams. This limit encompasses caffeine derived from all sources, including energy supplements, coffee, tea, and soda. Exceeding this amount significantly increases the risk of side effects such as palpitations, sleep disruption, and anxiety, as the body struggles to process the concentrated stimulant load.
