                                The U.S. Food and Drug Administration (FDA) generally considers up to 400 mg of caffeine per day safe for most healthy adults. However, the real question for many is: is 280 mg of caffeine safe, and how does that specific dose affect your body? The answer depends heavily on your individual health, sensitivity, and consumption habits.
