                                The US Food and Drug Administration (FDA) recommends a daily caffeine intake of no more than 400 mg for healthy adults. Exceeding this limit, particularly by consuming 800 mg of caffeine, can trigger a range of severe and potentially dangerous physiological and psychological symptoms. This amount, equivalent to roughly eight cups of coffee, is well into the territory of caffeine intoxication.
