According to The Mayo Clinic, a healthy adult can safely ingest approximately 400 milligrams of caffeine per day. If you go above that, you general health could be affected, including the quality of your sleep and other unpleasantness. With that in mind, Redditor SportsAnalyticsGuy created two charts listing some of the most popular products containing caffeine and how much you have to “ingest” to reach the 400 milligrams limit. The data you see in the graphs comes from the National Center for Biotechnology Information.
