                                According to the U.S. Food and Drug Administration (FDA), most healthy adults can safely consume up to 400 milligrams of caffeine per day. However, answering the question, "Is 350ml of caffeine a lot?" is misleading, as milliliters measure volume, not the milligrams of caffeine within that volume.
