                                For humans, the estimated lethal dose (LD50) of theobromine, the primary compound in chocolate, is extremely high—around 1,000 milligrams per kilogram of body weight. This means the question of how much dark chocolate is toxic to humans is largely theoretical, as a fatal overdose requires an almost impossible amount to consume.
