In addition to the many nutrients, there are also some active ingredients in cacao. In relevant amounts, these include theobromine, theophylline, caffeine and epicatechin. The first two substances are methylxanthines and have a vasodilating effect, allowing the body to accumulate more oxygen. Epicatechin primarily stimulates the regions in the brain that are involved with perception and memory. Cacao also contains some neurotransmitters - biogenic amines - which stimulate the production of the happiness stimulants serotonin, endorphin and dopamine in the brain. The list of ingredients and active ingredients in cacao is much longer and new substances are still being discovered.
