Theobromine is a methylxanthine alkaloid, structurally similar to caffeine and theophylline. It consists of a xanthine core with two methyl groups (-CH₂) attached at the N-3 and N-7 positions. Its purine ring system is similar to a nucleotide which contributes to its biological activity.

Its name comes from the Greek word 'theo' meaning 'god', and 'Broma', meaning food, making Theobromine the 'food of the gods'. It's found in cocoa & chocolate & is the primary alkaloid in cacao beans where it imparts the bitter taste of dark chocolate. As might be expected from its similarity to caffeine, it imparts chocolate's stimulant effects on metabolism, albeit more weakly. As a central nervous system stimulant it improves mood by increasing serotonin and dopamine levels. It may have cardiovascular benefits by acting as a vasodilator and a diuretic which can lower lower blood pressure.

Theobromine's stimulant properties do incur safety issues in humans. In moderate amounts (from chocolate and cocoa), theobromine is safe and beneficial but high doses can cause nausea, headaches, restlessness, and rapid heart rate. Individuals with heart conditions should limit intake. Theobromine is toxic to dogs & cats. It can cause vomiting, seizures, heart arrhythmia, and death. Do not leave opened packages chocolate within reach of pets.

Some coffee enthusiasts have even bought custom imprinted glass beakers to enjoy their favorite brew.
