Theobromine

Mild, smooth stimulant with cardiovascular and mood benefits. Less jittery than caffeine but also less potent.

A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.

Clinical studies show modest blood pressure reduction and mood improvement. Weaker CNS stimulant than caffeine (~10x less potent) but longer half-life. Effective bronchodilator in preclinical models.

• Mild, sustained stimulation without jitters
• Vasodilatory and blood pressure-lowering
• Mood-enhancing properties

100–500 mg daily. A 40 g dark chocolate bar contains roughly 200–300 mg.

• GI reflux
• Headache at high doses
• Mild diuresis

Toxic to dogs and cats. May cause reflux by relaxing the lower esophageal sphincter. Mild diuretic effect.

Often consumed as part of dark chocolate or cacao, making it hard to isolate theobromine-specific effects from other cacao components.
