Psychopharmacology of theobromine in healthy volunteers
It is concluded that theobromine at normal intake ranges may contribute to the positive effects of chocolate, but at higher intakes, effects become negative.
Ergogenic Effects of Intake of Salbutamol, Caffeine and Theobromine on Non-Asthmatic Subjects
Overall, salbutamol, the intake of which is restricted by WADA, did not have an ergogenic effect on athletes, while caffeine and theobromine, the usage of which are not controlled at all in sports competitions, had a performance enhancing effect on Athletes, according to the results.
Exploring cocoa properties: is theobromine a cognitive modulator?
The conceivable action of theobromine alone and associated with caffeine or other cocoa constituents on cognitive modulation is yet underexplored and future studies are needed to shed light on this promising molecule.
Methylxanthines enhance the effects of cocoa flavanols on cardiovascular function: randomized, double-masked controlled studies.
A substantial interaction between cocoa flavanols and methylXanthines exists at the level of absorption, in which the methylxanthines mediate an increased plasma concentration of (-)-epicatechin metabolites that coincides with enhanced vascular effects commonly ascribed to cocoa flavanol intake.
Acute effects of brewed cocoa consumption on attention, motivation to perform cognitive work and feelings of anxiety, energy and fatigue: a randomized, placebo-controlled crossover experiment
Brewed cocoa can acutely reduce errors associated with attention in the absence of changes in either perceived motivation to perform cognitive tasks or feelings of energy and fatigue, and Supplemental caffeine in brewed cocoa can enhance aspects of attention.
The relevance of theobromine for the beneficial effects of cocoa consumption
Theobromine, which is found in higher amounts than caffeine, seems to be behind several effects attributed to cocoa intake, and deserves attention as one of the most attractive molecules in cocoa.
Behavioural effects of compounds co-consumed in dietary forms of caffeinated plants
It is highlighted that more research aimed at understanding the effects of these compounds is needed and, more importantly, the synergistic relationship that they may have with caffeine.
Acute hematological and mood perception effects of bitter orange extract (p‐synephrine) consumed alone and in combination with caffeine: A placebo‐controlled, double‐blind study
Data indicate that consumption of 103‐mg p‐synephrine does not negatively impact acute blood parameters, does not augment the effects of caffeine, or produce stimulant‐like perceptual mood effects.
Mood Components in Cocoa and Chocolate: The Mood Pyramid.
It is concluded that the mood and cognition-enhancing effects of cocoa and chocolate can be ranked from more general activities associated with flavanols and methylxanthines, to more specific activities related to minor constituents such as salsolinol, with on top the orosensory properties of chocolate.


Time for tea: mood, blood pressure and cognitive performance effects of caffeine and theanine administered alone and together
Evidence suggests that theanine is a physiologically and behaviourally active compound and, while it is unclear how its effects might explain perceived differences between tea and coffee, evidence suggests that it may be useful for reducing raised blood pressure.
Reinforcing effects of caffeine and theobromine as found in chocolate
Methylxanthines in amounts found in 50-g chocolate may well contribute to the authors' liking for chocolate, especially to the more acquired taste for dark chocolate.
Methylxanthines are the psycho-pharmacologically active constituents of chocolate
A normal portion of chocolate exhibits psychopharmacological activity, and the identical profile of effects exerted by cocoa powder and its methylxanthine constituents shows this activity to be confined to the combination of caffeine and theobromine.
Discriminative stimulus and subjective effects of theobromine and caffeine in humans
It is suggested that commonly consumed cocoa products contain behaviorally active doses of caffeine and possibly theobromine, as well as other drugs, which are known to produce discriminative effects in humans.
Differential effects of methylxanthines on local cerebral blood flow and glucose utilization in the conscious rat
Theobromine, a substance with less significant adenosine antagonist properties, had minimal effects on local cerebral blood flow and glucose utilization at a dose of 1.6 μmol/kg/min i.v, which may provide supportive evidence for the hypothesis thatAdenosine plays an important role in cerebral bloodflow-metabolism coupling.
Association between ADORA2A and DRD2 Polymorphisms and Caffeine-Induced Anxiety
Ass associations between self-reported anxiogenic effects of caffeine and variation in the genes for A2A (ADORA2A) and DRD2 (DRD2) receptors are examined to provide support for an association between an ADORA 2A polymorphism and self- reported anxiety after a moderate dose of caffeine.

The present results indicate that the CNS action of theobromine may be received through consumption of the Obromine-containing foodstuffs or beverages in the authors' every day life.
Absorption rate of methylxanthines following capsules, cola and chocolate
The results suggest that a usual dietary portion of the cola or chocolate used in this study would produce behaviorally discriminable plasma levels of caffeine in most subjects and of theobromine in at least one subject.
Comparative stimulant and diuretic actions of caffeine and theobromine in man
Caffeine altered self‐estimates of sleep latency and sleep quality in a dose‐dependent fashion and increased overnight urinary sodium excretion and theobromine in equivalent doses had no detectable effect on sleep parameters or on urine composition.
Effects of caffeine on performance and mood depend on the level of caffeine abstinence
Caffeine reliably improved performance on a sustained attention task, and increased rated mental alertness, in moderate caffeine consumers who were tested when caffeine-deprived, consistent with the view that reversal of caffeine withdrawal is a major component of the effects of caffeine on mood and performance.
