<Li> Theobromine (12%): Dilates blood vessels and increases urine volume . Theobromine is also the principal alkaloid in the cocoa bean (chocolate). </Li> <Li> Theophylline (4%): Relaxes smooth muscles of the bronchi, and is used to treat asthma . The therapeutic dose of theophylline, however, is many times greater than the levels attained from caffeine metabolism . </Li> <P> 1, 3, 7 - Trimethyluric acid is a minor caffeine metabolite . Each of these metabolites is further metabolized and then excreted in the urine . Caffeine can accumulate in individuals with severe liver disease, increasing its half - life . </P> <P> A 2011 review found that increased caffeine intake was associated with a variation in two genes that increase the rate of caffeine catabolism . Subjects who had this mutation on both chromosomes consumed 40 mg more caffeine per day than others . This is presumably due to the need for a higher intake to achieve a comparable desired effect, not that the gene led to a disposition for greater incentive of habituation . </P>
