Paraxanthine, also known as 1,7-dimethylxanthine, is an isomer of theophylline and theobromine, two well-known stimulants found in coffee, tea, and chocolate mainly in the form of caffeine.

1,7-dimethylxanthine is a dimethylxanthine having the two methyl groups located at positions 1 and 7. It is a metabolite of caffeine and theobromine in animals. It has a role as a central nervous system stimulant, a human xenobiotic metabolite, a human blood serum metabolite and a …

Paraxanthine (1,7-dimethylxanthine) is a metabolite of caffeine that can be found naturally in small amounts in some foods including green coffee beans, cotyledonary leaves of Coffea arabica, Theobroma cacao fruits, roasted coffee beans, citrus flowers and Sicilian orange flower honey (Waller et al., 1983; Kappeler and Baumann, 1985; Kretschmar ...

Chemically, paraxanthine is 1,7-dimethylxanthine with two methyl groups located at positions 1 and 7. Paraxanthine accounts for about 80 percent of caffeine ingested, with smaller percentages of caffeine being metabolized to theobromine and theophylline. 1 It’s been shown that 11 percent of caffeine ends up as theobromine and 4 percent as ...

Paraxanthine (1,7-dimethylxanthine) is a natural dietary ingredient and the main metabolite of caffeine in humans [1]. Supplementation with caffeine in humans increases various aspects of athletic performance, including muscular strength, muscular endurance, and …

Paraxanthine, or 1,7-dimethylxanthine, is a dimethyl derivative of xanthine, structurally related to caffeine. Like caffeine, paraxanthine is a psychoactive central nervous system (CNS) stimulant. It possesses a potency roughly equal to that of caffeine and is likely involved in the mediation of the effects of caffeine itself.
