In 1895, German chemist Hermann Emil Fischer (1852–1919) first synthesized caffeine from its chemical components (i.e. a " total synthesis"), and two years later, he also derived the structural formula of the compound. [267] This was part of the work for which Fischer was awarded the Nobel Prize in 1902. [268] Historic regulations Chen LW, Wu Y, Neelakantan N, Chong MF, Pan A, van Dam RM (May 2016).

Xocolatl was introduced to Europe by the Spaniards, and became a popular beverage by 1700. The Spaniards also introduced the cacao tree into the West Indies [252] and the Philippines.

The UK Food Standards Agency has recommended that pregnant women should limit their caffeine intake, out of prudence, to less than 200mg of caffeine a day– the equivalent of two cups of instant coffee, or one and a half to two cups of fresh coffee. [80] The American Congress of Obstetricians and Gynecologists (ACOG) concluded in 2010 that caffeine consumption is safe up to 200mg per day in pregnant women. [29] For women who breastfeed, are pregnant, or may become pregnant, Health Canada recommends a maximum daily caffeine intake of no more than 300mg, or a little over two 8oz (237mL) cups of coffee. [72] A 2017 systematic review on caffeine toxicology found evidence supporting that caffeine consumption up to 300mg/day for pregnant women is generally not associated with adverse reproductive or developmental effect.

Consumption of caffeine after abdominal surgery shortens the time to recovery of normal bowel function and shortens length of hospital stay. [48]

So, you’ll want to zero in on the reason you’re buying patches, says Dr. Camp. “For example, if you are concerned about puffiness, you may be looking for a product that you can use in the morning before starting your day. In that case, look for ingredients like caffeine or green tea.” Caffeine is also a common ingredient of soft drinks, such as cola, originally prepared from kola nuts. Soft drinks typically contain 0 to 55 milligrams of caffeine per 12 ounce (350mL) serving. [232] By contrast, energy drinks, such as Red Bull, can start at 80 milligrams of caffeine per serving. The caffeine in these drinks either originates from the ingredients used or is an additive derived from the product of decaffeination or from chemical synthesis. Guarana, a prime ingredient of energy drinks, contains large amounts of caffeine with small amounts of theobromine and theophylline in a naturally occurring slow-release excipient. [233] Other beverages Trimethyluric acid is a minor caffeine metabolite. [8] 7-Methylxanthine is also a metabolite of caffeine. [189] [190] Each of the above metabolites is further metabolized and then excreted in the urine. Caffeine can accumulate in individuals with severe liver disease, increasing its half-life. [191] Some analog substances have been created which mimic caffeine's properties with either function or structure or both. Of the latter group are the xanthines DMPX [210] and 8-chlorotheophylline, which is an ingredient in dramamine. Members of a class of nitrogen substituted xanthines are often proposed as potential alternatives to caffeine. [211] [ unreliable source?] Many other xanthine analogues constituting the adenosine receptor antagonist class have also been elucidated. [212] Amphetamines increase dopamine/norepinephrine release and inhibit their reuptake, leading to central nervous system (CNS) stimulationCaffeine also causes the release of dopamine in the dorsal striatum and nucleus accumbens core (a substructure within the ventral striatum), but not the nucleus accumbens shell, by antagonizing A 1 receptors in the axon terminal of dopamine neurons and A 1– A 2A heterodimers (a receptor complex composed of 1 adenosine A 1 receptor and 1 adenosine A 2A receptor) in the axon terminal of glutamate neurons. [169] [164] During chronic caffeine use, caffeine-induced dopamine release within the nucleus accumbens core is markedly reduced due to drug tolerance. [169] [164] Enzyme targets
