Product Information

Pure anhydrous caffeine is a bitter-tasting, white, odorless powder with a melting point of 235–238°C. [10] [11] Caffeine is moderately soluble in water at room temperature (2g/100 mL), but very soluble in boiling water (66g/100 mL). [193] It is also moderately soluble in ethanol (1.5g/100 mL). [193] It is weakly basic (pK a of conjugate acid = ~0.6) requiring strong acid to protonate it. [194] Caffeine does not contain any stereogenic centers [195] and hence is classified as an achiral molecule. [196] Tablets offer several advantages over coffee, tea, and other caffeinated beverages, including convenience, known dosage, and avoidance of concomitant intake of sugar, acids, and fluids. A use of caffeine in this form is said to improve mental alertness. [238] These tablets are commonly used by students studying for their exams and by people who work or drive for long hours.

Drinking 2–4 cups of coffee per day may reduce liver cancer risk by up to 64% and colorectal cancer risk by up to 38% ( 41, 42, 43, 44, 45).

What about when you actually drink it? “There’s a chance that the use of any supplement will carry a placebo effect,” says Dr Mike T Nelson, a researcher and performance specialist who recently co-wrote the International Society of Sports Nutrition’s position on coffee. “Many researchers use randomised, double-blinded, placebo-controlled trials to try to ferret that out. And if you look at some of the higher-dose caffeine studies and when they have been compared with a placebo, we still see a performance-enhancing effect of caffeine.” In addition, there have been several reports of rhabdomyolysis related to excessive caffeine intake, although this is relatively rare ( 26, 27, 28, 29).By default the app starts enabled, and works every 59 seconds. There are some command line switches you can use to alter this behaviour: Caffeine overdose can result in a state of central nervous system overstimulation known as caffeine intoxication, a clinically significant temporary condition that develops during, or shortly after, the consumption of caffeine. [140] This syndrome typically occurs only after ingestion of large amounts of caffeine, well over the amounts found in typical caffeinated beverages and caffeine tablets (e.g., more than 400–500mg at a time). According to the DSM-5, caffeine intoxication may be diagnosed if five (or more) of the following symptoms develop after recent consumption of caffeine: restlessness, nervousness, excitement, insomnia, flushed face, diuresis, gastrointestinal disturbance, muscle twitching, rambling flow of thought and speech, tachycardia or cardiac arrhythmia, periods of inexhaustibility, and psychomotor agitation. [141] Caffeine, noun (feminine). Crystallizable substance discovered in coffee in 1821 by Mr. Robiquet. During the same period– while they were searching for quinine in coffee because coffee is considered by several doctors to be a medicine that reduces fevers and because coffee belongs to the same family as the cinchona [quinine] tree– on their part, Messrs. Pelletier and Caventou obtained caffeine; but because their research had a different goal and because their research had not been finished, they left priority on this subject to Mr. Robiquet. We do not know why Mr. Robiquet has not published the analysis of coffee which he read to the Pharmacy Society. Its publication would have allowed us to make caffeine better known and give us accurate ideas of coffee's composition... However, it has been shown to raise blood pressure in several studies due to its stimulatory effect on the nervous system ( 33, 34, 35, 36).

Most research looking at the compound’s effects on urinary frequency has focused on older people and those with overactive bladders or incontinence ( 43, 44, 45). It may also increase blood adrenaline levels and increase brain activity of the neurotransmitters dopamine and norepinephrine ( 3). Wikoff D, et al.

This is the same as: On the other hand, some studies suggest that caffeinated beverages may worsen gastroesophageal reflux disease (GERD) in some people. This seems to be especially true of coffee ( 23, 24, 25).
