Remember that caffeine is found in quite a few sources including: tea, green tea, coffee, energy drinks, cola and chocolate Should I avoid energy drinks because of their caffeine content? The effects of decaf coffee on liver function are not as well studied as those of regular coffee. However, one large observational study linked decaf coffee with reduced liver enzyme levels, which suggests a protective effect ( 22).

Some studies looking at tea and coffee intake (not caffeine specifically) have shown that drinking one to three cups of coffee a day may be linked to a lower risk of certain diseases. These include type 2 diabetesand Parkinson’s disease. But more research is needed before doctors can be sure if caffeine lowers your risk of disease. How much caffeine should you have in a day?

Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, [18] and helps to protect them against herbivores and from competition by preventing the germination of nearby seeds, [19] as well as encouraging consumption by select animals such as honey bees. [20] The best-known source of caffeine is the coffee bean, the seed of the Coffea plant. People may drink beverages containing caffeine to relieve or prevent drowsiness and to improve cognitive performance. To make these drinks, caffeine is extracted by steeping the plant product in water, a process called infusion. Caffeine-containing drinks, such as coffee, tea, and cola, are consumed globally in high volumes. In 2020, almost 10 million tonnes of coffee beans were consumed globally. [21] Caffeine is the world's most widely consumed psychoactive drug. [22] [23] Unlike most other psychoactive substances, caffeine remains largely unregulated and legal in nearly all parts of the world. Caffeine is also an outlier as its use is seen as socially acceptable in most cultures and even encouraged in others. Some people use caffeine-containing beverages such as coffee or tea to try to treat their asthma. [45] Evidence to support this practice is poor. [45] It appears that caffeine in low doses improves airway function in people with asthma, increasing forced expiratory volume (FEV1) by 5% to 18% for up to four hours. [46]

Mixing caffeine with other drugs

In 1827, M. Oudry isolated "théine" from tea, [264] but in 1838 it was proved by Mulder [265] and by Carl Jobst [266] that theine was actually the same as caffeine. Garfield, Leanna.

Some textbooks state that caffeine is a mild euphoriant, [104] [105] [106] while others state that it is not a euphoriant. [107] [108]

In healthy children, moderate caffeine intake under 400mg produces effects that are "modest and typically innocuous". [74] [75] As early as six months old, infants can metabolize caffeine at the same rate as that of adults. [76] Higher doses of caffeine (>400mg) can cause physiological, psychological and behavioral harm, particularly for children with psychiatric or cardiac conditions. [74] There is no evidence that coffee stunts a child's growth. [77] The American Academy of Pediatrics recommends that caffeine consumption is not appropriate for children and adolescents and should be avoided. [78] This recommendation is based on a clinical report released by American Academy of Pediatrics in 2011 with a review of 45 publications from 1994 to 2011 and includes inputs from various stakeholders (Pediatricians, Committee on nutrition, Canadian Pediatric Society, Centers for Disease Control & Prevention, Food and Drug Administration, Sports Medicine & Fitness committee, National Federations of High School Associations). [78] For children age 12 and under, Health Canada recommends a maximum daily caffeine intake of no more than 2.5 milligrams per kilogram of body weight. Based on average body weights of children, this translates to the following age-based intake limits: [72] Age range Caffeine's biological half-life– the time required for the body to eliminate one-half of a dose– varies widely among individuals according to factors such as pregnancy, other drugs, liver enzyme function level (needed for caffeine metabolism) and age. In healthy adults, caffeine's half-life is between 3 and 7hours. [8] The half-life is decreased by 30-50% in adult male smokers, approximately doubled in women taking oral contraceptives, and prolonged in the last trimester of pregnancy. [126] In newborns the half-life can be 80hours or more, dropping very rapidly with age, possibly to less than the adult value by age 6 months. [126] The antidepressant fluvoxamine (Luvox) reduces the clearance of caffeine by more than 90%, and increases its elimination half-life more than tenfold; from 4.9hours to 56hours. [187] For the general population of healthy adults, Health Canada advises a daily intake of no more than 400mg. [72] This limit was found to be safe by a 2017 systematic review on caffeine toxicology. [73] Children Studies have shown that drinking caffeine before exercise can lead to a small improvement in performance across different types of training. This includes endurance, high-intensity and power sports.a b c d e f g h i j k l m n o p "Caffeine". DrugBank. University of Alberta. 16 September 2013. Archived from the original on 4 May 2015 .
