Guaranine
El término Guaranine figura en la edición en idioma inglés de Wikipedia. Allí se dice al respecto lo siguiente:

Caffeine is a bitter, white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants, as well as enhancing the reward memory of pollinators. It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. Other sources include yerba maté, guarana berries, guayusa, and the yaupon holly.
In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. Studies have shown that caffeine potentially induces chromosomal aberrations, and shows both teratogenic and mutagenic properties. It is the world's most widely consumed psychoactive drug, but unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world. Beverages containing caffeine, such as coffee, tea, soft drinks, and energy drinks, enjoy great popularity. In North America, 90% of adults consume caffeine daily.
Part of the reason caffeine is classified by the Food and Drug Administration as GRAS (generally recognized as safe) is that toxic doses (over 10 grams for an average adult) are much higher than typically used doses (less than 500 milligrams). Ordinary consumption can have low health risks, even when carried on for years – there may be a modest protective effect against some diseases, including Parkinson's disease and certain types of cancer. Some people experience sleep disruption if they consume caffeine, especially during the evening hours, but others show little disturbance and the effect of caffeine on sleep is highly variable.
Evidence of a risk to pregnancy is equivocal, but some authorities have concluded that prudent advice is for pregnant women to limit consumption to the equivalent of two cups of coffee per day or less. The American Congress of Obstetricians and Gynecologists (ACOG) concluded in 2010 that caffeine consumption is safe up to 200 mg per day in pregnant women. Caffeine has pressor and mild diuretic effects when administered to people who are not used to it, but regular users develop a tolerance to this effect, and studies have generally failed to support the common notion that ordinary consumption contributes significantly to dehydration. With heavy use, tolerance develops rapidly to autonomic effects such as elevated heart rate and muscle twitching, but not to the cognitive or arousal effects of caffeine. The degree to which caffeine can produce clinically significant dependency and caffeine addiction remains a subject of controversy in the medical literature.[citation needed]
