Unlike most other psychoactive substances, caffeine remains largely unregulated and legal in nearly all parts of the world. Caffeine is the world's most widely consumed psychoactive drug. In 2020, almost 10 million tonnes of coffee beans were consumed globally. Caffeine-containing drinks, such as coffee, tea, and cola, are consumed globally in high volumes. ![]() To make these drinks, caffeine is extracted by steeping the plant product in water, a process called infusion. People may drink beverages containing caffeine to relieve or prevent drowsiness and to improve cognitive performance. The best-known source of caffeine is the coffee bean, the seed of the Coffea plant. It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, and helps to protect them against herbivores and from competition by preventing the germination of nearby seeds, as well as encouraging consumption by select animals such as honey bees. Ĭaffeine 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). Caffeine also increases cyclic AMP levels through nonselective inhibition of phosphodiesterase. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine acts by blocking binding of adenosine to the adenosine A 1 receptor, which enhances release of the neurotransmitter acetylcholine. It is mainly used recreationally, as a eugeroic ( wakefulness promoter) or as a mild cognitive enhancer to increase alertness and attentional performance. Looking for an exciting new tea to try-with or without theine? We've got you covered.Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. I'll try my best to do better next theine.) Ultimately, it doesn't really matter what you call it-just don't call it late for tea. However, there are some subtle differences between the "experiences" that one associates with caffeine from coffee and caffeine from tea, which is probably why the term theine has continued to stick around among tea enthusiasts. The term "theine" is simply another name for caffeine that is found in tea. So to recap, theine and caffeine are one and the same. It counteracts some of the stimulating effects of caffeine with a sense of relaxation (importantly, without any appreciable reduction in "alertness") Teas contain the unique amino acid, L-theanine.This difference in the way that tea and coffee affect the body is due to the fact that tea also contains other compounds, like catechins and flavonoids, which interact with caffeine to provide a unique set of benefits. In other words (literally) "theine" gives you a different kind of buzz. When you drink tea, the caffeine is metabolized more slowly, which results in a more gradual and longer-lasting release of energy. On top of that, the way that caffeine is metabolized in the body is different when it comes from tea as opposed to coffee.On average, a cup of tea has, at most, about half the caffeine of a cup of coffee usually less than that. ![]() For one thing, there's much less caffeine in a cup of tea than in a cup of coffee.Now, how is that possible? They're literally the same molecule. ![]() While the "theine" in tea and the caffeine in coffee are-in all scientific terms-identical, you could say that theine and caffeine in tea and coffee respectively feel a little bit different when they’re consumed. Other than that, as long as you're not confusing theine with theanine, you're fine. Referring to theine in coffee doesn't make sense (unless you poured a cup of tea into your coffee). It's still considered perfectly acceptable to refer to caffeine as theine specifically when it's in tea-just not the other way around. Some parts of the tea community still refer to the caffeine in tea as theine, and they're not incorrect. Then, some Dutch and German chemists found that they were exactly the same thing, so the word "theine" was mostly dropped in favor of the word “caffeine.” For about a decade, it was thought to be a different substance than caffeine. See, theine was first discovered in tea by French chemists in the early 1800s. In fact, in some places, the two terms are used interchangeably. That's because theine is simply another name for caffeine-in tea. What's more, it can even help you be more productive, more creative, and keep you awake when you need it most. Theine also has numerous health benefits, such as promoting weight loss, reducing inflammation, and improving heart health. It's the compound responsible for many of the effects of the true teas-black, green, and white teas-that help to improve energy, focus, and mental alertness. Theine is a naturally-occurring stimulant found in tea.
