What You Should Know
Caffeine is an odorless, slightly bitter organic compound found mostly in beverages such as coffee or tea and in chocolate. It is the most widely used “mind-altering drug” in the world, though it is considered safe and is mostly unregulated. Caffeine acts as a mild stimulant on the nervous system, aiding in alertness. Caffeine is also included in many weight loss supplements due to its reputation of acting as an appetite suppressant and in stimulating thermogenesis. A number of over the counter pain relievers, headache remedies and antihistamines contain caffeine.
Caffeine is an ingredient.
Caffeine is a compound that is produced naturally in the many plants and nuts. Although it is widely available without a prescription, caffeine is defined as a drug because it stimulates the central nervous system, causing increased alertness and giving most people a temporary energy and mood boost. Caffeine is known to stimulate thermogenesis, one of the ways the body generates heat and energy from digested food. Caffeine may also act as an appetite suppressant and as a diuretic.
There are many sources of caffeine available on the market today. In addition to being found in coffee, tea, energy waters, cocoa and carbonated beverages, caffeine is also found in a variety of chocolates. It is also present in a number of weight loss supplements in the form of kola nut seeds, bissey nut, guarana, citrus aurantlum extract and yerba mate. It is important to know what form of caffeine is in any diet product you purchase as some do come with safety warnings. It is also important to avoid mixing too many forms of caffeine in one formula as this can lead to restlessness, sleeplessness and heart irregularities.
