Caffeine is a methylated xenthine discovered in 1819 by Friedrich Ferdinand Runge, a German chemist. Sources of Caffeine include beans, fruit and leaves of some plants. Caffeine available for human consumption is most commonly extracted from the coffee plant cherries and tea bush leaves, as well as foods and drinks that contain products derived from the kola nut. Caffeine can temporarily reduce the sensation of being tired; however, this does not mean that it eliminates the need for sleep. Generally, twenty five to fifty milligrams of caffeine is enough for most consumers to report an increase in alertness and arousal. Caffeine should be not be consumed by those with fecal incontinence as it relaxes the internal anal sphincter muscles.

Synephrine, a semi-selective sympathomimetic, is used to stimulate the adrenaline system. Also known as ‘zhi shi’, green orange or bitter orange; it is a chief, active constituent found in the fruit belonging to the plant, Citrus aurantium. Synephrine is not only similar to ephedra in its chemical composition but also serves the same benefits as caffeine or ephedrine. However, it mildly stimulates the fat metabolism without causing any of the side effects associated with ephedra based products. The best advantage of using Synephrine is that it increases the metabolic rate without affecting the hemodynamics. Thus, it is comparatively much safer than ephedra. Since Synephrine promotes weight loss and supports thermogenesis, Synephrine supplements are an ideal solution for dieters and weight watchers. The total intake should be between 2 to 10 mg. per day.

Synthetic Guggulsterones is naturally found in the resin of the guggul plant, it is a plant sterol and the Latin name of the plant is Commiphora mukul. It is believed that in humans, an extract of the guggul plant functions as a farnesoid X receptor inhibitor, theoretically attributing to a diminished synthesis of cholesterol in the liver. It is a very popular nutritional supplement and exists in several synthetic variants which are popular with the body building communities. The most popular application is the one as a weight loss agent, but it has been observed that Synthetic Guggulsterones may also stimulate thyroid function directly. While there is a debate if synthetic or natural guggulsterones are to be preferred, the availability and price of Synthetic Guggulsterones is currently prevailing.

Yohimbe is an alkaloid and the active ingredient of a medicinal herb also known as Pausinystalia yohimbe, formerly named Corynanthe yohimbe. It is noted as a stimulant drug and also as an aphrodisiac. While the medicinal community has conducted numerous studies of yohimbe in conjunction with sexual dysfunctions, in veterinary medicine, yohimbine is employed as the antidode to anesthesia stemming from the drug xylazine in large and small animals. In recent times, yohimbine has been found to instigate fat loss in athletes when taken orally. There are also some formulations available, for a significant price, where yohimbine can be directly applied transdermally to adipose tissue, leading to a local reduction. This application is still in experimentation and should not be used without professional assistance.
