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.

Evodiamine- Tetradii Fructus, the fruit of the evodia plant, also known as Tetradium rutaecarpa, contains an active element that has recently been identified as evodiamine. This chemical compound is believed to be somewhat similar to capsaicin, the active compound found in the chili peppers. Some studies suggested that this vanilloid receptor agonist may interact with thermogenin, otherwise known as the uncoupling protein 1, UCP1, which is able to generate heat by a mechanism called thermogenesis. Tetradium rutaecarpa has been traditionally used in Chinese medicine for weight loss purposes and current studies seem to verify this information. Evodiamine has been embraced as a dietary supplement directed at weight loss, predominantly by the body building circles. This supplement is deemed to have energy burning and fat reducing, as well as diuretic properties.

Fursultiamine is a thiamine derivative which is similar in design like sulbutiamine. Thiamine is among the most vital B-vitamins for carbohydrate and fat metabolism. Fursultiamine, a vitamin B1 derivative, is known to decrease or end the accelerated heartbeat that usually accompanies use of stimulants like ephedrine. It significantly increases cellular ATP production in muscles and the brain, and also improves exercise performance and reduces muscle fatigue. In rabbit experimental osteoarthritis, fursultiamine increased chondroprotective effects of glucosamine hydrochloride and chondroitin sulfate. In a study, it alleviated shortness of breath and chest pain caused by a beriberi heart condition, which is known as thiamine deficiency.

Gelatin constitutes the shells of pharmaceutical capsules in order to make them easier to swallow.

It may also prevent other diseases such as Parkinson’s disease, cataracts and cancer, particularly ovarian cancer. It helps boost the production of energy. It also helps in the production of T3, a thyroid hormone, which boosts the metabolism which in turn, helps in weight loss.

Raspberry Ketones- Red raspberries contain a phenolic compound, which is the main aroma in red raspberries. This raspberry ketone is being used in cosmetics and perfume industries, but also as a food additive. While the use as a weight loss agent has not yet been clinically tested on human subjects, preliminary research in lab mice has shown that raspberry ketones in high doses show a norepinephrine induced lipolysis. This leads to the effect that even a diet high on fats did not result in higher body weight. This fact has immediately led to the embrace of raspberry ketones by the weight loss and body building communities, despite the fact that raspberry fruits would be much healthier, containing ellagic acid, catechins, salicylic acid, and various other polyphenols, besides large quantities of Vitamin C.
