5-HTP is a compound formed in the body type of the amino acid tryptophan. It is an originator to the hormone and the melatonin neurotransmitter serotonin 5-HTP supplements have become most loved these days, as it is believed that providing 5-HTP to the body in the form of a pill can boost the serotonin levels in the body, similar to antidepressants that are believed to raise the amount of serotonin present in the brain. Some studies have indicated that 5-HTP might prevent migraines and decrease the regularity and sternness of migraines. Some side effects of 5-HTP are dizziness, nausea, and diarrhea. Sometimes an allergic reaction to the drug may occur.

Acetyl L-Carnitine is a form of L-carnitine, only acetylated. It is a very popular dietary supplement derived from amino acids, methionine and lysine. L-carnitine helps fatty acids to cross the membrane of the mitochondria and become available for usage. ALCAR, which is an alternate name for acetyl L-carnitine, is currently under research for possible treatment of Parkinson’s disease and cerebral ischemia. Neuroprotective benefits have been already attributed to ALCAR, but also assistance in cases of Peyronie’s disease, strokes and in treatment of depression. In food it is very much present in Beef and other red meats, in smaller quantities in mushrooms and carrots. Scientific studies have verified that regular supplements of L-carnitine improve the energy metabolism and can promote the neurotransmitter functions in brains of elderly people.

Caffeine is extracted from coffee and tea during the process of decaffeination. Caffeine Anhydrous can be produced from dimethyl urea and malonic acid. It stimulates the central nervous system, enhancing the focus, concentration, and alertness, and warding off drowsiness. It is a mild diuretic and can also increase the metabolism. It increases the energy level and reduces fatigue. Aside from increasing mental alertness, it also helps in maximizing weight loss training. It stimulates the metabolism that helps the body to burn fat faster and uses the fat as energy. It also provides physical energy and delays the onset of fatigue.

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.

Green Tea Extract- Camellia sinensis, or more commonly the tea plant is a genus of flowering plants which is generally being used to produce tea, including green tea, oolong, black tea, white tea and pu-erh tea, also called Bolay tea. The different oxidation process makes the final difference. Tea plants can grow out into a tree, but are generally pruned to allow for easy hand picking. While camellia sinensis is being cultivated all around the globe in tropical and subtropical regions, this South and Southeast Asian native is most popular when imported from India and China. Medical uses of tea stem from the traditional Chinese medicine, where it was used as a bronchodilator and to treat angina pectoris, coronary artery disease and peripheral vascular diseases. Green tea extract is used as appetite suppressant and thermogenesis increasing agent.

Guarana Extract is the extract of the guarana plant. It contains a significant amount of guaranine, a substance that is similar to caffeine found in coffee beans. It helps stimulate the adrenal glands and increase the production and release of hormones such as epinephrine, norepinephrine (adrenaline), and dopamine. This helps the metabolism of the body that enhances fat loss, and increases energy and endurance. It helps the body burn the fats to be used for energy. It aids in fighting stress, weakness and fatigue. As a stimulant, it also improves mental alertness, clarity, focus, concentration, and memory retention. Guarana also also improves the libido or sex drive in both men and women. Guarana also contains tannins that help prevent diarrhea and soothes the digestive system.

Guggulsterone is a plant sterol found in the resin of the guggul plant, Commiphora mukul. It acts as an antagonist of the farnesoid X receptor, which was earlier believed to result in decreased cholesterol synthesis in the liver.

Hoodia Gordonii is a water retaining plant, also known as a succulent, which grows without leafs. Being native to the south of Africa, it has been in use for an indeterminable amount of time as an appetite suppressant. It is very easily identifiable, because the flowers of this plant have a rotten meat odor. The ingredient of the plant which is responsible for the appetite suppressing effects has been named P57. It is a steroidal glycoside which seems to act directly to the central nervous system’s mechanisms and supposedly raises the content of adenosine triphosphate in brain by at least a half. The effects of P57 in trials were registered as capable to reduce food intake by some fifty per cent on a daily basis.

Medium Chain Triglycerides (MCT) are fatty acids which are shorter in length. They therefore are similar to carbohydrates and get easily digested and absorbed and get used up as energy. It is used as an alternative source of food by patients who are unable to digest normal oils and fats. Medium chain triglycerides are water-soluble and because if their short length get absorbed into the blood stream quickly. From the bloodstream it gets directly transported to the liver. It is an immediate source of energy and only a miniscule percent of it gets converted to body fat. It is naturally found in coconut oil, milk fat and in palm oil. Medium chain triglycerides are available in capsule and in liquid form; this is obtained through the process of lipid fractionation.

Octopamine is a secretion initially discovered in the salivary glands of the Octopus and hence the derivation of the name. it tendso to act as a neurotransmitter, transmitting messages from the neurons to the brain and vice versa. Octopamine has been found to have a tendency to release fat deposits from cells, thus aiding in the loss of weight. It is therefore being used as a slimming agent by most people, even though there is no concrete evidence that it does assist in weight loss, for sure. Octopamine is also believed to increase blood pressure levels when it is in combination with other weight loss stimulating supplements. Although not much is known about Octopamine, a deeper study is being conducted into its uses and effects.

Synephrine HCL- Designed primarily to encourage fat loss. This is achieved by stimulating the beta-3 receptors. Doing so increases the metabolic rate leading to fat loss. Synephrine is a stimulant similar to caffeine and ephedrine and it is believed to provide an energy boost, suppress appetite and increase metabolism. The combination of all leads to burning more calories. Studies have stated that synephrine stimulates fat metabolism without the usual negative cardiovascular side effects. The effectiveness of synephrine is increased by combining it with HCL. This allows for increased absorption and more solubility in water. However regardless of the increasing popularity of synephrine HCL, there are still some debates over its over all effects and it being used as an alternative to ephedrine, a substance made illegal by many countries due to the side effects including heart disease.

Vinpocetine, a memory enhancer. Vinpocetine makes cerebral microcirculation (blood flow) easier, increases brain cell ATP production, and increases useability of glucose and oxygen.

Yohimbine HCL, sometimes called yohimbine hydrochloride, yohimbe, or yohimbe bark, is an herbal supplement which serves as a stimulant and possible aphrodisiac for users. Yohimbine has also been shown to be successful in treating erectile dysfunction and impotence in men. It may serve to boost the sex drive of those who take it for aphrodisiac purposes. Some people are recommended to take yohimbine to combat their lower sex drives caused by antidepressants. Yohimbine has also been shown to help blood pressure levels and assist in weight loss. For these reasons, yohimbine is a popular supplement amongst athletes as well as many others wishing to improve their health.
