Bioperine- Basically a pure and safe nutritional supplement of piperine, Bioperine can have several positive effects on our body. It contains about ninety five percent of piperine that is known to enhance the bioavailability of nutrients. As a result, bioperine intake helps in rapid absorption of nutrients from the gastrointestinal tract. Owing to its affinity for the fatty tissue, it even interacts with the lipid component of the intestinal cell membrane thereby allowing further nutrient permeability. It is quite popular due to its ability to enhance thermogenesis. This is how it works - the piperine present in bioperine stimulates the release of catecbolamines that trigger thermogenesis in the GI tract thus, making more energy available for digestion. It can be combined with other nutrients too to improve the health of human beings as well as animals.

Evodiamine, an alkaloid extract from the Evodiae Fructus plant is known as Evodiamine. It has been referred to as a “hot nature” herb in Chinese literature and medicine. Based on animal studies, Evodiamine increases the natural fat burning rate and stimulates vanilloids for reduction of fat intake. It increases body temperature, influences the adrenal glands to secrete catecholamines and also affects the metabolism of certain drugs. Since it acts like a thermogenic and increases the overall temperature, more fat and calories are burnt due to its intake. This alkaloidal compound has anti obesity effects due to UCP1 (uncoupling protein 1) thermogenesis. In part, evodiamine can prevent diet induced obesity from developing further. It is available in the form of supplement or through Evodiae Fructus plant.

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 is not only a dietary supplement but also an energy booster as well as it has a high concentration of caffeine.

Hoodia Gordonii, which although popular, has no published randomized controlled trials in humans to show hoodia is safe or effective in pill form. One study published in the September 2004 issue of Brain Research found that injections of p57 (The Active ingredient in Raw, Fresh Cut Hoodia, not dried) into the appetite center of rat brains resulted in altered levels of ATP, an energy molecule that may affect hunger. The animals receiving the P57 injections also ate less than rats that received placebo injections. However, this was an animal study and INJECTIONS IN THE BRAIN are very different from oral consumption, so it cannot be used to show that oral hoodia can suppress appetite in humans. Hoodia Gordonii is a succulent (a cactus of the aloe family) found in the Kalahari desert of South Africa. Most Hoodia Gordonii products contain very little, if any of the active ingredient needed to suppress hunger. Real Hoodia is very rare and is even an endangered plant. Most importantly, Hoodia has only demonstrated any effect in fresh, raw pieces of the plant. The effectiveness of powdered Hoodia has yet to be shown and may actually increase hunger. It's main use is as a cheap alternative to the more expensive weight loss herbs, which are the only alternative left after the banning of ephedra. Most supplement manufacturers can not use the more expensive weight loss herbs because it will result in a product that would be too expensive to compete with other more popular inexpensive diet supplements.
