Chromium is a natural trace mineral in human nutrition and is needed for proper metabolism of sugar in humans. It is vital for metabolism of fats and carbohydrates. It helps move blood sugar from the bloodstream into cells to be utilized as energy and turn fats, carbohydrates, and proteins into energy. Chromium helps stimulate fatty acid and cholesterol synthesis, which are needed for brain function and other body processes. It activates numerous enzymes that are required to drive many chemical reactions essential to life. Chromium supplements also improve glucose tolerance in people with Turner's syndrome, a disease associated with glucose intolerance. It is also vital for insulin metabolism. It regulates hunger and decreases cravings.

Damiana is a shrub belonging to the family of Turneraceae. Even though it is a small shrub, it produces aromatic, small flowers. It is generally found in the regions of South America, Caribbean, Mexico and Central America. It is also a fruit bearing shrub. The flowers generally blossom in late summer on the damiana shrub. Then the fruits follow. The fruit it bears is quite similar in taste to figs. It emits a smell which is quite similar to the odor of chamomile. The oils present in the shrub are reason behind this odor. It is said to have aphrodisiac properties. Natives of south and Central America use the leaves to make tea. In Mexico, the tea made with damiana leaves is generally drunk with sugar so as to increase the love making ability.

Garcinia Cambogia- Gambooge, a subtropical version of the Garcinia genus and native to Indonesia, is the local name for garcinia cambogia. It bears a pumpkin like yellow coloured fruit, which extract, together with the rind, is in India a curry condiment. Extracts are also being used in several herbal appetite suppressants, but also in some energy providing products and supplements. In the body building community, besides the weight loss properties of garcinia cambogia, the main component, hydroxycitric acid, or HCA, seems to increase the levels of lipolysis in athletes. HCA may even prove to be more effective in combined use with carnitine and pyruvate. In India, garcinia cambogia was traditionally used to treat edema, constipation, irregular menstruation and against intestinal parasites. Further uses include combating rheumatism and bowel related troubles.

Glucomannan, also called propolene, not to be confused with propylene, is a polysaccharide and mainly a straight chain polymer. It is widely used as a food additive, E number E425, with thickening and emulsifying characteristics. Glucomannan comprises almost half of the corm of the amorphophallus konjac plant, the so called “devil’s tongue” plant, native to warmer subtropical to tropical eastern Asia. Some studies have shown that this dietary fiber may hold multiple health benefits. It has been and currently is in clinical trials for treatment of constipation, obesity, cholesterol and type 2 diabetes. For weight control purposes, it has been observed that glucomannan promotes satiety when ingested, significantly reducing food cravings. It was also observed that when used with chitosan, glucomannan seemed to decrease serum cholesterol.

Glucosamine is derived from chitin found in shells of crabs, shrimp, and oysters. There is sufficient scientific evidence to prove that glucosamine sulfate is both safe and effective for treating mild to moderate osteoarthritis of the knee. Research also indicates analgesic and disease-modifying effects of glucosamine sulfate. However, this does not imply that side effects of glucosamine sulfate do not exist. Short term use of glucosamine sulfate may lead to minor side effects such as insomnia, headache, drowsiness, heartburn, constipation, vomiting, and diarrhea and in rare cases, increase in blood pressure and heart rate and palpitations. People with bleeding disorders should not take glucosamine supplements without consulting their physician. These supplements should also be avoided by those allergic to shellfish, which happens to be the primary source of glucosamine.

Guarana- The active constituent of guarana is caffeine, which means that it should not be used alongside ephedrine as either a dietary aid or in order to stimulate performance. The American Food and Drug Administration has not tested its effectiveness or its purity as they do not class it as a drug. Guarana has many other names including Brazilian cocoa and may be a constituent of non alcoholic drinks imported from South America. Because of possible adverse reactions it is not recommended for anyone with a heart condition or who has kidney disease, high blood pressure or who suffers from anxiety.

Gymnema Sylvestre is an herb that has shown to reduce blood sugar and is used by some to reduce sugar cravings as it seemingly reduces the sugar taste when placed in the mouth.
