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.

Pantothenic Acid or vitamin B5 is a water soluble vitamin that may be found in various food sources such as fish, meat, broccoli, and egg yolk. It forms part of the coenzyme A (CoA) that is important in converting the food we ingest into energy. It stimulates the production and transportation of energy from fats. It also helps in maintaining a healthy digestive tract and prevents the liver from becoming fatty. Pantothenic acid is also known for preventing stress.

Some other compounds have been added to the Vitamin B group at some time, but were later dropped, like adenine, orotic acid or adenosine monophosphate, where later research found that they are either synthesized by the human body or simply no Vitamins. Vitamin B complex supports the metabolism rate, maintains muscle tone and skin, raises functions of the nervous system and the immune system, promotes red blood cells and cell growth and division and much more.

Vitamin B12 is a water soluble vitamin and is one of the 8 B vitamins. It has the chemical formula C63H88CoN14O14P. In the absence of Vitamin B12, the brain and the nervous system will not be able to function properly. It also plays a key role in the formation of blood. Vitamin B12 was discovered from its relation to the ailment pernicious anemia. Plants and animals are not capable of synthesizing VitaminB12; the enzymes required for this purpose are found only in bacteria.

Vitamin B2 , an easily absorbed micronutrient, is also known by the name of Riboflavin. It plays a key role in maintaining the health of animals as well as humans.

Vitamin B6’s role as a coenzyme involved in the metabolism of carbohydrates, fats, and proteins is what makes it important for dieters.
