Caffeine is the most widely used legal stimulant of the central nervous system and is also used in Plexilean, with characteristics that have been described as restoration of alertness and removing from drowsiness. Coffee, Tea, many soft drinks and energy drinks as well as nutrition supplements have this ingredient, which is a psychoactive substance, a xanthine alkaloid that can act as a adenosine receptor antagonist, as well as a phosphodiesterase inhibitor. Although regular use of caffeine seems to have nootropic effects, enhancing cognitive abilities, it also is known to provide long term effects on the nervous and cardiovascular system, like in one study it was proven that people with normal to low blood pressure have the possibility of developing a heart disease significantly reduced, as well as the chance of getting the Parkinson’s disease.

Chromium Picolinate is a combination of chromium and picolinate acid. Combined with exercise, it is commonly used to lose weight through reducing appetite, increasing metabolism rate and melting fats. This, however, has not been proved clinically. It is also believed to increase energy, life span, prevent acne and improve a person’s mood. Being considered a natural alternative to steroids, it is recommended to athletes. Chromium is found in fish, poultry, whole-grains, cheese and meat. It helps in the proper working of cells by improving the efficiency of insulin. Picolinate acid helps in the proper absorption of chromium. A combination of chromium picolinate and other supplements may be risky, hence professional advice should be sought before using it. Pregnant or nursing women should also be careful.

Folic Acid produces healthy red blood cells and prevents anemia in both children and adults. It is especially important in pregnancy and infancy and is also believed to help in the prevention of cancer, stroke and heart disease.

Green Tea Extract increases energy expenditure and affects fat oxidation, which therefore promotes weight loss by increasing the body's metabolism.

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.

Niacin is an essential B vitamin, in cellular energy used for the promotion of healthy cardiovascular function, nervous system function, and immune function. Niacin nutritionally manages cholesterol levels already within the normal range. Also known as vitamin B3, niacin is one of a complex of B vitamins that are essential for good health. Niacin is so-called nicotinic acid, known also as nicotinamide. It helps regulate blood sugar and also works at cellular level protecting the skin and enhances the digestive system. And being an originator of the amino acid tryptophan, it can be made by tryptophan in the body. It’s also a coenzyme playing an important role in body metabolism. Supplements of vitamin B3 are also known to reduce levels of bad cholesterol and increase good cholesterol in the blood.

Pantothenic Acid is thought to reduce lactic acid accumulation in athletes, may improve oxygen utilization efficiency, and is believed to improve the body's ability to heal and possibly help in reducing acne

Vitamin B1, or rather the Vitamin B complex, is a group of vitamins that are all soluble in water and very often coexist in food sources. While every single Vitamin from the B complex group has a name, they are very often referred to by the number added to the Vitamin B group name, like Vitamin B1, which is thiamine, or Vitamin B2, which is riboflavin. 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 required for the normal functioning and development of the nervous system, blood cells and brain. It’s a water soluble vitamin which is used to elevate mood, improve energy levels and concentration, to boost immune system and in sleeping disorders. Severe deficiency of Vitamin B12 can lead to pernicious anemia. It is also used for lowering high homocysteine levels which may contribute to heart disease, asthma, AIDS, to prevent cervical and other cancers, memory loss, osteoporosis, allergies and skin infections. It also helps to prevent atherosclerosis, multiple sclerosis, and kidney and gum disease. Vitamin B12 is added in almost all multi-vitamin B complex supplements. Deficiency of Vitamin B12 in infants can lead to megaloblastic anemia, delayed developments and movement disorders. Studies have proved that when used in combination with folic acid, it can prevent heart diseases.

Vitamin B2 is a water-soluble vitamin with no known toxic effects. Riboflavin (Vitamin B2) is necessary in the oxidative process of metabolism. It is also sometimes used to correct certain enzyme deficiencies and improve mental processes.

Vitamin B6 is soluble in water and is essential for good health. Our nervous system is dependent on this vitamin to function properly. It keeps the thymus, lymph nodes and the spleen that make white blood cells healthy, through cellular growth and protein metabolism. A deficiency in this vitamin can lead to a weakened ability to fight infections and will weaken the immune system. Vitamin B6 helps in the formation of Hemoglobin which increases the oxygen that is carried to the tissues. A deficiency can cause a type of anemia. Vitamin B6 helps to convert carbohydrates and other nutrients into glucose which maintains the sugar levels in our blood stream. Vitamin B6 is available in meat, fish, fortified cereals, poultry, some fruits and vegetables.
