Caffeine is a methylated xenthine discovered in 1819 by Friedrich Ferdinand Runge, a German chemist. Sources of Caffeine include beans, fruit and leaves of some plants. Caffeine available for human consumption is most commonly extracted from the coffee plant cherries and tea bush leaves, as well as foods and drinks that contain products derived from the kola nut. Caffeine can temporarily reduce the sensation of being tired; however, this does not mean that it eliminates the need for sleep. Generally, twenty five to fifty milligrams of caffeine is enough for most consumers to report an increase in alertness and arousal. Caffeine should be not be consumed by those with fecal incontinence as it relaxes the internal anal sphincter muscles.

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.

Green Tea Extract is very popular with the health conscious community, mainly because of the broad antioxidant features, which are provided by the green tea catechins. It is a very popular nutritional supplement, much more popular than regular green tea, because several green tea extract products have no caffeine. Caffeine is actually contained in larger quantities in green tea than in coffee. Besides the already mentioned catechins, further polyphenols are included in the Asian tea favorite. Green tea furthermore contains carotenoids, ascorbic acid – more commonly known as Vitamin C, Minerals and tocopherols. While there are many proven qualities of green tea extracts, some lesser researched effects have been observed, like reduction of LDL cholesterol, increasing the levels of norepinephrine, weight loss and additional antioxidant qualities.

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.

Kola Nut has a euphoric and stimulating effect on the heart and central nervous system and produces a heightened state of euphoria and well-being.

L-Phenylalanine is one of the two forms of the essential amino acid phenylalanine. L-phenylalanine is naturally occurring while its isomer, D-phenylalanine is produced in artificially and may act differently in the body. The body converts this amino acid into another essential amino acid, L-tyrosine, which in turn becomes dopamine, epinephrine or norepinephrine. Because of its conversion to the three neurotransmitters, scientists hypothesize that phenylalanine can aid in treating depression. However, researches about this hypothesis were done in the 1970s and 1980s such that rigorous and strict scientific process was not followed thoroughly. Therefore, L-phenylalanine’s effect on depression is yet to be investigated further. Aside from being an indirect precursor to the catecholamines and dopamine, it is the antecedent of the neuromodulator phenylethylamine. Phenylethylamine affects the appetite, making it a commonly used appetite suppressant.

Theobromine- The bitter alkaloid found in chocolate is known as theobromine. It comes from the cacoa plant and is found in chocolate as well as chocolate free foods that are consist of theobromine. Theobromine belongs to the methylxanthine class of chemical compounds. It is found in the leaves of the tea plant, the kola or cola nut and acai berries. No bromine is present in theobromine, despite the name. The properties of theobromine are that it is souluble in water, is crystalline, is a bitter powder, is listed as white or colorless in color. It is considered a lesser homologue because it has a lesser effect to caffeine. Theobromine is the kind of isomer which belongs to paraxanthine and theophylline at the same time. It is basically a xanthine having two methyl groups.

Vitamin B12, 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 B16 also known as (DiMethylGlycine) enhances oxygen utilization by the body's tissues. It improves muscle performance,the immune system and the cardiovascular system. This dietary supplicate helps produce improved energy and physical stamina.Vitamin B16 is a detoxifying agent and an antioxidant that protects cells against harmful free radicals.It also reduces lactic acid buildup during strenuous exercise which allows for a greater work out.

White Willow Bark, or Salix alba, is a willow commonly found in Europe and adjacent parts of western and central Asia. The bark of the White Willow has been used for centuries against fevers and to ease pains and aches. Already Hippocrates wrote about the White Willow bark powder two thousand five hundred years ago. The active ingredient of the White Willow bark is called salicin, a relative to aspirin and chemical derivative of the salicylic acid. When ingested, salicin is converted to salicylic acid, a beta hydroxy acid. As a nutritional supplement, White Willow products are being propagated as weight loss additives, whereby the scientific community has yet to provide any corroboration to this allegation. Besides the well known anti inflammatory characteristics, any other uses have not been approved by the FDA.
