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.

Cellulose is the structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Cellulose is not digestible by humans and is often referred to as 'dietary fiber' or 'roughage', acting as a hydrophilic bulking agent for feces.

Dextrin is a low-molecular-weight carbohydrate produced by the hydrolysis of starch. Dextrins find widespread use due to their non-toxicity and their low price. They are used as water-soluble glues, as thickening agents in food processing, and as binding agent in pharmaceuticals.

Dextrose, also known as Glucose is a type of sugar. It is the main sugar that the body manufactures. The body makes glucose from all three elements of food, protein, fat and carbohydrates, but in largest part from carbohydrates. Glucose serves as the major source of energy for living cells. It is carried to each cell through the bloodstream.

Di-Calcium Phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour and noodle products. It is also used as a tableting agent in some pharmaceutical preparations. It is used as a feed for poultry.

Lecithin is needed by every cell in the body and is a key building block of cell membranes; without it, they would harden. Lecithin protects cells from oxidation and largely comprises the protective sheaths surrounding the brain. It is composed mostly of B vitamins, phosphoric acid, choline, linoleic acid and inositol. Although it is a fatty substance, it is also a fat emulsifier.

Magnesium, which is a mineral used by the body to help maintain muscles, bones, and nerves. Magnesium is also needed for energy metabolism and protein synthesis.

Magnesium Stearate is coommonly used as a filling agent in the manufacture of capsules and tablets, such as vitamins, the source of this ingredient is typically bovine. However, there is an increasing number of vegetarian options in which the product specifically indicates it contains magnesium stearate from vegetable sources.

Maltodextrin is a form of glucose that is found in many foods as an additive. It is easy to digest and is almost flavorless. Maltodextrin is formed mainly from starchy products, such as corn and wheat. The starch in these foods is being used to produce maltodextrin through a process called hydrolisys. Maltodextrin is presently being used as an alternative to sugar because it has the ability to produce a sweet flavoring without as many calories. Although considered a carbohydrate, it has lower levels of properties as compared to carbohydrates, thus keeping the consumer free from worry about health issues. Maltodextrin is an effective and inexpensive way to get the required flavoring you desire in your favorite foods, without having to worry about your health.

Sodium Carboxymethylcellulose, also known as cellulose gum, is a food additive that is is commonly used in dairy based foods and deserts. It may also be used as an bulking agent, emulsifier. stabilizer and/or a thickener.

Sodium Citrate is a salt associated with critic acid. It occurs naturally in a variety of foods, including many fruits. It is also an intermediate product of aerobic metabolism in the human body. When consumed in food or produced in the body, sodium citrate quickly degrades into sodium bicarbonate, which functions as an acid buffer. Some studies suggest that taking sodium citrate as a dietary supplement before high-intensity exercise delays fatigue by increasing the availability of sodium bicarbonate in the muscles.

Stearic Acid is a saturated fatty acid that occurs in many animal and vegetable fats and oils. Stearic acid is useful as an ingredient in making candles, soaps, plastics, oil pastels and cosmetics, and for softening rubber. Stearic acid is used to harden soaps, particularly those made with vegetable oil. Even though stearic acid is a saturated fat, studies have suggested that it has little effect on blood cholesterol levels, because such a high proportion is converted to oleic acid.

Synephrine is an ingredient that is obtained mainly from the fruit of a small citrus tree, the Citrus aurantium, also known as bitter orange, zhi shi and sour orange. Synephrine is viewed as the safer version of ephedrine, whereby the properties include weight loss, increased fat burning, raised metabolism, as well as boosted energy levels. With such properties, this drug became instantly popular with the weight loss and control circles, but also with the body building community, and is now used in Metabolife Ultra where fat burning and higher energy level properties are eagerly sought after. Initial research show stimulation of beta-3 receptors, whereby no increased heart rate or blood pressure was observed. It seems that synephrine induces lipolysis and stimulates similarly to caffeine. Some have also observed that synephrine suppresses appetite and increases the metabolic rate.
