Caffeine is the most widely used legal stimulant of the central nervous system and is also used in Metabolife Ultra, 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.

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 is one of the most important sources of energy for the human body. Also known as glucose, it is the main sugar manufactured by the body. This fast acting carbohydrate spikes the level of insulin to a great extent and shuttles creatine molecules in place where it should be. Dextrose is also preferred for restoring the level of muscle glycogen. Moderately sweet, Dextrose occurs in food naturally. Usually found in a powdery form, you can mix it with protein to make a healthy shake. It will not only help you get the required insulin spike but also give your muscles the energy they lost during a strenuous exercise regime. When mixing with protein you can keep the ratio of 2:1. If your weight is anywhere between 75-80 kilograms, don’t consume more than 50 grams of dextrose

Di-Calcium Phosphate is a calcium supplement. Taking di-calcium phosphate can prevent osteorporosis. Although calcium is found in all dairy products like cottage cheese, cheese and yoghurt, milk etc. it is not sufficient to sustain the bones throughout our life beacuse calcium is essential for other things too; like for regulating blood pressure, skeletal maintainance, stimulation of hormone secretion and for controlling the heart beat. Calcium needs to be replenished continously as it gets flushed out from our body due to perspiration and toilet use. Di-calcium phosphate is available in the form of chewable tablets, tablets and in liquid form as well. It is also available in combination with minerals and vitamins. On an average an adult requires 1000 mg to 1200 mg of calcium everyday.

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 is the chemical element found in the periodic table with the atomic number 12. This alkaline earth metal is one of ten most common elements in the known universe and also very prominently present in the human body. It manipulates polyphosphate compounds, most prominently the DNA, RNA and the ATP. Numerous enzymes rely on magnesium ions to function properly. Most common application of magnesium in medicine may be the addition to antacids and laxatives. This metal is not found as a free element naturally on Earth, generally the metal is obtained through electrolysis of magnesium salts. The most common deficiency in the United States with staggering two thirds of the population is the magnesium deficiency. Magnesium can be obtained through vegetables, tea, cocoa, cereals, coffee, nuts and spices.

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 an easily digested carbohydrate.

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 a drug that is deemed to selectively bind to and also activate alpha adrenergic receptors. Mainly used as a vasoconstrictor in asthma, glaucoma, circulatory failure and nasal congestion, this compound is currently propagated as a weight loss agent. The alleged function synephrine is providing include fat burning, energy level and metabolism increase and promotion of weight loss. Synephrine, also known as oxedrine, is the widely accepted replacement for ephedrine. The natural source of synephrine is the citrus aurantium fruit, better known as bitter orange. Bitter orange extracts, which contain synephrine, are known to stimulate the alpha-1 adrenergic receptor, thereby constricting blood vessels and increasing the heart rate as well as blood pressure, effecting in an increased energy use.
