Caffeine is of course a major component of every day drinks such as tea and coffee and is also included in Thermonex EF. It is claimed that over 70% of the American population take more than 300 milligrams daily. As well as in familiar drinks it is used in energy drinks such as Red Bull as well as in many over the counter analgesics and other medication. Medically it is a as trimethylxanthine, useful as a heart stimulant and it also works as a mild diuretic. It works in the same way as certain drugs, the amphetamines, cocaine, and heroin, all of which work on the action of the brain although in a milder way, and like them it is addictive.

Diiodotyrosine, also known as DIT, is a drug used to treat hyperthyroidism and is often included in dietary supplements designed to increase the metabolism and burn fat. It is considered a synthetic anti-thyroid agent that is used to decrease the amount of hormones the thyroid produces. In some cases it produces a response more quickly than radioactive iodine therapy while not causing the thyroid gland permanent damage. Possible serious side effects of this drug are the suppression of bone marrow which can lead the patient to having a decreased number of blood leucocytes, bronchitis, hepatitis, jaundice, skin rashes, and/or syndromes that are similar to systemic lupus erythematosus.

Evodiamine, a bioactive alkaloid extract from the Evodiae Fructus plant, sometimes called Wu-Chu-Yu. Evodiamine is related to capsaicin, found in cayenne pepper. Evodiamine is a vanilloid receptor agonist, and may enhance lipolytic activity. Evodiamine has been shown to raise the body’s skin temperature and decrease core temperature, which is thought to burn calories and fat for energy.

Green Tea Extract- Camellia sinensis, or more commonly the tea plant is a genus of flowering plants which is generally being used to produce tea, including green tea, oolong, black tea, white tea and pu-erh tea, also called Bolay tea. The different oxidation process makes the final difference. Tea plants can grow out into a tree, but are generally pruned to allow for easy hand picking. While camellia sinensis is being cultivated all around the globe in tropical and subtropical regions, this South and Southeast Asian native is most popular when imported from India and China. Medical uses of tea stem from the traditional Chinese medicine, where it was used as a bronchodilator and to treat angina pectoris, coronary artery disease and peripheral vascular diseases. Green tea extract is used as appetite suppressant and thermogenesis increasing agent.

Iodotyrosone, which is a form of tyrosine with iodine added.

L-Tyrosine, a non-essential amino acid that is used to build protein. It is a precursor dopamine, as well as a precursor to norepinephrine and epinephrine. The body makes L-Tyrosine from the amino acid phenylalanine. Since L-Tyrosine is a precursor of Dopamine, it may raise mental alertness, making it of great use in exercise programs.

Naringin, which is a citrus flavanoid that is found in grapefruit. Naringin is commonly used in energy supplements as it may extend the duration of the effects of caffeine.

Octopamine is a biogenic substance which is containing an amine group, apparently related to noradrenaline, which is a catecholamine functioning as both, neurotransmitter and a hormone. Similar to norepinephrine, which is another name for noradrenaline, octopamine may act as a stress hormone, triggering increased heart rate, energy consumption and blood flow, even the blood pressure. One side effect of octopamine is apparently the release of fat from the adipocytes, which are the fat cells where excess energy is being stored. This side effect prompted the use of octopamine as a dietary supplement aimed at weight loss, but used in combination with other stimulants. Octopamine has been discovered in the middle of the twentieth century, but the use as a fat removal agent is very recent.

Synephrine or oxedrine is a drug derived from bitter orange or Citrus aurantium. It is an aromatic compound with the systematic name 4-[1-hydroxy-2-(methylamino)ethyl]phenol which indicates that it has an attached hydroxyl group at para position and a methyl amino group at another position. It is not one of those compounds on which an extensive scientific study has been done. However, it has some positional isomers such as the neosynephrine as well as other compounds. Studies indicate that it could act as a Beta-3 adrenergic receptor which means that if taken as a supplement it enhances the breakdown of fat to release energy and also increases heat production in the muscles.

Yerba Matte is potent and refers to a drink that is brewed with dried leaves. It belongs to the holly family that is an evergreen member. This grows in Peru, Argentina, Brazil and Chile. This is as well found in plenty in Paraguay. The Yerba Mate plant is considered as stimulant, aromatic, astringent, bitter, purgative, diuretic and good for inducing sweat and reducing fever. Yerba mate contains many minerals and vitamins. The Yerba Mate leaf has nutrition and antioxidants in plenty and hence North Americans prepare strong tea using this leaf. Yerba mate powder is used to boost immunity and to detoxify blood, restore hair color, combat fatigue, tone nervous system, stimulate mind, control appetite, retard aging, reduce stress and as well eliminate insomnia. The tea is preferred with sugar or some people add mint and few replace the water with milk. The extraction can be done repetitively so that the properties stay beneficial.
