Caffeine is a stimulant that is used to stay awake and it gives mental alertness from fatigue. This is used as an adjunct for pain relief and also as energy accelerates. Caffeine is a non-prescription drug easily available as over the counter medication and comes in combination to acquire relief from headache and pain. Caffeine increases the mental alertness by offering the required energy for exercise training and weight loss. Caffeine cannot be considered as a mere stimulant as it reaches deep into muscles and provides power that is long lasting. Caffeine taken before any work out is also great as it fights the fatigue and keeps the person ready for the workout. Dieters also find caffeine as the solution as they feel sluggish. This is a no-calorie stimulant and does its job effectively and quickly. Caffeine anhydrous is found even in one or two coffee cups. However, this limitation is recommended as excess caffeine may result in irritability, rapid heart beat, nervousness and sleeplessness.

Ephedra Extract is extracted from the plant Ephedra sinica, It has been used in traditional Chinese medicine for the treatment of asthma and hay fever. Ephedra is used both as a stimulant and a thermogenic, which stimulates the brain, increases heart rate, increases blood pressure and expands bronchial tubes (making breathing easier). These effects are due to its ephedrine and pseudoephedrine content. Research also shows that it can be used as a precursor in the illicit manufacture of methamphetamine. Ephedra extracts are also used by athletes to enhance athletic performance. It is also used in supplements for weight loss.

Hoodia Gordonii is an extract from the Hoodia plant of South West Africa. It is one of the fore runners in weight loss programs. Quenching thirst and providing energy are two of the numerous uses of the plant extract. The extract reduces gastric acid output in the stomach to a large extent, ranging from 40 – 60%. Aside from repressing hunger, Hoodia raises the overall energy levels in the body and will make a person feel completely healthy – both mentally and physically. Hoodia Gordonii is known to be extremely effective and does not have side effects such as dizziness, causing an increase of the heart beat or body temperature and sleeplessness. Hoodia Gordonii, however, should not be used during pregnancy and by nursing mothers.

L-Tyrosine is a non essential amino acid occurring in the body. L-Tyrosine may be created from the synthesis of phenylalanine which is also an amino acid. It is one of the building blocks of proteins in the body. It is also a precursor for several neurotransmitters such as L-dopa, dopamine, epinephrine and norepinephrine. It helps treat and prevent illness such as Parkinson’s disease, Alzheimer’s disease, depression and other such mood disorders. It also helps protect the body from free radical damages. It also helps protect the skin from UV rays damages on the skin by aiding in the production of melanin. It also helps in increasing the metabolic rate that speeds up muscle building and fat loss. It also increases the endurance.

Phenylethlamine HCL is a salt of phenylethylamine. It is a crystalline solid and is formed by treating phenylethylamine with HCl. Its IUPAC name is 2 phenylethylamine HCl. The scientific name elucidates its chemical structure. It is an aromatic compound meaning that it has a basic benzene ring. It further has a two carbon chain attached at position 2 of the ring and the chain terminates in an amino group. It occurs naturally in some foods like chocolates but the food item might get metabolized too quickly sometimes for it to have a significant effect on the body. This substance has quite profound effects on the level of dopamine in the central nervous system, provided it passes the blood brain barrier. It increases dopamine level and at the same time inhibits dopamine transmitters resulting in a buildup of dopamine in the brain. While excessive levels of dopamine in the CNS are not healthy, the neurotransmitter does regulate cognition, mood, voluntary movement and other brain functions.

Raspberry Ketones have become a chief ingredient in various food supplements these days due to their fat-burning properties. They are a chemical compound found in the fruit that give it its characteristic fruity smell and flavor. While it has most of the goodness of capsaicin that is also known to improve metabolism, it does not lead to side effects like stomach irritation. Intake of raspberry ketones leads to increase in production of a hormone called norepineprine that enhances the metabolic rate of the body by increasing its temperature. Studies reveal that raspberry ketone supplements reduce the body's ability to synthesize dietary fat. Raspberry ketone supplements not just help in reducing the fat, but also help in reducing fatty deposits in blood vessels when the norepineprine levels in the blood increase.

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.

Vitamin B6, also known as Pyridoxine, Vitamin B6 is an essential vitamin to aid in the formation of healthy red blood cells and supports more vital bodily functions than any other vitamin. A water-soluble vitamin, Vitamin B6 is needed to release energy from the food we eat. Vitamin B6 cannot be stored in the body, so it must be obtained daily from either food or supplements. Vitamin B6’s role as a coenzyme involved in the metabolism of carbohydrates, fats, and proteins is what makes it important for dieters. Vitamin B6 is also responsible for the manufacture of hormones, red blood cells, neurotransmitters, enzymes, and prostaglandins. Vitamin B6 is required for the production of seratonin, a brain neurotransmitter that controls mood, appetite, sleep patterns, and sensitivity to pain. For weight loss, dieters should include vitamin B6 to increase their metabolism while rounding out a healthy diet.

White Willow Bark, less commonly known as salix alba, is extracted from a plant native to Europe and parts of Asia. The great physician Hippocrates first mentioned the use of White willow extract in his writings in 5th century BC and it has been touted as a powerful supplement for several different uses ever since. It is commonly used as a pain reliever (particularly for back pain and arthritis), fever reducer, and inflammation reducer. Although aspirin was eventually invented using the same base as White willow extract, many purists and natural health enthusiasts prefer to use White willow extract, which is considered to be nature’s aspirin.
