GABA (gamma-aminobutyric acid) strikes a balance between the excitation and inhibition of the brain. This abundant inhibitory neurotransmitter is vital for our well being, as it brings on relaxation and sleep. Due to its stimulating effect on the anterior pituitary, it increases the levels of Human Growth Hormone or HGH that is very anabolic and lipotropic. Obviously, the use of GABA supplement has a positive effect on the anabolic (muscle building) and lipotropic (fat preventing) effects. Like all other supplements, GABA may also cause mild side effects if taken more than the recommended dose. Some of the side effects of GABA include mild tingling sensation around the face and neck area and slight change in breathing patterns or heart rate that normalize in a short while. Thankfully, GABA side effects are not so severe. Due to its mild sedative effect, you must ideally take GABA before going to bed.

Gelatin constitutes the shells of pharmaceutical capsules in order to make them easier to swallow. Gelatin is a translucent, colourless, brittle, nearly tasteless solid substance, extracted from the collagen inside animals' connective tissue. It has been commonly used as a gelling agent in food, pharmaceutical, photography, and cosmetic manufacturing.

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.

Melatonin refers to a hormone made by a brain part called the pineal. Melatonin helps bodies in understanding the time to go to bed and sleep and also the time to wake up. Melatonin is also available in pill form as they are available in natural and synthetic forms. Natural melatonin is manufactured from the pineal glands of the animals and this can get contaminated with virus. This is the reason that it is not recommended. Synthetic melatonin has no risk involved. Melatonin is used in treating insomnia and prevents jet lag. Melatonin promotes health or treats disease has very little scientific evidence. Some people have reported headache, stomach discomfort and depression, however further study is being done. Melatonin is available without the prescription of a doctor in the drug stores and health food stores in the United States. But, as it is not regulated by the government, the safety, purity and effectiveness is far from being guaranteed.

Phosphatidylcholine is a key phospholipid constituent of cell membranes hepatic lipoproteins and bile. It is commonly used in cell signaling pathways. Phosphatidylethanolamine can prove helpful in treating Alzheimer. Brains affected by Alzheimer comprise fewer synapses and decreased levels of synaptic proteins, membrane phosphatides, choline and DHA. Phosphatidylethanolamine utilizes pyrimidine and a PUFA (for example, docosahexaenoic acid), which can significantly enhance levels of membrane phosphatide and synaptic protein in gerbil brains. Phosphatidylethanolamine also helps regulate homocysteine. It is synthesized by two pathways, CDP-choline pathway and methylation of phosphatidylethanolamine by phosphatidylethanolamine N-methyltransferase (PEMT). Recent research has suggested that PEMT is a significant consumer of methyl groups from S-adenosylmethionine (SAM) and plays an important role in determining homocysteine pools.

Propionyl Carnitine ethyl ester is a short chain of carnitine ester. It is commonly used for supporting aging male’s health and reducing fatigue. It helps transport fatty acids into the muscle cells, stimulating the production of more energy. It improves the metabolism and helps burn fats. It ensures that the fats are burned first to use for energy. It also fights free radicals damages in the body. It is also improves blood circulation, and is good for preventing and treating angina, heart attack, and other heart conditions. Aside from balancing cholesterol level, it also helps in maintaining the blood sugar level. It also help men with regards to erection problems.

Usnic Acid is an extract of lichen, which is derived from certain classes of lichen. It is widely used in preparation of cosmetic products, toothpastes, medicine, hair shampoos, and perfumery. In some composition Usnic acid is used as an active principle, and in some composition it used as preservative. Usnic acid also helps in reducing weight. Due to weight reducing property of Usnic acids, Usnic acid and its salts are used as a food supplement for those who want to reduce their weight. However, there is no compact scientific proof behind the fact. Usnic acid has adverse effects also, it has been reported that due to consumption usnic acid liver can be damaged.

Vitamin E, an anti-oxidant nutrient, neutralizes free radicals in the human body to prevent cell damage. This fat-soluble vitamin not only aids the formation of red blood cells but also helps in the absorption of vitamins A, C and K. It is also very helpful to fight various ailments. Since the human body cannot produce vitamin E on its own; it has to be incorporated in our daily diet. This can be done either by consuming foods that are rich in vitamin E or by taking vitamin E supplements. The RDA for adult males is 10 mg. while 8 mg. is the daily requirement for adult females. Expecting and nursing women should compulsorily take 10 mg. of vitamin E supplements. Vitamin E supplements are most effective when consumed with food.
