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 is a solid substance that comes from the collagen found inside the skin and bones of some animals, mostly from pigs, cattles and other domesticated animals. The collagen becomes gelatin after undergoing the process of partial hydrolysis. Gelatin is a protein that is translucent, colorless, odor-free, breakable and almost without taste. One property of gelatin is its ability to melt easily when heated and in the same way, solidify when cooled. Commonly, it is being utilized as a gelling agent in many industries like food, pharmaceuticals and cosmetics. It's also known by its E number which is E441.

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, a naturally produced chemical messenger made by the pinealocytes, the cells in the pineal gland, which is located in the brain. Melatonin is involved in the circadian cycle, where it is believed that it chemically lowers the body temperature and causes drowsiness. The pineal gland produces melatonin only when it is dark, i.e. during the night. It is furthermore believed that melatonin interacts with leptin, whereby the leptin levels are lowered. Actually it was found that the interaction with insulin stimulated the leptin levels, which seems to be responsible for appetite suppression during sleep. Further investigation provided evidence that melatonin displays strong antioxidant properties. N-Acetyl-5-Methoxytryptamine, or melatonin, has been studied extensively for treatment of many diseases, including treatment of drug abuse, cancer, seasonal affective disorder and depression.

Phosphatidylcholine - a major component of biological membranes and can be isolated from egg yolk or soy beans. This extraction of the Phosphatidylcholine is done using hexane. Phosphatidylcholine is in fact a primary dietary source of choline, an essential nutrient which can also be synthesised by the body. Phosphatidylcholine is composed of a phosphate group, 2 fatty acids and choline. The fatty acids are what make Phosphatidylcholine valuable for promoting health. Phosphatidylcholine is important because it provides the body with choline which is required for the proper metabolism of fats as well as regulating the movement of fats in and out of cells. Choline is also need to maintain cell membrane integrity. Phosphatidylcholine also increases the solubility of cholesterol and hence decreases the chances of atherosclerosis.

Phosphatidylethanolamine can prove helpful in treating Alzheimer's. Brains affected by Alzheimer's 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.
