GABA, or Gamma-Aminobutryic Acid

GABA is a powerful amino acid that was first discovered in 1883 in Berlin. GABA is actually classified as a neurotransmitter, which means it helps nerve impulses cross the synapses (gaps) and communicate better. GABA has a great number of positive effects on the nervous system.
In addition, GABA has some startling effects on promoting fat loss. How does this work? GABA stimulates the production of Human Growth Hormone (HGH). It is HGH that has been found in studies to facilitate the metabolism of fats in the body. HGH is also known for it's powerful muscle-building effects.
Increasing HGH is definitely a good thing, especially for bodybuilders. HGH tends to decrease naturally with age, so the older you get, the harder it is to lose fat. That's one reason GABA has become so popular.
Other studies have shown that GABA increases the body's sleeping cycle and patients reported much more vivid dreams. Getting a good night's sleep and obtaining more rest can lead to more energy throughout the day. Not to mention, increasing fat loss and promoting muscle growth also leads to an increase in energy. More energy and feelings of vigour are common side effects of supplementing with GABA.
GABA has been shown to be very effective in treating pain associated with arthritis or the lower back. Most scientific research indicates that the proper amounts of GABA to take per day is a minimum of 2 grams. Better results have been found when supplementing with 5 grams per day. For serious results, studies have found that supplementing between 5 and 18 grams works well. For pain support, GABA can be taken any time and be effective.

Gamma-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian Central Nervous System (CNS). GABA participates in the regulation of neuronal excitability through interaction with specific membrane proteins (the GABAA receptors). The binding of GABA to these postsynaptic receptors, results in an opening of a chloride channel integrated in the receptor which allows the entry of Cl- and consequently leads to hyperpolarization of the recipient cell. The action of GABA is allosterically modulated by a wide variety of chemical entities which interact with distinct binding sites at the GABAA receptor complex. One of the most thoroughly investigated modulatory site is the benzodiazepine binding site. The benzodiazepines constitute a well-known class of therapeutics displaying hypnotic, anxiolytic and anticonvulsant effects. Their usefulness, however, is limited by a broad range of side effects comprising:

• Sedation
• Ataxia
• Amnesia
• Alcohol and barbiturate potentiation
• Tolerance development
• Abuse potential

Consequently, there has been an intensive search for modulatory agents with an improved profile, and a diversity of chemical entities distinct from the benzodiazepines, but with GABA modulatory effects have been identified. The existence of endogenous ligands for the GABAA receptor complex beside GABA has often been described, but their role in the regulation of GABA action is still a matter of controversy. The progress of molecular biology during the last decade has contributed enormously to the understanding of benzodiazepine receptor pharmacology. A total of 14 GABAA receptor subunits have been cloned from mammalian brain and have been expressed/co-expressed in stable cell lines. These transfected cells constitute an important tool in the characterization of subtype selective ligands. In spite of the rapidly expanding knowledge of the molecular and pharmacological mechanisms involved in GABA/benzodiazepine related CNS disorders, the identification of clinically selective acting drugs is still to come.
