GABA, or Gamma-Aminobutyric Acid, is a powerful amino acid that was first discovered in 1883 in Berlin. It 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.

GABA has shown to help stimulate 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 its powerful muscle-building effects. Increasing HGH can definitely be 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.
