Gamma-aminobutyric acid, or GABA, is a nonessential amino acid found in high concentrations in the brain and eyes. GABA is formed from glutamic acid with the aid of vitamin B6. Usually the brain is capable of producing sufficient GABA, but due to a variety of environmental or health reasons, levels can drop. The result can be anxiety, irritability, or insomnia. Low GABA levels have also been associated with depression.
GABA is the primary inhibitory neurotransmitter in the central nervous system. In this role, it helps prevent transmission of messages from one cell to another. This means GABA can help prevent anxiety or stress-related messages from reaching the brain. GABA plays a key role in how the central nervous system responds to stressful situations. GABA can help encourage relaxation and sleep.
GABA also affects the anterior pituitary gland, prompting it to release more human growth hormone (HGH). HGH contributes to muscle growth and limits the development of fat cells.
In some studies regular GABA supplementation led to excess fat loss and better sleep, but further research is necessary to establish specific health benefits from GABA supplementation.
Suggested Use: As a dietary supplement, take 1 capsule 2 to 3 times daily as needed, preferably with juice or water on an empty stomach.
