GABA, Gamma Aminobutyric Acid, is an amino acid classified as a neurotransmitter (A neurotransmitter is a substance that transmits nerve impulses across a synapse. A synapse is a region where nerve impulses are transmitted across axon terminals.)
GABAs high concentration in the hypothalamus suggests this amino acid plays a significant role in hypothalamic-pituitary function. The hypothalamus is a region of the posterior section of the brain and is the regulating center for visceral (instinctive) functions such as sleep cycles, body temperature, and the activity of the pituitary gland.
The pituitary gland is the master endocrine gland effecting all hormonal functions of the body. One primary hormone of concern to the athlete is growth hormone (GH) and its various hormonal constituents.
The amino acid GABA has been shown in numerous studies to promote significant increases in plasma growth hormone levels.
Take 2 to 5 grams before going to bed.
There have been literally hundreds of clinical studies on
GABA and numerous studies on GABAs ability to elevate growth hormone levels. As with most nutritional studies,
GABA research has come directly from the medical community. One noted study from the First Medical Clinic at the University of Milan in Milan, Italy titled, Effect of acute and repeated administration of gamma aminobutyric acid (GABA) on growth hormone and prolactin secretion in man, shows just how effective
GABA is.
