GABA (gamma-aminobutyric acid) is recognized as the most important and the abundant inhibitory neurotransmitter in the brain (it's actually an amino acid classified as a neurotransmitter). It also helps induce relaxation and sleep.
In addition to it's 'balancing' effects, GABA stimulates the anterior pituitary, leading to higher levels of Human Growth Hormone (HGH), and if you didn't know, HGH is very anabolic (muscle building) and lipotropic (fat preventing). So, GABA indirectly enhances these 2 positive effects.
HGH tends to decrease naturally with age, so the older you get, the harder it is to lose fat.
A study conducted by First Medical Clinic at the University of Milan in Milan found that 90 minutes after GABA supplementation, HGH levels increased 5 times.
GABA also has a slightly sedative effect, which makes it ideal to take before going to bed.
Research shows that GABA might play a key role in protecting against depression and anxiety. For instance, a study published in the journal Biological Psychiatry in 2010 indicates that people with major depression may be more likely to have low levels of GABA.
And in a 2009 study from the same journal, researchers found that increasing GABA levels may be useful in treatment of anxiety.
When brain experiences an abundance of nervous tension and stress, it can be caused by a surplus of norepinephrine or epinephrine (adrenaline). To neutralize this extra adrenaline, the brain produces neurotransmitters, one of which is GABA, that have inhibitory effects upon the nervous system.
L-Glutamine is an amino acid that in a precursor to GABA. Using a nutritional supplement that contains L-Glutamine along with a balanced diet can support the natural replenishment of GABA, as well as other neurotransmitters.
