GABA (gamma-aminobutyric acid)
GABA Research & Studies
World Class Nutrition has the largest selection of GABA Supplements.
Gaba(gamma-aminobutyric acid) is the most important and abundant inhibitory neurotransmitter in the brain (it's actually an amino acid classified as a neurotransmitter). It helps induce relaxation and sleep. It acts as a "balancer" for the brain where excitation of the brain is balanced with inhibition.
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.
There are many studies done on GABA and GABA effects, and studies have show GABA to promote significant increase in plasma growth hormone levels.
One study found that 90 minutes after GABA supplementation, HGH levels increased 5 times. This research studied 19 subjects who took GABA compared to 18 placebo subjects, and 5 grams of GABA was administered orally to the GABA group. After 90 minutes HGH levels in the GABA group were found to have increased by 5 fold.
Research shows that at least 2 grams of GABA should be taken for it to be effective. 5g is shown to be more effective, and the effectiveness of GABA is maxed out at 18 grams. GABA is effective even when taken orally. GABA Side Effects
There are few if any side effects of GABA. Some users have experienced some mild tingling sensations around the face and neck area after supplementing GABA. Some users also notice a brief and mild change in heart rate or breathing patterns. These GABA side effects quickly disappear and are not harmful. Not everyone experiences these side effects.
GABA also has a slightly sedative effect, which makes it ideal to take before going to bed.
