Take-home message: - gamma-Aminobutyric acid (GABA) is a major neurotransmitter that regulates much of our brain function. It was previously thought that ingested GABA could not cross the blood-brain barrier, but new research suggests that it may be able to. - Drugs that mimic the action of GABA are numerous, work in a variety of ways, and can have effects ranging from treating epilepsy to 2020-08-07 · Low blood pressure and increased heart rate; Loss of consciousness; Sedation and sleepiness; Agitation; Excessive muscle relaxation or tremors; Hallucinations; Nausea and vomiting; Tolerance; Serotonin syndrome; Side effects are much more likely at doses over 1 g/day, while high doses (3 g/day or more) can be very dangerous. GABA improves sleep and increases the release of growth hormone, but the effect of supplementation is often modest.

Since taking GABA on its own won't help, here are a few ways to increase absorption rates. Low GABA activity has been shown to exacerbate mental illnesses, including depression, social anxiety disorder, and post-traumatic stress disorder (PTSD). Symptoms of low GABA include feeling disorganized, having racing thoughts, increased heart rate and being unable to relax or get restful sleep.
