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 treatment increased grafted β-cell This effect on heart rate was however not prevented by coadministration of picrotoxin (Figure 5(a)), suggesting that GABA A receptors are not involved in the bradycardiac effect.
