Gabapentin, a gamma-aminobutyric acid (GABA) analogue, has infrequently been reported to cause liver injury ; however, the causality in the previous reports is contested. Herein, we report a gabapentin-induced hepatocellular injury in a patient without another identifiable cause for acute liver injury.
Does GABA affect the liver?

Does magnesium help with GABA?
One of the key benefits of magnesium is that it increases our gamma-aminobutyric acid (GABA) levels The magnesium binds to and stimulates GABA receptors in the brain, which puts the brakes on brain activity.
Do GABA supplements increase GABA?
Some people need to boost GABA for anxiety, while others want to increase GABA for sleep, and these have shown to be effective for many people. Straight GABA supplements are also available, though some experts argue that they don’t actually work because GABA is not actually reaching the brain.

Does L Theanine cause liver damage?
L-theanine significantly reduced liver cell apoptosis and tissue damage in a dose-dependent manner to near normal state (Fig. 1), indicating that it can alleviate alcohol-induced liver tissue damage.
Is GABA metabolized by the liver?
Over the past 40 years it has become evident that the mammalian liver contains high concentrations of GABA which are carefully regulated by a series of hepatic metabolic pathways and a specific sodium-dependent active transport system.

What drugs does GABA interact with?
Gamma aminobutyric acid (GABA) represents the major inhibitory neurotransmitter of the central nervous system. Ethanol as well as benzodiazepines (BDZs) and some anticonvulsant drugs directly affect GABAA receptors inducing similar anxiolytic, sedativehypnotic, and anticonvulsant effects.
What are the symptoms of low GABA?
In those who are deficient in GABA, feelings of anxiety, stress and worry can be common symptoms, leading to alcohol cravings. Alcohol targets GABA receptors and mimics the effect of this neurotransmitter, helping to relax the mind and body.
