Vitamin C Works on GABA Receptors in Retina
Research in the Journal of Neuroscience suggests that vitamin C (ascorbic acid) may be needed for the GABA (gamma-aminobutyric acid) receptors in the retina to function properly.
GABA is a neurotransmitter that is responsible for inhibition of nerve impulses and helps protect the nerves from runaway excitation. GABA binds to a GABA receptor where it inhibits the nerves. Vitamin C works in tandem with GABA receptors to maintain the inhibition of the GABA receptors in the retina. This study suggests a possible larger role in brain function for GABA receptors and vitamin C.
In the study the researchers used electrodes on thin slices of retina from goldfish, they noted that vitamin C regulated the response of the GABA receptors. The receptors for GABA were enhanced by the presence of vitamin C and decreased significantly when vitamin C was decreased.
No one was aware of this effect before this research, so it may lead to further research into vitamin C’s effect on neurochemistry as related to the neurotransmitter GABA and its receptors.
The doctor speculated that a vitamin C rich diet could possibly be neuroprotective and may aid people prone to glaucoma or epilepsy.
