A study was published online in the June 29 issue of the Journal of Neuroscience.
Here are some conclusions:
Cells in the retina need to be 'bathed' in relatively high doses of vitamin C, inside and out, to function properly. said Because the retina is part of the central nervous system, this suggests there's likely an important role for vitamin C throughout our brains, to a degree we had not realized before.
The function of vitamin C in the brain is not well understood.
However, it is known that when the human body is deprived of vitamin C, the vitamin stays in the brain longer than anyplace else in the body.
This suggests that the brain is the last place you want to lose vitamin C.
This also may offer a clue as to why scurvy — which results from a severe lack of vitamin C — acts the way it does.
One of the common symptoms of scurvy is depression, and that may come from the lack of vitamin C in the brain.
It is currently widely believed that vitamin C helps protect against glaucoma.
There are many other known benefits to vitamin C.
This research was performed by Henrique von Gersdorff, Ph.D., a senior scientist at OHSU's Vollum Institute, and other scientists at Oregon Health & Science University.
