““The brain and the central nervous system have such enormous needs for vitamin C that they actually operate 'vitamin-C pumps' to extract it from the circulating blood and concentrate it in the cerebrospinal fluid, where its level is ten times greater than in the blood. From the cerebrospinalfluid, another pump transfers vitamin C directly into the sheaths enveloping brain and nerve cells, concentrating it by another factor of ten, which means that the cells of the brain and central nervous system are bathed in a solution of vitamin C that is 100 times more concentrated than in blood plasma and other bodily fluids. Vitamin C is obviously very important to the health of brain and nerve cells.””
