Vitamin C precursor decreases stroke damage in mice

Vitamin C is unable to cross the blood-brain barrier, but the vitamin C precursor dehydroascorbic acid (DHA) can, then is converted into vitamin C within the brain. In this murine study utilizing DHA, brain damage from a stroke was lessened by giving the mice DHA. Vitamin C's antioxidant effect is thought to be responsible for the benefit.
