Abstract
The reduced and total ascorbic acid contents of the blood and urine of 7 healthy young women were determined for periods on a low-vitamin-C basal diet with daily supplements of: (a) orange juice containing 65 mg of reduced ascorbic acid or (b), norit-treated orange juice containing 65 mg of dehydroascorbic acid. When dehydroascorbic acid was fed, the levels of reduced ascorbic acid in blood serum and in urine were comparable to those obtained when the reduced form of the vitamin was given, indicating satisfactory utilization of dehydroascorbic acid.
