Vitamin C Study

Synopsis from: "Comparative bioavailability to humans of ascorbic acid alone or in a citrus extract"; Joe A.Vinson and Pratima Bose, 1988 Am. J. Clin. Nutr.,48:601-604

Side by side study compares the bioavailability of synthetic ascorbic acid (ascorbic acid) and FoodState vitamin C in humans. The effect of a single 500mg ascorbic acid dose of the two forms and a placebo on plasma concentration vs. time curve showed that FoodState vitamin C was 35% more absorbed and was more gradually absorbed than ascorbic acid alone. The majority of the subjects (75%) in this study excreted less vitamin C when they consumed FoodState vitamin C, whereas, the ones who consumed ascorbic acid alone excreted more ascorbic acid, indicating that less was absorbed by the subjects. 

FoodState vitamin C is 1.35 times greater absorbed than plain ascorbic acid and is retained by the body longer similar to whole natural foods rich in vitamin C.
