Effect of vitamin C on neutrophil function after high-intensity exercise
This study used 2g of Vit C for one week in runners to determine if Vit C could alter the reduction in neutrophil function commonly seen in long distance runners. No difference was seen. However, there are two issues with this study. First of all, it was small (10 runners), and 2g of Vit C may be way too low of a dose for this application. I recommend 1-2g/day for the average person, and the amount of oxidative free radical production occurring in a long distance runner is very high. I would like to see if intakes on the range of 3-6g/day would make an impact.
