This paper says: "vitamin A, vitamin C, folate, and {alpha}-tocopherol from supplements were positively associated with the serum GGT concentration". The serum GGT levels reflect the degree of oxidative stress. So, if the findings of this study are up to something, then ingestion of mega dose of vitamin C could do more harm than good.
