Are there risks associated with using vitamin c ?

Large doses of vitamin c are tolerated fairly well in healthy individuals, and some people have taken from 5,000 to 10,000 milligrams each day for several years without having any serious side effects. However, it is possible to consume too much of this vitamin. More than 1,000 milligrams of vitamin c has been known to cause frequent urination and mild diarrhea. Facial flushing, headaches, stomach cramps, nausea, or vomiting are other symptoms of too much vitamin C in the diet.
