100 grams or more!!!: Vitamin C has no known toxic level; it acts as a laxative if you take too much. The sicker you are the more you need; many experts advise taking 2-3000 mg every hour til you get loose stools. High doses of Cal-C-Vita will give lots of D too but safe to take up to 30,000 units of D/day for a week. I advise stopping Efferflu- lowering fever reduces immune function!
