A member asked:
I have a cold coming on and a non doctor friend told me to take 2000 mg vita c 3 times a day. is that amount safe and for how many days?
A doctor has provided 1 answer
Safe but useless: Megadose vitamin c has been advocated since the 80's by people like linus pauling. Vitamin c is cheap and safe but it has never been shown to prevent, treat, or shorten the duration of colds. The daily dose of vit c is 200mg, any extra you take is flushed from the body in your urine. Washing your hands regularly, eating right, getting plenty of sleep and exercise is more effective prevention.
