How much vitamin c is allowed per day? i have a cold and would like to take vitamin c to reduce symptoms. is 2000 a day ok?

Safe to take 40,000!: There is no know "toxicity" to oral vitamin C though too much can cause loose stools. There is some concern that taking large amounts of Vit C on a longterm basis can increase risk of kidney stones but the evidence is contradictory: http://tinyurl.com/ho9dccc Vit. C won't help your cold much without high doses. I advise 2000 mg every hour until you get loose stools- see http://tinyurl.com/lqevelt
