Look at my comment #36. Recommendations 1. Where I suggest taking 1 gram in the morning and 1 gram in the evening. This is based on the idea that animals our size produce 2 to 4 grams of C a day. If that amount gives you burning urine or acid farts, then try 500 mg. morning and evening. If you read the links provided at #36 you will learn a lot. Each of us has individual needs, and they change with stress and illness. I have allergies: house dust, cool weather molds, cigarette smoke, ragweed. I have been taking 3 to 6 grams a day for over 45 years. When my nose gets stuffy I take 500 mg. or a gram or 2 and the nose opens up in a few minutes.
The link below has a lot of varied information at “Daily requirement.” Linus Pauling recommended a lot. Now that he is dead I think his Institute has been forced to lower its recommendations a lot. Politics and Big Pharma in action probably.

That’s 2000 mg. everyday !! Don’t you get diahrea from taking that much Vitamin C? I only take half of that dosage daily.
