I think I didn't remember right on that. So much info going by so fast. Actually it seems impossible to absorb too much Vitamin C. I'm not finished researching, but it does seem that really massive doses, like 100 grams and over, were administered by Klenner for just a couple of days in cases of acute illness.
I guess it's just not practical or cost effective for most people to keep on taking that much - and may not be necessary once they get well.
