As best I recall from the newpapers, the kidney suffered only when true
mega-doses of the stuff were taken, a la Pauling.  The kidneys excrete
excess vitamin C (and other water-soluble vitamins), which is why an
over-dose of them seems less critical than one of an oil-soluble vitamin
(like A).  However, folks taking 3 grams or more per day were found to
develope kidney problems (at least that is the ball park I remember).
Does anyone know about the effects of chronic ingestion of 1 gram/day
or the effects of short-term use of larger amounts?
