Last word on Kidney stones and Vitamin C spoken?

First, yes, we will move reports of toxicity from the general discussion to the toxicity forum.
Second, there a no clinical, placebo controlled, double blind studies in guinea pigs, humans or other non-C producing species that show increased vitamin C produces kidney stones.
Dr. Robert Cathcart's more than 30-years experience (no kidney stones in his patients) indicates that there is something highly protective in high vitamin C regarding kidney stones.
And again, for people with acidic urine, there is a possibility that vitamin C might aggravate a propensity to form stones (we doubt it) and those people should take sodium ascorbate, or enough bicarb that the urine is less acidic. From Paulings review, we can infer that stones form in acidic or alkaline urine, not neutral urine.
