There is a longstanding belief among the mainstream medical community that vitamin C causes kidney stones, which is based on little science.[98] Although recent studies have found a relationship[99] a clear relationship between excess ascorbic acid intake and kidney stone formation has not been generally established.

Guest guest Posted March 18, 2009 Report Share Posted March 18, 2009 Thanks, John, for the scholarly references. I know this to be a controversial area. I would think that the status of one’s kidneys is an important variable in this equation, as well as how well one is maintaining a balanced pH level in the blood. Too bad it is so difficult to get research supported on which nobody will make a huge profit. I’m considering investing in a Kagen water treatment system to address a acid/alkaline balance. Do you have any experience with that?
