I get the following inquiry more often than I care to hear and it is “My doctor told me that excessive vitamin C intake can cause kidney stones. Is this true?” My answer is an emphatic, NO!  This myth was perpetrated by the late Victor Herbert who was a notorious anti-vitamin shill.  The myth has been carried on for decades despite evidence to the contrary. 

For a nice review of the issue, go to Chris Gupta’s blog site http://www.newmediaexplorer.org/cgi-bin/mt-tb.r484.cgi/1891 and read up on the issue.  So the next time a doctor tells you to cut back on the vitamin C because it causes kidney stones, your response should be – Read the literature and realize what you just said was wrong.
