Men Who Take Vitamin C Supplements Have Twice The Risk Of Developing Kidney Stones

Men who take vitamin C supplements regularly run a higher risk of developing kidney stones, according to Swedish research. The research analyzed data from 23,000 men who had no history of kidney stones and who took either no dietary supplements or supplements in the form of vitamin C only. The researchers found that men who take vitamin C supplements (typically 1000 mg per tablet) are twice as likely to develop kidney stones as men who do not take any dietary supplements. The risk increased with greater frequency of use as well. Regular use of multivitamins was not associated with the risk of kidney stones.
