Study Ties Vitamin C Supplements to Increased Risks of Kidney Stones in Men

Study Ties Vitamin C Supplements to Increased Risks of Kidney Stones in MenA new study has linked vitamin C supplements to men's kidney stones.

Above are the findings of a Swedish study, which was run by experts over more than 22,000 men. The findings of the study say (according to researchers) men, who have a higher intake of vitamin C supplements have been noticed to be at higher-than-average risks of developing kidney stones.

"It has long been suspected that high doses of vitamin C may increase the risk of kidney stones as some of the vitamin C absorbed by the body is excreted in urine as oxalate, one of the key components of kidney stones," said lead researcher Ms. Laura Thomas at the Karolinska Institutet in Stockholm.

Ms. Thomas and her team have presented the findings of the study in JAMA Internal medicine. They analyzed data of a large study ran over middle-aged and elderly Swedish men in which they were questioned upon their diet and lifestyle. Their health was tracked for an average of 11 years.

According to the current analysis, data found 907 men, who have regular intake of vitamin C tablets and more than 22,000, who said that they haven't used any nutritional supplements yet.

Among the vitamin C users, 3.4 percent developed kidney stones as compared to 1.8 percent of non-supplement users, found experts.
