Vitamin C supplements boost kidney stone risk in men
Men who take vitamin C supplements regularly run a higher risk of developing kidney stones, Swedish researchers have warned.
The research is based on data from a large population-based study of men from Västmanland and Örebro counties, who were monitored for 11 years.
A total of 23,355 men were identified who had no history of kidney stones and who took either no dietary supplements or supplements in the form of vitamin C only. During the study period, 436 of the participants developed kidney stones that required medical attention.
