High doses of Vitamin C could double a man's risk of painful kidney stones.

Authors of the study said this is important information for the public to be aware of.

Those with a history of kidney stones should consult their doctor before taking high doses of Vitamin C supplements.

Researchers have suspected that large amounts of Vitamin C may increase kidney stones because the body breaks down the vitamin into a substance called Oxelate a component of the stones.

The U.S. government currently recommends about 75- to 90 milligrams as a safe amount for most adults.
