Men who take vitamin C supplements are at higher-than-average risk of developing kidney stones, a new study from Sweden suggests. The findings don't prove the vitamin itself triggers stones to form. But researchers said that because there are no clear benefits tied to taking high-dose vitamin C, people who have had stones in the past might want to think before taking extra supplements.
