Vitamin C Supplements May Increase Kidney Stone Risk

Vitamin C Supplements May Increase Kidney Stone Risk

Vitamin C is important for our body, but taking too many supplements can be risky.

A woman named Saku Shukla shared her story of how taking too much vitamin C led to kidney stones.

Doctors say that high doses of vitamin C can turn into something called oxalate, which can combine with calcium and form stones in the kidneys.

This risk is higher for men and people who already have a history of kidney stones or certain health conditions.

To stay safe, it's better to get vitamin C from foods like fruits and vegetables instead of supplements.

Drinking lots of water and eating a balanced diet can also help prevent kidney stones.
