10. Cause of Kidney Stones: Excessive Vitamin C Intake
While vitamin C is essential for overall health, consuming excessive amounts can increase the risk of kidney stone formation. When the body metabolizes vitamin C, it produces oxalate as a byproduct. As mentioned earlier, high levels of oxalate in the urine can contribute to the development of calcium oxalate stones.
To reduce the risk of kidney stones, it’s essential to monitor your vitamin C intake and avoid consuming excessive amounts. The recommended daily allowance (RDA) for vitamin C is 90 mg for men and 75 mg for women. It’s generally best to obtain your daily vitamin C requirement from whole food sources such as fruits and vegetables. (10)
