Key Points:

  • Excess Vitamin C intake has been shown to increase kidney stone risk

  • Kidney stone suffers, especially, should monitor their daily vitamin C intake


Taking high doses of vitamin C supplements, 500 mg or more a day on a regular basis, has been shown to increase the risk of developing kidney stones in some people. More so if you have had kidney stones in the past or have family members who have had them. If you are at risk for developing kidney stones you should not take more than the recommended daily allowance of vitamin C.The recommended daily allowance of vitamin C for women is 75 mg and 90 mg for men.

Did you know that Vitamin C is found in many of our  healthy food choices? 

  • Broccoli

  • Cauliflower

  • Mangoes

  • Oranges

  • Strawberries 

  • Kale 

All the above are naturally good sources of vitamin C. Did you know one serving of many of these foods contain the total recommended daily allowance of vitamin C? Taking a vitamin C supplement or a vitamin C containing multivitamin as well? You may be getting too much vitamin C, possibly increasing your risk of kidney stone formation.

C-ERO: a zero-vitamin-C multivitamin was designed with just that in mind. Specifically formulated by physicians to help prevent kidney stones while providing you with your daily vitamin needs. Taking just 2 capsules of C-ERO a day along with plenty of water and healthy food choices can help stop kidney stone formation.
