The approach to abnormal urinary vitamin C levels depends on whether they are too low or too high:
For Low Vitamin C in Urine
- Increase Dietary Intake
- Add vitamin C-rich foods to your diet, such as oranges, strawberries, kiwi, bell peppers, broccoli, and spinach.
- Address Absorption Issues
- If absorption problems (e.g., due to gastrointestinal disorders) are suspected, consider supplements in consultation with a healthcare provider.
- Antioxidant Support
- Address oxidative stress with a well-rounded antioxidant-rich diet, including other nutrients like vitamin E and selenium.
For High Vitamin C in Urine
- Reduce Supplement Use
- Cut back on high-dose vitamin C supplements unless medically necessary. The recommended daily allowance (RDA) for adults is 75–90 mg per day, with an upper limit of 2,000 mg per day.
- Hydration
- Stay well-hydrated to prevent potential kidney stone formation, especially if you consume high doses of vitamin C.
- Reassess Diet
- Review dietary habits and avoid excessive consumption of fortified foods or supplements.
General Recommendations
- Regular Monitoring
- If vitamin C levels in urine are persistently abnormal, consider follow-up tests to assess overall vitamin status and kidney function.
- Holistic Nutritional Approach
- Balance vitamin C intake with other essential nutrients to support overall health.
