Vitamin C in Urine
Also known as ascorbic acid, learn how it impacts your overall health.
What is Vitamin C in Urine?
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for numerous bodily functions, including boosting the immune system, supporting collagen production, aiding in wound healing, and acting as a powerful antioxidant. Unlike fat-soluble vitamins, excess Vitamin C is not stored in the body; instead, it is excreted through urine when levels exceed the body's immediate needs. Measuring Vitamin C in urine can help assess dietary intake, absorption efficiency, and potential deficiencies or excesses. Since Vitamin C is also involved in reducing oxidative stress, understanding its levels can provide insights into overall health and nutritional balance.
What Can the Test Tell You
A urine test for Vitamin C can offer important information about how well your body is managing oxidative stress and other health insights.

If Vitamin C is detected at high levels
High levels of Vitamin C in urine indicate that the body has an adequate or excessive intake, with the excess being eliminated. While generally harmless due to its water-soluble nature, extremely high levels of Vitamin C intake can sometimes lead to gastrointestinal discomfort or increase the risk of kidney stones in susceptible individuals.
If Vitamin C is detected at low levels
Low levels of Vitamin C in urine suggest insufficient dietary intake or poor absorption. This can lead to symptoms such as fatigue, weakened immunity, slow wound healing, and, in severe cases, scurvy—a condition characterized by bleeding gums, joint pain, and skin issues. Persistently low Vitamin C levels may also contribute to oxidative stress and reduced collagen production.
Why Vitamin C Levels Matter for Your Health
Vitamin C plays a vital role in maintaining overall health, from strengthening the immune system to protecting cells from damage caused by free radicals. Abnormal levels in urine can reflect imbalances in dietary intake, poor absorption, or excessive excretion, which may signal underlying health concerns or nutritional deficiencies.
Who should consider Testing?
If you have a poor diet or malabsorption issues
Oxidative stress is often linked to lifestyle factors, and testing can help determine if your body is under strain.
If you are supplementing Vitamin C
Monitoring levels can help ensure you're not over-supplementing, which may lead to potential side effects like kidney stones.
If you experience symptoms of deficiency
Fatigue, frequent colds, or slow wound healing may indicate low Vitamin C levels that warrant testing.
If you have kidney-related concerns
Testing can help evaluate whether excess Vitamin C intake might be impacting kidney function or stone formation.
Why testing is important
Testing Vitamin C levels in urine provides critical insights into your nutritional status and overall health. It helps you determine whether your dietary intake meets your body’s needs or if supplementation adjustments are necessary. Regular monitoring can also support long-term health by preventing deficiencies or excessive intake.
Vitamin C is a cornerstone of good health, and maintaining the right balance is essential for immune support, cellular repair, and overall vitality. Regular testing can ensure your body has the optimal amount to function at its best.
