Vitamin C can potentially cause or worsen GERD symptoms in some individuals, particularly when taken in high doses or in acidic forms. The acidity of vitamin C supplements can irritate the esophagus and trigger acid reflux symptoms 1. If you experience GERD and want to take vitamin C, consider using buffered or non-acidic forms like calcium ascorbate or sodium ascorbate instead of ascorbic acid. Some key points to consider when taking vitamin C with GERD include:
- Start with lower doses (250-500mg) and gradually increase if tolerated
- Take vitamin C supplements with food rather than on an empty stomach to help minimize irritation
- Be aware that the mechanism behind this reaction is straightforward: vitamin C is naturally acidic, and introducing additional acid into an already sensitive digestive system can disrupt the balance and trigger reflux
- If you notice worsening GERD symptoms after taking vitamin C supplements, reduce your dosage or discontinue use and consult with a healthcare provider about alternative options for meeting your vitamin C needs through diet or specialized supplements 2, 3. It's also important to note that lifestyle changes, such as weight loss and smoking cessation, can be beneficial in managing GERD symptoms 2. Additionally, medication and surgery are also treatment options for GERD, and the clinical management of GERD influences the lives of many individuals and is responsible for substantial consumption of health care and societal resources 1.
