How to Use Vitamin C for Acid Reflux

Acid reflux, also known as gastroesophageal reflux disease, or GERD, describes a condition in which the contents of the small intestine or stomach repeatedly back up into the esophagus. This can cause nausea, heartburn and sore throat. Lifestyle changes and medication are typically used to treat this condition, although surgery might be necessary in some cases. Some individuals might find that vitamin C can help reduce symptoms of reflux, but this might not work for everyone. Talk to your doctor before using vitamin C for your reflux, to see if it is safe and appropriate for your situation.

Take 500 mg of vitamin C twice daily. According to, individuals with gastritis have been found to have low levels of this vitamin in their stomach juices. This might help with reflux. Check with your doctor before taking these doses to make sure it is safe for you to do so.

Consume vitamin C with meals to reduce stomach upset. If you find your stomach is still bothered by the vitamin, try taking "buffered" vitamin C.

Continue taking any medications your doctor has prescribed, or any over-the-counter medications, for your reflux unless your physician tells you otherwise. Ask your doctor whether they are safe to take with vitamin C.


Eat foods containing antioxidant vitamins, such as blueberries, tomatoes, cherries, squash and bell peppers. According to the University of Maryland Medical Center, eating foods rich in B-vitamins and calcium, drinking six to eight glasses of water a day, minimizing your red meat intake and avoiding coffee, alcohol and carbonated drinks can all help relieve symptoms of reflux.


Prior to taking vitamin C as a treatment for your reflux, ask your doctor whether it will interact with any other medications you are taking. Even though it is a natural vitamin, it can interact with drugs, including certain chemotherapy drugs, birth control pills, nitrate medications and certain pain relievers.

If you are pregnant or breastfeeding, check with your obstetrician about whether it is safe for you to take large doses of vitamin C.
