Gastro-oesophageal reflux disease — GERD — affects a significant share of adults, and diet is central to how it behaves day to day.
The Acid Connection
Reflux occurs when stomach acid moves upward into the oesophagus. Research into alkaline water has examined whether raising pH can help neutralise pepsin, the enzyme implicated in reflux irritation.
Findings So Far
Studies have observed that water at a higher pH can deactivate pepsin in laboratory conditions, suggesting a supportive role alongside medical treatment — not a replacement for it.
A Sensible Approach
If you experience persistent reflux, speak to a physician. Alongside that, choosing a naturally alkaline, mineral-balanced water is a small change that costs nothing to try.
