The combination works synergistically to neutralize stomach acid, form a protective barrier, and prevent acid from rising into the esophagus.

Sodium alginate, a naturally derived compound from seaweed, forms a viscous gel that floats on top of the stomach contents. This gel acts as a physical barrier between stomach acid and the esophagus, thereby preventing reflux and the burning sensation of heartburn.

Sodium bicarbonate is a fast-acting antacid that neutralizes excess stomach acid, offering immediate relief from acidity and discomfort.

Calcium carbonate not only neutralizes acid but also provides a sustained buffering effect, helping maintain stomach pH and reducing further irritation. It additionally offers a mild source of elemental calcium, which supports bone health.

This combination is widely used to manage GERD symptoms, acid indigestion, gastric reflux, and post-meal acidity. It is safe for long-term use under medical supervision and suitable for adults and elderly patients who suffer from chronic acidity or reflux-related discomfort.
