Gaviscon Heartburn and Indigestion Relief

Gaviscon is a trusted and clinically proven treatment for heartburn, acid reflux and indigestion. Customers looking to buy Gaviscon online typically want fast, soothing relief that neutralises stomach acid and forms a protective barrier to stop reflux. Gaviscon neutralises acid, Gaviscon protects the oesophagus and Gaviscon relieves heartburn. The Welzo Gaviscon collection includes liquids, chewable tablets and double-action formulas designed for rapid and long-lasting symptom control.

What is Gaviscon?

Gaviscon is a leading antacid and alginate-based treatment used for the relief of heartburn, acid reflux and indigestion. Unlike standard antacids that only neutralise acid, Gaviscon forms a protective raft on top of stomach contents that prevents reflux into the oesophagus. This dual action makes it one of the most widely recommended OTC treatments for symptoms triggered by spicy food, large meals, pregnancy, stress or late-night eating. People managing broader digestive health concerns often explore additional support from our gut health collection.

Why is Gaviscon Important?

Heartburn and acid reflux are extremely common, affecting millions of adults in the UK. Symptoms can impact sleep, diet choices, productivity and overall quality of life. Gaviscon provides rapid symptom control and reduces irritation caused by acid reaching the throat. Users with persistent digestive concerns often pair Gaviscon with complementary products from our stomach & bowel relief category for a broader approach to digestive comfort.

How to Use Gaviscon

Liquid formulas: Take 10–20 ml after meals and at bedtime.
Chewable tablets: Chew thoroughly and swallow after meals for relief.
Do not lie flat immediately after use: Allow the raft to form effectively.
Use regularly for ongoing symptoms: Daily use is common for people with frequent reflux.

If digestive discomfort is related to dehydration, illness or travel, some customers also consider rehydration treatments to support overall digestive balance.

Statistics, Research, Expert Information and Quotes

Up to 40% of adults experience heartburn at least once a month, with many reporting symptoms linked to evening meals, coffee, alcohol and stress. Clinical studies show that alginate-based reflux treatments can form a floating barrier that significantly reduces acid exposure to the oesophagus and delivers sustained relief compared with antacids alone.

“Alginate-based treatments like Gaviscon are highly effective for heartburn because they create a protective barrier that prevents acid from rising. This makes them especially useful for people who experience reflux after meals or at night.”
— Dr Sameer Nakedar, MBBS, Clinical Lead at Welzo
