Gaviscon vs. Gaviscon Advance — What's the Difference?

Difference Between Gaviscon and Gaviscon Advance


Key Differences

Gaviscon is a well-known antacid used to relieve symptoms of heartburn and indigestion. It works by neutralizing stomach acid and forming a protective barrier. Gaviscon Advance, on the other hand, contains a higher concentration of sodium alginate, which enhances its efficacy in treating reflux symptoms.
The formulation of Gaviscon includes ingredients like aluminum hydroxide and magnesium carbonate, which help reduce stomach acidity. In contrast, Gaviscon Advance focuses more on the use of alginate, providing a stronger and longer-lasting barrier against stomach acid.
Gaviscon is often recommended for mild to moderate symptoms of acid reflux and indigestion. Gaviscon Advance, with its higher alginate content, is better suited for more severe cases, offering prolonged relief.
The availability of Gaviscon varies, with some versions containing different active ingredients in various regions. Gaviscon Advance, however, consistently contains a higher dose of alginate across its versions, making it a preferred choice for more persistent symptoms.
While both products are used to treat similar conditions, Gaviscon Advance's enhanced formula makes it a more potent option for individuals needing stronger or longer-lasting symptom control.
