Understanding Gaviscon's Mechanisms
Gaviscon uses a unique dual-action approach to combat acid reflux and heartburn. Unlike simple antacids that only neutralize stomach acid, Gaviscon contains sodium alginate, a compound derived from seaweed. When it comes into contact with stomach acid, the alginate forms a gel-like layer, known as a 'raft,' which floats on top of the stomach's contents. This mechanical barrier physically prevents stomach acid from splashing back up into the esophagus, providing rapid and long-lasting relief from the burning sensation.
Comparing Gaviscon Formulations
Gaviscon Original
- Action: Primarily creates an alginate raft to block acid reflux.
- Best For: Fast relief of occasional or mild heartburn and indigestion.
- Key Features: Classic formula for standard symptoms.
Gaviscon Double Action
- Action: Combines the alginate raft with an antacid component (calcium carbonate and sodium bicarbonate). This provides two-pronged relief: the antacid neutralizes excess stomach acid for immediate comfort, while the raft creates a physical barrier to prevent reflux.
- Best For: Comprehensive relief from both heartburn and indigestion. A study showed its liquid form is more effective than an antacid alone at controlling post-meal esophageal acid exposure.
- Key Features: Offers both antacid and alginate benefits.
Gaviscon Advance
- Action: This extra-strength formula contains a higher concentration of sodium alginate than Gaviscon Original. This creates a more robust and resilient protective raft that provides longer-lasting relief, sometimes up to four hours.
- Best For: More persistent or severe acid reflux symptoms, including silent reflux (LPR). It is also the recommended choice for pregnant women due to its lower sodium content.
- Key Features: Extra-strength alginate, lower sodium, and longer-lasting effect.
Liquid vs. Tablets: Which Format to Choose?
Both liquid suspensions and chewable tablets offer effective relief, but they differ slightly in performance and convenience.
-
Liquids:
- Onset: Generally considered to work faster than tablets.
- Barrier: The liquid formulation is readily available to form the protective raft over stomach contents.
- Usage: Requires shaking the bottle well before use.
- Ideal for: Those seeking the quickest possible relief from a heartburn flare-up.
-
Tablets:
- Convenience: Easy to carry and take on the go without the need for a measuring spoon.
- Absorption: Must be chewed thoroughly before swallowing to ensure proper function.
- Usage: Often require a full glass of water after chewing to wash the medication down.
- Ideal for: Maintaining symptom management when away from home or for convenience.

| Feature | Gaviscon Original | Gaviscon Double Action | Gaviscon Advance |
|---|---|---|---|
| Primary Action | Alginate Raft | Alginate Raft + Antacid | Extra-Strength Alginate Raft |
| Indicated For | Occasional/Mild Heartburn | Heartburn & Indigestion | Severe/Persistent Reflux |
| Speed of Relief | Fast | Very Fast | Fast, but longer lasting |
| Duration of Effect | Standard | Up to twice as long as antacids | Up to 4 hours |
| Sodium Content | Standard | Standard | Lower |
| Pregnancy Use | Yes, but Advance may be preferred | Yes | Recommended due to lower sodium |
| Best for LPR | Less ideal | Effective | Highly effective |
Conclusion: Making the Right Choice
Determining which form of Gaviscon is most effective depends on the nature and severity of your symptoms. For mild, standard heartburn, the Original formula offers a reliable solution with its protective alginate barrier. If you experience both heartburn and indigestion, the dual-action approach of Gaviscon Double Action, with its added antacid, provides more comprehensive relief. For more severe, persistent, or nocturnal reflux—including laryngopharyngeal reflux (LPR)—Gaviscon Advance is the superior choice, thanks to its more resilient alginate raft and lower sodium content. Ultimately, discussing your symptoms with a pharmacist or doctor can help confirm the best option for your individual health needs.
What to do next
- For mild, occasional symptoms: Start with Gaviscon Original.
- For combined heartburn and indigestion: Choose Gaviscon Double Action for comprehensive relief.
- For severe, persistent, or silent reflux: Opt for Gaviscon Advance for a stronger, longer-lasting barrier.
- When pregnant: Gaviscon Advance is recommended due to its lower sodium content.
- For fast relief: Prefer the liquid formulations, as they tend to work quicker.
- For convenience: Chewable tablets are a good portable option.
