## Customer Reviews

### ⭐⭐⭐⭐⭐ Very Effective for Acid Reflux, Though Pricey
*by  on Reviewed in the United Kingdom 16 March 2026*

I would be lost without Gaviscon Advance Aniseed (Double Strength). There are several Gaviscon products available for different issues, but this is the one that works best for my acid reflux.The aniseed flavour is gentle on the stomach, whereas peppermint can feel a bit stimulating for me. I take it regularly and also as a top-up when my reflux symptoms flare up. The alginate forms a protective barrier that helps calm my symptoms almost immediately.My only drawback is that it is a little on the expensive side, but it is very effective.

### ⭐⭐⭐⭐⭐ Game changer!
*by  on Reviewed in the United Kingdom 10 July 2026*

This has been a game changer for me, I'm trying very hard to come off PPI's due to the effects they can have on vitamin and mineral absorption, I now take Gaviscon Advance before bed on the days I don't take PPI's and it really does help a lot. The taste isn't the best but it's only for a few seconds so I can live with that. I tend to just take a small swig from the bottle as it's so thick, I tried it in a little measuring cup and I couldn't get it out.

### ⭐⭐⭐⭐⭐ Really helps with Silent Reflux.
*by  on Reviewed in the United Kingdom 30 June 2026*

Need this for my Silent Reflux. Very happy to see it at this price (£8) will buy again.
