Sodium Alginate to Treat Non-Acid Reflux

Sodium Alginate specifically and by itself can be purchased to help treat non-acid reflux. This is in contrast to trying to obtain Gaviscon Advance which can be difficult to obtain for those living in North America. Skip the introduction for bottom line information...

Introduction

Over time, I have received a number of emails from patients regarding the best type of Gaviscon Advance they should purchase for relief of NON-acidic laryngopharyngeal reflux (LPR). The blunt answer is to get the Gaviscon Advance Suspension/Liquid made by Reckitt Benckiser which contains at least 500mg of sodium alginate in 5ml dose (1 tsp) or 1 gram in 10cc dose (2 tsps). This formula of Gaviscon Advance cannot be purchased in the United States, but instead overseas via online pharmacies located in the United Kingdom (link). Occasionally, Amazon.com does stock it.

The Gaviscon (without the "advance") sold in the United States is manufactured and distributed by GlaxoSmithKline (GSK) and not Reckitt Benckiser. The US brand of Gaviscon by GSK contains less of the key ingredient sodium alginate which helps with NON-acidic reflux. Alginate is a natural product derived from seaweed. The alginate reacts with the acid in the stomach to produce a "raft" barrier that acts as a physical block to reflux. It is the only non-surgical treatment that can physically prevent reflux disease regardless of whether it is acidic or not. Alginates work rapidly, are long lasting, inexpensive, and have no known side-effects.

Sodium Alginate

But because Gaviscon Advance is so hard to obtain in the United States, one of my patients suggested why not take just the sodium alginate and forget about the gaviscon? After all, it's the sodium alginate that's the key ingredient that is thought to help.

Great idea!

Even better is the fact that sodium alginate is easier to find and obtain.

If possible, I would stick to roughly the same amount of sodium alginate that would be ingested if Gaviscon Advance itself was taken:

500mg to 1000mg of sodium alginate after every meal and at bedtime.

Here's one product I found on Amazon.com.

DISCLAIMER!!! Please be aware that I can NOT vouch for overall effectiveness given these "supplements" have NOT been scientifically tested for clinical effectiveness nor is regulated by the FDA even though the same active ingredient sodium alginate is present. Use at your own risk!!!
