Why it might work
Sodium alginate reacts with stomach acid to form a floating gel raft on the stomach contents, so that what refluxes is gel rather than acid, and the raft helps keep contents down. That is why it is taken after meals and at bedtime. RefluxRaft adds ginger, for nausea, and DGL, a licorice extract with a mucosal-protection rationale, to the alginate base.
What the research supports
Class-level evidence. A 2017 systematic review and meta-analysis of 14 randomized trials in 2,095 people found alginate-based formulations relieved reflux symptoms better than placebo or plain antacids (odds ratio 4.42). Those trials used products declaring sodium alginate at 500 to 1,000 mg a dose. RefluxRaft declares organic sodium alginate as its first ingredient; no trial of the product was found.
What the label discloses
The listed ingredients are organic sodium alginate, ginger root and deglycyrrhizinated licorice in a lemon-ginger gel, sugar-free, 28 mg of sodium per serving, 60 servings per tube. The alginate amount is not on the listing. The brand states the formula is doctor-founded and made from natural ingredients. No third-party testing certificate is published.
Who this tends to suit
We match this product to people reporting heartburn or reflux and general abdominal discomfort. It fits someone whose priority is day-to-day comfort or handling meals. Whether it is the best fit for you depends on the rest of your answers — what you have already tried, what format you will take, and anything that has to be ruled out.
Where it may not fit
The label supports gluten-free and no added sweeteners. A liquid only works if you will take it as often as the label directs.
Side effects and what to be aware of
Reviews split sharply between relief and nothing, and many find the gel thin and hard to swallow, with some reporting nausea. The alginate amount per serving is stated on the pack but not the listing, and no trial has tested this product; the class evidence comes from European Gaviscon formulas. At $32.99 for 60 servings, two doses a day is about $1.10.
