The throat-clearing. The 3am cough. The lump that won't go away.
If antacids and PPIs never quite fixed it, that's because silent reflux (LPR) isn't ordinary heartburn — and it needs a different kind of barrier.

Does this sound like your reflux?
LPR (laryngopharyngeal reflux) often shows up in your throat and voice — not as classic heartburn. People are surprised reflux is the cause.
- ✓ A constant need to clear your throat
- ✓ The feeling of a lump in your throat (globus)
- ✓ Hoarseness or a voice that tires easily
- ✓ A nagging, dry cough — often worse at night
- ✓ Post-nasal drip that won't clear
- ✓ Trouble swallowing or a scratchy throat
If you checked even two of these, a raft-forming alginate is exactly the mechanism designed for it.
Why antacids and PPIs miss silent reflux
Antacids only neutralize acid that's already escaped. PPIs reduce acid production but take days to kick in and aren't meant for long-term use. Neither stops reflux from physically rising into your throat — which is the whole problem in LPR.
How Refluxter works
It forms a raft, not a chemical
On contact with stomach acid, the seaweed-derived sodium alginate forms a low-density gel raft that floats on top of your stomach contents.
It caps the “acid pocket”
That raft sits over the pool of acid that forms after eating — the source of post-meal reflux — and physically blocks it from rising toward your esophagus and throat.
Fast and non-systemic
It works within 10 minutes and lasts up to 4 hours. Because it acts physically rather than being absorbed into your bloodstream, it can be taken long-term.
Built on clinical research — including LPR specifically
In a study of 100 outpatients with laryngopharyngeal reflux, alginate therapy produced a statistically significant reduction in voice issues, swallowing difficulty, and chronic cough over 60 days.
Ciprandi et al., 2021 — J. Biol. Regul. Homeost. AgentsA systematic review found alginate therapy worked within an hour and was not inferior to a leading PPI for relieving moderate, episodic reflux symptoms.

Questions people ask
How is this different from Tums or a PPI?
Antacids neutralize acid that already escaped; PPIs suppress acid production over days and aren't intended for indefinite use. Refluxter forms a physical raft that blocks reflux from rising in the first place — and works within minutes.
Can I take it long-term?
Because it acts physically rather than being absorbed systemically, it's designed to be taken long-term without the concerns associated with chronic acid-suppressing drugs.
How fast does it work?
The raft forms within about 10 minutes of taking it, with relief lasting up to 4 hours — making it well suited to after meals and before bed.
Does it help silent reflux (LPR), not just heartburn?
Yes — LPR is exactly the use case here. Clinical research in LPR patients showed significant reductions in throat-clearing, hoarseness, and chronic cough with alginate therapy.
Quiet the throat-clearing. Sleep through the night.
