Refluxter for Clinicians

Give your reflux patients a high-dose alginate raft, and try it yourself, on us.

Refluxter delivers 1,000+ mg of sodium alginate per serving with calcium carbonate and sodium bicarbonate, a non-systemic, mechanical raft that floats on gastric contents to help limit reflux of acid and pepsin into the esophagus and pharynx. No acid suppression. No chalky liquid. The 1,000+ mg of sodium alginate mirrors the amount used in the European clinical studies of alginate raft therapy, in a capsule your patients can actually get in the U.S.

Why clinicians choose Refluxter

Study-level alginate dose
Over 1,000 mg of sodium alginate per serving, at or above the doses in much of the published raft-therapy literature. The amount was chosen to mirror the European clinical studies of alginate raft therapy.
Non-systemic mechanism
A physical raft barrier. It isn't absorbed and doesn't suppress gastric acid, so it doesn't interfere with digestion or the acid patients need for nutrient absorption.
pH-independent for LPR
Because it blocks reflux mechanically, the raft can help hold back both liquid and gaseous reflux regardless of acidity; relevant when pepsin drives silent-reflux symptoms.
Adherence-friendly capsule
Taste-free vegan capsules; no chalky tablet, no gel, no sugar, no aluminum. Easy to carry and to dose after meals or before bed.
Fills the U.S. availability gap
Much of the alginate evidence studied formulations not sold in the U.S. Refluxter is a high-dose alginate your patients can obtain domestically.
M.D.-formulated, made in the USA
Developed by Sarv Kannapiran, M.D., J.D., M.B.A., around the three ingredients the alginate research identifies in the most effective products.

How the raft works

1 · Forms
Contact with gastric acid releases CO₂ and sets the alginate into a light, buoyant gel within minutes.
2 · Floats
The low-density raft rises to the top of stomach contents and sits at the gastroesophageal junction as a mechanical barrier.
3 · Clears
The raft stays in the GI tract, is gradually broken down, and is excreted; not absorbed into the bloodstream.

GERD vs. LPR at a glance

Feature GERD LPR (silent reflux)
Typical symptoms Heartburn, chest discomfort, regurgitation, nausea Chronic cough, hoarseness, throat-clearing, globus, mucus
Main injurious agent Acid Pepsin (active even at higher pH)
Tissue affected Esophagus (more resilient) Larynx & pharynx (more delicate)
Time to judge response ~2 weeks of consistent use A full 8 weeks; mucosa heals gradually

Patient counseling at a glance

  • Dose & timing: 2 capsules with water after meals and/or before bed, up to 8 capsules/day. The bedtime dose, taken last, after the final food or drink, matters most for nighttime and LPR symptoms.
  • Set expectations: it's a barrier built through consistent use, not an instant antacid. Judge heartburn/GERD at about 2 weeks and LPR at a full 8 weeks.
  • Alongside existing therapy: patients often continue a morning PPI and add Refluxter after meals and at night for breakthrough and nocturnal symptoms.
  • Medication spacing: to avoid entrapment in the raft, advise spacing other oral medications and supplements 30–60 minutes before, or ~4 hours after, a Refluxter dose. Separate calcium-sensitive drugs (e.g., levothyroxine, tetracyclines, fluoroquinolones, bisphosphonates) by at least 4 hours.
  • Avoid eating right after dosing, which can disrupt a freshly formed raft.

The Clinician Handbook expands each of these into full detail, with dosing tables, safety and sodium/calcium accounting, and ready-to-say counseling scripts.

Who should not use Refluxter

Refluxter carries a product-label warning against use in patients with an esophageal stricture or swallowing disorder (a size 00 capsule and its swelling gel could lodge in a narrowed esophagus), and in patients with an ileostomy or other condition affecting intestinal transit (alginate passes through the small bowel largely intact).

Use with caution and clinician oversight in patients with severe kidney disease (account for sodium and calcium) or a known severe seaweed allergy. See the Clinician Handbook for full contraindications and cautions.
