Merevia Gut Barrier Support is a daily capsule made for people whose reflux keeps coming back no matter what they try. Instead of only neutralizing acid, it forms a floating alginate raft that caps the acid pocket at the top of the stomach, then supports the gut lining and motility underneath. Two capsules after your largest meal, 60 capsules per bottle.
If antacids buy you half an hour, if you still sleep propped on pillows, if dinner has turned into a calculation, the problem usually isn't too much acid. It's a valve that isn't closing and an unbuffered pocket of acid sitting at the top of your stomach. Merevia is built around that mechanical pathway rather than the smell of the symptom.
- Forms a raft that helps cap the acid pocket
- Blocks reflux mechanically without suppressing acid
- Supports repair of the gut lining
- Supports gastric motility to ease upward pressure
- No PPI dependency and no rebound when you stop

A NOTE FROM OUR FORMULATOR
Dr. Sarah Mitchell
MD · 18 Years of Experience
I kept meeting people who were doing everything right and still couldn't get through the night. They had cut the foods, stacked the pillows, and lived on antacids, and the reflux kept coming back. The reason is usually mechanical: the valve isn't closing and acid pools at the top of the stomach. We developed Merevia with my co-formulator around that pocket. The alginate raft caps it, zinc-L-carnosine and DGL support the lining, and ginger helps things move through. Every dose is on the label. Give it a few weeks. This works on the cause, and the cause doesn't turn around overnight.
Real People, Real Relief
See what customers say about Merevia Gut Barrier Support
-
★★★★★"The 3am wake-ups stopped."
Waking up with acid in my throat was the worst part of all of it. It has become rare instead of nightly, and my sleep is finally holding together.
Nighttime Root Cause -
★★★★★"Dinner stopped being a gamble."
Eating out used to mean deciding what it would cost me that night. That anxiety is mostly gone. I take two after my biggest meal and get on with my evening.
After Meals Less Anxiety -
★★★★★"I threw out the wedge pillow."
I slept propped up for three years because lying flat meant waking up choking. Around week two I tried flat again and got through the whole night. The pillow tower is gone.
Nighttime Reflux Sleep Flat -
★★★★★"Morning coffee is back."
I had basically given up my one cup because the burn wasn't worth it. After a few weeks I can drink it again without paying for it all morning.
Morning Coffee Confidence -
★★★★★"Reaching for antacids far less."
I used to keep a roll in every jacket and every drawer. These days I forget where they are. My after-dinner burning has settled down a lot.
Fewer Antacids Everyday Use -
★★★★★"Everything is on the label."
I'm on daily medication so I read ingredient panels properly. No proprietary blend, every dose listed. My chest and throat feel much calmer after meals.

WHY NOTHING HAS WORKED
It isn't that you haven't tried hard enough. Most reflux routines act on the acid itself, not on the mechanical pathway that lets it keep coming back up.
-
Antacids (Tums, Rolaids)
Neutralize acid for about half an hour. The valve is still open, so the acid comes right back.
-
PPIs (Prilosec, Nexium)
Shut down acid production. Stop taking them and the reflux often returns worse than before.
-
Diet Changes
Cutting triggers can take the edge off, but acid still escapes through a valve that isn't closing.
-
Wedge Pillows
Gravity buys you a better night. It doesn't seal the pocket of acid at the top of your stomach.
-
Chewables At 3am
A quick fix that fades by morning, and the same pattern repeats the next night.
Merevia Alginate Raft + Repair System
Forms a floating raft that caps the acid pocket, then supports the gut lining and motility so reflux is blocked at the source instead of masked.
WHAT'S INSIDE
No proprietary blends. No hidden dosages.
Every active named. Every dose on the label.
Every active named. Every dose on the label.
Phase 1: Shield
Calcium Carbonate — 150 mg
Strengthens the raft structure and helps neutralize acid on contact for support you can feel early.
Phase 1: Shield
Sodium Bicarbonate — 30 mg
Generates the micro-bubbles that make the raft buoyant, lifting it to the top of the stomach where the acid pocket sits.
Phase 2: Repair
Zinc-L-Carnosine — 37.5 mg
Used in Japan for over 20 years for stomach lining support. Binds to tissue and supports repair of the gut lining at the cellular level.
Phase 2: Repair
DGL Licorice — 80 mg
Deglycyrrhizinated licorice, studied for supporting the body's own protective mucus layer that acid suppression can thin over time.
Phase 3: Calm
Ginger Extract — 40 mg
Supports gastric motility so food moves through faster instead of sitting and pushing acid upward. One of the most studied natural anti-nausea botanicals.
ALGINATE RAFT
Cap The Acid Pocket Before It Refluxes
The alginate raft reacts with your own stomach acid to form a floating barrier over the unbuffered pocket that refluxes through a weak valve after every meal. It works mechanically, so your body keeps the acid it needs to digest.

Merevia Is Right For You If...
-
The burning comes back the moment your antacids wear off.
-
You sleep propped on pillows or a wedge just to get through the night.
-
You wake up coughing, or with acid in your throat, around 3am.
-
Coffee, dinner, or a favorite meal has turned into a calculation instead of a choice.
-
You have been on a PPI for years and you would rather not stay on it forever.
-
You want the valve and the lining supported, not just the acid neutralized for half an hour.
WHAT TO EXPECT
Everyone is different. Here is the kind of progression Merevia is designed to support.
Days 1-3
The raft mechanism goes to work quickly after dosing. Burning after meals may start to feel calmer as the barrier support kicks in.
Weeks 1-2
Nighttime discomfort may ease as you build a consistent after-meal routine. Many people start sleeping flatter.
Weeks 3-4
Gut-lining support becomes the focus. Bloating and pressure may feel less intrusive day to day.
Months 2-3
Fewer food calculations, calmer digestion, and more confidence at the dinner table and at night.
Simple, Effective, Trusted
A capsule is easy to like on week one. We wanted to know what people say once they have lived with it for a while.
91%
report fewer nighttime flare-ups than they had before.
88%
say they sleep flatter without stacking pillows or a wedge.
85%
reach for antacids far less often through the day.
79%
say the relief held without a rebound when things settled.

Neutralizing Acid Isn't Sealing The Valve
Antacids and acid blockers are chemical approaches. The alginate phase is mechanical: it forms a floating raft that helps cap the acid pocket before it can move upward, while your body keeps producing the acid it needs.
3
Three phases working together — shield, repair, calm — instead of one chemical that only masks the burn.
0
Zero acid suppression. The raft caps the acid pocket physically, so your stomach keeps the acid it needs for digestion.

You got questions, we got answers
Everything you need to know about the formula, the routine, and the guarantee.
Antacids mainly neutralize acid for a short window. Merevia uses sodium alginate to help form a physical raft over the acid pocket, then adds zinc-L-carnosine, DGL, and ginger for gut-lining and motility support. It is built to work on the pathway, not just the burn.
PPIs reduce how much acid you make. Merevia does not suppress acid at all. It is designed to help block reflux mechanically while your normal digestion keeps working, which is why there is no rebound when you stop.
Take 2 capsules daily after your largest meal, or as directed by your healthcare provider. For best results, take it consistently. The raft works after each dose, while the lining and motility support build over several weeks.
Each bottle contains 60 capsules, a 30-day supply at two per day.
The raft works mechanically after dosing, so many people feel calmer after meals early on. The gut-lining and motility support are cumulative and tend to build over the first few weeks of consistent use.
Ask your healthcare provider before combining any supplement with prescription medication, especially if you are pregnant, nursing, or taking PPIs, blood thinners, or diabetes medication.
Do not stop a PPI abruptly. Many customers taper with their doctor while using Merevia for support. Any changes to prescription medication should be made with your healthcare provider.
Please check with your healthcare provider first. We would rather you confirm it is right for your situation than guess.
Yes. Merevia uses vegetarian capsules and is made without gluten, GMOs, or artificial colors.
It works differently from an antacid and is designed to sit alongside your normal routine rather than replace everything on day one. Many people find they reach for antacids far less as the weeks go on.
Then you get your money back. Every bottle is covered by a 60-day money-back guarantee. If it is not right for you, contact support and we will handle the refund.
