The More Antacids You Take, The More You'll Need.
Antacids kill your acid. So your body makes more. That's why you need more and more and the burn keeps coming back.
There's a different approach. Instead of killing acid, you block it from rising—while coating and healing the tissue it already damaged.
Three layers working together. That's UltraGut.

The Antacid Trap
You feel the burn. You take a Tums. It kills your acid. Burn stops.
But your stomach notices the acid is gone. It panics. Makes MORE acid to replace what you killed.
20 minutes later? More acid than before.
So you take another Tums. And another.
This is called rebound hyperacidity.
It's why you need more and more. It's why you can't stop.
PPIs do the same thing—just slower. Your doctor said "a few weeks." That was years ago. And every time you try to quit, the rebound is brutal.
Here's the problem: Any approach that KILLS or SUPPRESSES your acid triggers your body to fight back. You're stuck in a cycle that never ends.
But what if you didn't kill your acid at all?
Suppressing vs. Blocking: Why It Matters
There are two ways to deal with stomach acid. One traps you in a cycle. The other ends it.
You destroy or reduce your stomach acid. Your body detects the change. It compensates by producing more. You need higher doses. The cycle continues forever.
You don't touch your acid. You let it stay exactly where it is—doing its job. You simply put a physical barrier at the top of your stomach so acid can't splash up into your throat.
Your acid keeps working. Digesting food. Killing germs. Absorbing nutrients.
But it can't go where it hurts.
Acid stays down. You stay calm. No chemical war with your own stomach.
This is the difference between fighting your body and working with it.
The Discovery That Changed Everything
Did you know?
Americans and Japanese have the same stomachs. Same acid. Same biology. But acid reflux affects 22% of Americans and only 3.6% of Japanese.
Same bodies. Wildly different outcomes. Why?
In the 1980s, researchers in Japan noticed something strange.
American companies asked: How do we kill stomach acid?
These researchers asked a different question: What if we just keep it where it belongs?
They found the answer in something the Japanese had been eating for centuries...
brown seaweed.
When a compound in seaweed called sodium alginate meets stomach acid, something remarkable happens: it forms a floating gel barrier.
Like a lid on a pot. Acid stays underneath. Can't splash up.
They called it raft technology.
And it's been the standard heartburn approach in the UK, Europe, and Japan for over 40 years.
But the researchers knew the raft alone wasn't enough
It blocks acid from rising — but what about tissue that's already irritated?
So they combined the raft with traditional soothing botanicals:
Slippery elm + marshmallow root → to coat and protect irritated tissue
Concentrated aloe vera → to calm inflammation and support natural repair
Block. Coat. Heal. Three layers working together.
That's what UltraGut is built on.
3 Layers. One Chew. Here's the Science.
Every ingredient is clinically studied. Every layer has a job. Nothing is filler.
Within 30 seconds of hitting your stomach acid, it forms a buoyant gel 'raft' that floats on top of your stomach contents, physically blocking acid from splashing up into your esophagus.
No chemicals. No rebound.
Within seconds of swallowing, these two produce natural mucilage a slippery, protective gel that coats your throat and esophagus on contact. Think of it as a soothing blanket layered over your esophageal lining, creating a physical barrier between raw tissue and stomach acid.
Two sources of protection. One seamless shield.
Years of acid exposure leave tissue raw and inflamed. This 200× concentrated aloe vera inner leaf extract helps soothe discomfort and supports your body's natural comfort.
Not just stopping the burn, supporting recovery from damage already done.
One ingredient can't do all three.
Alginate alone blocks but doesn't protect or heal.
Herbs alone coat but don't stop acid at the source.
Aloe alone soothes but doesn't prevent new damage.
Together? The complete system.
Published Science. Not Marketing Claims.
Visible on MRI (2013)
Researchers watched the raft form in real-time. A physical barrier floating on stomach contents. You can literally see it working.
4.42× More Effective (2016)
1,107 adults. Raft technology vs. antacids. Result: 4.42 times more effective at reducing reflux episodes.
40+ Years Safe (Japan & Europe)
Millions of doses since the 1980s. No serious side effects. No dependency. No rebound.
What We Left Out (On Purpose)
Zero Aluminum
Most liquid antacids contain aluminum hydroxide. Long-term exposure is linked to bone density loss and kidney concerns. Your heartburn relief shouldn't create new problems.
Zero Calcium Carbonate
It kills acid for about 20 minutes, then your stomach overproduces to compensate
Zero Chalk or Metallic Taste
No chalky texture. No pink sludge. Lemon-berry flavor sweetened with monk fruit and stevia.
Zero Systemic Absorption
UltraGut works in your stomach and stays there. Nothing enters your bloodstream
Zero Artificial Anything
No artificial colors, flavors, or preservatives. Clean label. Plant-based. What you see on the label is what's in the chew.
Zero Dependency or Rebound
No rebound effect. No dose escalation. Use it when you need it. Stop when you don't.

"Skeptical after trying other supplements without success. But the research on their ingredients convinced me to give it a go. I now officially rely on these chews to get me through the night! 10 out of 10 forever. I also love the flavor!”
“I cannot even express how much ultragut has helped me. It has been months and months that I have suffered from acid and vomiting. I have had every scope and been to every doctor – no permanent lasting relief. I consumed 4 bottles in total and my acid and sickness have completely vanished"
“This stuff works fast and provides me relief for hours. I am happy to not be drinking that pink stuff all the time to help ease the discomfort. I can finally lay down to get a good night’s sleep without burning pain in my stomach and esophagus.”
“So let me get this straight, this is nothing short of a miracle. I have officially tried every item on the list of don’ts with acid reflux since using them, without any issue. Just within the last 7 days I have had coffee, chocolate, and pizza. WOW!”
“Does not “cling” to teeth and tongue or have a gross taste. THE BEST I TRIED SO FAR! THANK YOU!”
“Let me tell you. I have the worst heartburn, ruins every meal. But one of these babies in the morning, gives me a whole day of joyous eating. I’m good here.”
“I keep my chews next to my bed and simply pop one into my mouth and follow with a few sips of water. I like the taste, and the relief is immediate. Thank you to the people who created these!”
"Love this product. I have difficulty going to sleep due to indigestion and gas. ViVi alleviates these issues allowing me to go to sleep. It works better and quicker than other products that I have tried.”
"Nobody gets heartburn more than I do. I could drink water and suffer, it is so bad that it wakes me up at night.. I am 26. My mothers doctor recommended me this and I hopped on the bandwagon since 5 days now (I take 2 daily) and have not experienced heartburn once. It's 100% worth it”
