"I’ve tried everything, for years I kept those pink bottles lined up on my counter, but they only worked for a few minutes before the burn came back. The UltraGut chews actually taste amazing and they do such a good job helping me feel calm and comfortable after meals."
"At 56 years old, I finally found a product that stopped me popping pills and taking awefuls swigs i dont even measure after every meal! I’m in disbelief, I thought I’d be stuck on PPIs forever. Thank you!!!”
“I have tried all the diet tricks and antacids but my stomach just vomits them up every single time leaving my throat raw, but since I discovered vivi not a single sour wave… NOTHING! I genuinely don’t know what I’d do without this now.”
Does food fights back after you eat or lie down?
🚫 These Aren’t “Just Annoyances”...
They're Often Warning Signs Of Unbalanced Gut Acidity
You Already Know What's Coming
That tightness after dinner. The sour taste creeping up. Lying in bed wondering if you should've skipped the tomato sauce.
You've tried to fix it with:
The Pink Bottles
The Chalky Tablets
The PPIs Your Doctor Gave you
“Natural” Home Remedies
Collecting Digestive Supplements & Probiotics
Bottom line? None of it fixes the problem. You're just managing it. Or renting relief...
You don't want a short-lived fix, or to risk side effects and dependency...
It's time to protect and strengthen your gut lining and to stop relying on solutions that leave you dependent on trading the burn for bloat.

Why Trust Vivi?
NO SOLUTION ON THE MARKET MET OUR STANDARDS...
So We Created One With Pure, Science-Backed Natural Ingredients
Aloe Vera 200:1 (Inner Leaf) – 150 mg
For cooling the burn and repairing the lining
Aloe vera has been prized for centuries for its soothing and healing properties.
UltraGut™ delivers an ultra‑concentrated 200:1 inner‑leaf extract, giving you the equivalent of a whole aloe leaf in a two tiny chews.
Real results from scientific studies:
In a 4‑week randomized trial, aloe syrup significantly cut burning, regurgitation and nausea².
Aloe’s anti‑inflammatory and wound‑healing actions help damaged tissue recover¹.
Aloe polysaccharides may reinforce the gut lining and ease inflammation¹.
Participants in the clinical trial reported no adverse events or withdrawals¹.
Sodium Alginate – 500 mg
To block sour waves at the source
Derived from seaweed, sodium alginate forms a buoyant “raft” when it meets stomach acid. This foam floats on top of your stomach contents, displacing the post‑meal acid pocket and preventing sour waves from reaching your throat⁵.
UltraGut™ uses the clinically proven dose to build a sturdy raft without added calcium or chalk.
Real results from scientific studies:
A meta‑analysis of 14 randomized trials (2,095 participants) showed alginates were 4.42× more effective at relieving symptoms than placebo or antacids⁵.
Controlled studies reported significant improvements in symptom scores and fewer nights with discomfort compared with placebo⁵.
Acts only in your stomach and isn’t absorbed into the bloodstream so it stays local and doesn’t circulate through your body. considered safe for pregnant people and children because it isn’t absorbed⁵.
Forms a buoyant foam barrier on top of stomach contents, pushing the acid pocket away from the esophagus⁵.
Slippery Elm Bark Powder – 150 mg
For a gentle shield and calm comfort
Slippery elm has a long history as a demulcent—a substance that swells into a soothing gel. When mixed with saliva, its mucilage coats the throat and esophagus, creating a protective layer that cushions inflamed tissues¹³. This natural shield has been used traditionally for hyperacidity and ulcer support, and modern in‑vitro studies suggest it can foster beneficial, barrier‑supporting bacteria ⁶.
UltraGut™ includes high‑quality powdered bark to deliver a rich source of mucilage in each chew.
Real results from scientific studies:
Slippery elm mucilage swells into a gel that coats and protects the throat and stomach lining ⁶.
Traditionally used to calm occasional hyperacidity and soothe ulcers thanks to its protective gel ⁶.
In‑vitro research shows slippery elm increases butyrate‑producing bacteria and supports a healthy microbiome ⁶.
A time‑honoured demulcent that delivers comfort without harsh additives¹³.
Marshmallow Root Extract (10:1) – 100 mg
For protective gel and gentle relief
Marshmallow root is rich in mucilage—a thick, sticky polysaccharide that becomes gelatinous when mixed with water. This gel creates a protective film over the throat and stomach lining, soothing irritation and shielding tissues from further damage⁷.
UltraGut™ supplies a 10:1 extract of marshmallow root to maximize mucilage and protective compounds in a small dose.
Real results from scientific studies:
In a survey of 822 people, marshmallow lozenges or syrup relieved irritation within 10 minutes⁷.
Its mucilage coats the throat and stomach, creating a barrier that shields tissues from irritation⁷.
Lab studies show marshmallow mucilage has anti‑inflammatory and antioxidant effects on human immune cells⁷.
Flavor & Experience
UltraGut™ tastes like lemon‑berry not medicine or toothpaste.
What makes it a smooth chew with a clean, non‑sticky finish you’ll actually enjoy?
no artificial colors, additives, salts or sugars.
- Adds a juicy berry note
- Creates a pleasant, rounded sweetness without added sugar.
- From citrus peel; gives a bright lemon aroma and clean aftertaste.
- Balances the berry profile so it doesn’t taste medicinal.
Other Ingredients: Natural Lemon & Berry Flavors, Monk Fruit Extract, Stevia Leaf Extract (Reb-A), Mannitol, Microcrystalline Cellulose, Silica, Magnesium Stearate (vegetable source).

"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”
