As your digestive system begins to rebalance, many people notice:

  • Less bloating and abdominal pressure
  • Reduced trapped gas
  • Less heartburn and post-meal discomfort
  • More comfortable digestion
  • More predictable digestive patterns
WHAT ATRANTIL SUPPORTS: GAS, BLOATING & MICROBIAL BALANCE

Atrantil is a daily supplement for gas and bloating, not an anti-bloat pill you reach for after the discomfort starts. Here is what it supports:

  • Methane-associated bloating
  • Gas pressure and abdominal distention
  • Sluggish digestion and trapped gas
  • Change in bowel habits, like constipation or diarrhea
  • Microbiome support

Clinically studied. Polyphenol-powered. Gastroenterologist developed.

WHAT TO EXPECT

Atrantil was designed to help calm the cycle behind bloating and digestive pressure.

Unlike an anti-bloat pill or a debloat supplement taken after a heavy meal, it works on the gut environment producing the gas in the first place — which is why the timeline matters more than the first dose.

As the gut environment begins to shift, many people notice:

  • less gas and bloating after meals
  • reduced pressure and fullness
  • improved digestion
  • more predictable bowel movements

This is not an immediate fix; this is a process of resetting your gut.

Atrantil works by eliminating gas-producing bacteria and supporting your microbiome.

Everyone’s gut responds differently. You may notice changes quickly, or your relief may build more gradually over several weeks as your gut environment continues to shift.

The key is commitment and consistency.

THE 30-DAY Re:set

The 30-Day Re:set is Atrantil’s structured approach to helping calm bloating, pressure, and digestive imbalance at the source. Most natural supplements for bloating are taken indefinitely with no plan attached. The Re:set is a defined protocol with a loading phase and a maintenance phase, which is what separates it from simply adding one more daily capsule.

For the first 30 days:

  • Take 2 capsules, 3 times daily with meals
  • Most people require 2 bottles during this phase

As the gut environment begins to shift, many people might notice:

  • less pressure after meals
  • reduced bloating
  • less trapped gas
  • and more predictable digestion.

Weeks 1–2
Digestive pressure and gas buildup often begin to calm.

Weeks 3–4
Digestive patterns may start feeling more stable and consistent.

Beyond 30 Days
Many people transition into a maintenance phase focused on long-term digestive support and reducing flare-ups.

*Please note: If your microbiome is off, you may feel worse before you feel better. This is a good sign; it means your microbiome is shifting. Stick with it!

Ingredients

THE THREE POLYPHENOLS INSIDE ATRANTIL

Three ingredients. One coordinated mechanism.

Peppermint Leaf
Supports digestive flow and smooth muscle relaxation within the gut. Peppermint helps calm spasms and supports more comfortable movement through the digestive tract. But more importantly, it allows the other ingredients to work more effectively.

Quebracho Colorado
It is one of the largest, most stable polyphenols that can absorb hydrogen (the fuel that the methane-producing microbes rely on). In addition, it has a natural defence against the type of organism (Archaea) that produces methane. This is how it reduces bloating and gas buildup and why it is so unique and effective.

Horse Chestnut
Contains naturally occurring saponins that eliminate hydrogen-producing bacteria and block the enzyme that produces methane.

These three polyphenols work synergistically by addressing different parts of the bloating cycle:

  • fermentation
  • methane production
  • digestive flow
  • and trapped gas.

Not by temporarily masking symptoms, but by supporting the gut environment itself. That places Atrantil in a different category from probiotics, digestive enzymes, and simethicone gas relief supplements: it is a polyphenol supplement working upstream of the fermentation that creates the gas, rather than on the gas after it forms.

POLYPHENOL SCIENCE

Atrantil is built on plant polyphenols selected for their behavior in the digestive system.

Unlike many compounds that are absorbed quickly, these polyphenols continue to work in the gut, where fermentation, gas production, and digestive imbalance often begin.

This is also why most natural remedies for bloating only go so far. Peppermint tea, digestive bitters, activated charcoal, and simethicone gas pills all act on gas that has already formed. None of them reach the microbial fermentation producing it, which is why the relief tends to last about as long as the dose does.

Research suggests these polyphenols may help support:

  • microbial balance
  • digestive movement
  • gut barrier integrity
  • and a healthier gut environment over time.

Atrantil’s three polyphenols were selected specifically for their ability to work together against gas-producing bacteria to relieve bloating, gas pressure, and irregular bowel movements.

Bloating Isn’t the Problem.
It’s the Signal.

Atrantil supports digestive balance by targeting the underlying processes that contribute to gas, bloating, and abdominal discomfort.

The Science,
Explained

Dr. Brown explains the mechanisms behind bloating, reflux, and gut health, and how each formula is built to address them.

Atrantil Targets the Root Mechanisms Behind Gas + Bloating

Gas and Bloating Are Not Random.
They’re Driven by What’s Happening in Your Gut

When microbes break down food too early in the small intestine, gas forms and creates pressure. That pressure leads to bloating, discomfort, and the feeling that your gut is not working properly. Atrantil targets the microbes behind this process, helping reduce gas at the source so your digestion can feel more consistent.

Three Targeted Polyphenol Ingredients. One Gut-Focused Formula.

Atrantil is powered by polyphenols, plant compounds that interact directly with your gut. Rather than masking symptoms, these compounds help regulate microbial activity and reduce excess fermentation, supporting a more balanced and functional digestive system.

30-DAY RE:SET FOR BLOATING RELIEF

If Bloating Has Been Building For Months Or Years, Give Your Gut More Than A Day To Respond.

Atrantil is designed to support the fermentation process behind gas and bloating. Because that process takes time to calm, consistent use over 30 days is recommended.

Most people use two bottles to see a significant change.

Atrantil
(Microbial Gas Support)

Targets methane-associated microbial activity in the small intestine, helping address one of the underlying contributors to bloating and abdominal pressure.

OTC Gas Remedies
(Symptom Relief)

Break up existing gas bubbles to reduce discomfort temporarily but do not influence the microbes that produce gas.

Digestive Enzymes
(Food Digestion Support)

Assist with the breakdown of certain foods but do not address microbial gas production associated with bloating.

Probiotics
(Microbial Support)

Add beneficial bacteria to the gut but do not directly target gas-producing microbes or fermentation in the small intestine.
