How Atrantil Works

For all people, Atrantil can provide daily digestive support and balance. But for millions that have bloating and abdominal discomfort alone or accompanied by constipation, diarrhea or both make life miserable.

New research shows that the problems start with methane producing bacteria. Left untreated, these out-of-place bacteria feed off the foods you eat and create methane gas that leaves you bloated and uncomfortable.

Atrantil breaks the cycle naturally — and gets you and your digestion back on track.

The Real Problem

Methane producing archaea/bacteria living in the small bowel.


Archaebacteria feed on free hydrogen to produce methane.


A natural antispasmodic, Atrantil uses the whole leaf extract (not just oil) to briefly relax the small bowel which in turn allows Quebracho and Horse Chestnut work to more efficiently.


A natural and very complex polyphenol which soaks up the hydrogen (the fuel needed for methane production), and also binds to and disrupts the cell wall of the archaebacteria (this weakens and stresses the methane producer).

Horse Chestnut

Used for hundreds of years in medicine for a variety of conditions. From improving leg swelling to gastrointestinal problems, the use of horse chestnut as a supplement has long been documented and more recently researched.

All three of the natural ingredients in Atrantil are polyphenols. After their work is done in the small bowel, they move to the colon where they are naturally cleaved and broken down into beneficial compounds, making them great prebiotics.

ATRANTIL Reduces Unwanted Bacteria

Reducing methane-producing bacteria returns the upper GI tract to its normal nearly sterile condition and helps the digestive system to work the way it should.

Results Proven in Clinical Research

Northwestern Feinberg School of Medicine

Northwestern University Feinberg School of Medicine Study

This study demonstrated the most ideal test for any over the counter solution regarding health issues such as bloating or associated gastrointestinal methane problems. First, the results demonstrated that 56% of all participants experienced adequate relief. Those results were measured against SEVEN categories of suffering. Second, this was a 100% independent, major university medical school test constructed without bias. Third, essentially there were no exclusionary criteria for participants. These are serious parameters for any solution to meet a challenge and Atrantil more than met expectations. The integrity of the design was trusted to a worldwide recognized leader in gastroenterology, the Principal Investigator, Darren Brenner, MD, FACG, AGAF, RFF. Dr. Brenner is a professor of medicine and surgery, an IDP Foundation Research Scholar, and the director of the Northwestern University Neurophysiology Program.

None of KBS Research, LLC and all associated partners had any influence, monetary or otherwise, regarding the study design, product acquisition, or analysis of results.

88% of Patients Found Relief

Double-Blind Study

In a double-blind clinical study of patients suffering from bloating, constipation and abdominal discomfort, Atrantil proved to be more than 88 percent effective in relieving symptoms. The results of the study were published in the Journal of Gastroenterology and Hepatology Research – September 21, 2015 pp. 1762-1767.

80% Effective

Open-Label Study

The open-label study targeted the toughest-to-treat patients to illustrate the efficacy of Atrantil. Before beginning the study, patients qualified to participate only after failing to find relief from at least four other therapies. The trial showed that 80 percent of patients found relief after using Atrantil to control their bloating, constipation and abdominal discomfort. The results of the study were published in the World Journal of Gastrointestinal Pharmacology and Therapeutics – August 6, 2016 pp. 463-468.
