Is It Beneficial To Take Atrantil Even If You Do Not Have Digestive Symptoms?

Yes, Atrantil has a super high antioxidant count and is full of beneficial polyphenols. Taking Atrantil on a daily basis is ideal for maintaining overall digestive protection and support.

How Long Does It Take To Feel Results From Atrantíl?

People suffering from occasional symptoms have seen results in a couple of hours after taking one dose of two capsules. We recommend that you continue to take Atrantíl up to three times a day until you achieve significant relief. With this schedule, you can typically expect to see relief in seven to 10 days. However, for some sufferers, it may take 20 to 30 days to experience significant relief.* *Individual results may vary

What Are The Side Effects Of atrantil?

The side effect profile for Atrantíl has been very minimal. A small amount of customers have seen some mild abdominal discomfort when taken on an empty stomach. Those symptoms are resolved when taken with food. Also, for some, if their bacterial load is high they can experience temporary symptoms such as muscle ache, foggy head, headache, etc. This is believed to be a sign that Atrantíl is working and the reaction is related to toxins from the bacteria causing a mild reaction itself.

It is ok to continue taking other supplements and digestive enzymes while taking Atrantil. However, we do not recommend taking probiotics while taking Atrantil, unless they are spore-based. The reason we do not recommend other kinds of probiotics is that Atrantil works to get rid of the overgrowth of bacteria in the small bowel, which causes adverse symptoms. By adding in more bacteria through probiotics, you are adding more fuel to the fire by putting more bacteria in the area we are trying to get rid of it.  

Atrantil has been clinically tested and proven. For those suffering from bloating, Atrantil was proven to be over 80% effective in both double-blind and open-label trials.


In a double-blind clinical study of patients suffering from bloating, constipation, and abdominal discomfort, Atrantíl proved to be more than 88 percent effective in relieving symptoms.


The open-label study targeted the toughest-to-treat patients to illustrate the efficacy of Atrantíl. 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 Atrantíl to control their bloating, constipation, and abdominal discomfort.

Made up of three polyphenols- Quebracho Colorado, Horse Chestnut, and Peppermint- Atrantil is backed by science and clinically proven.

Can I Take Probiotics/Other Supplements While Taking Atrantil?

Peppermint –

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 that 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).

Quebracho –

Horse Chestnut –

A natural inhibitor to the enzyme that allows methane to be produced, this extract enters the archaebacteria cell through the disrupted cell wall and shuts down the methane-producing mechanism.

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.
