Atrantil Review - 14 Things You Need to Know

Atrantil is relatively new, but it’s been making some headway in the industry. It was developed by a Gastroenterologist and claims to relieve bloating, abdominal discomfort and changes in bowel habit.

With a small ingredient list, our research team wanted to better understand the benefits of the ingredients, potential side effects of the ingredients and the research supporting the claims. Then, we gathered the facts and data to give you the bottom line.

What is Atrantil?

Atrantil is a dietary supplement designed to provide daily digestive support and balance. It claims to help you reduce bloating, abdominal discomfort, and unwanted changes in bowel habits.

This supplement says it uses natural botanicals and is not a probiotic or digestive enzyme supplement.

How Did Atrantil Start?

Dr. Ken Brown is a busy gastroenterologist in the Dallas area. In 2008, he participated in clinical trials for a new drug for IBS and the drug barely performed better than placebo in the tests while also causing a lot of adverse side effects.

He decided he wanted something better for his patients. In 2012, he formed KBS research to explore natural solutions to provide relief for uncomfortable symptoms created in the gut.

They created Atrantil as a result of that research and testing.


Atrantil Claims

Atrantil claims to be able to help treat bloating, constipation, diarrhea, and general stomach discomfort.

It claims to be able to work within a couple of hours of experiencing symptoms, and it claims that when taken regularly it can help keep those symptoms that bad all the time.

It works by preventing methane-producing bacteria from feeding on the food you eat then leaving you bloated and uncomfortable.

Atrantil ingredients


Atrantil Ingredients

  • Peppermint Leaf
  • Quebracho extract
  • Horse Chestnut


Peppermint is a well-known plant both the leaf and oil are used as medicine.

Peppermint is used to treat the common cold, cough, inflammation of the mouth and throat, sinus infections and respiratory infections.

You can also use it to treat a variety of digestive problems including nausea, vomiting, morning sickness, heartburn, IBS, cramps of the upper gastrointestinal tract and bile ducts, upset stomach, diarrhea, bacterial overgrowth of the small intestine, and gas.

Peppermint oil can be applied to the skin for headache, muscle pain, nerve pain, toothache, inflammation of the mouth, various joint conditions, allergic rash, bacterial and viral infections and relaxing the colon during barium enemas.

It’s worth noting that in 1990 the FDA banned the sale of peppermint oil as an over the counter drug for use as a digestive aid because its effectiveness had not been proven.

Today it is sold as a dietary supplement, so the FDA does not have to prove it’s effective for it to be marketed. Peppermint oil seems to work by reducing spasms in the digestive tract. It may also help slow memory decline in older adults.Atrantil ingredients peppermint

Both peppermint and peppermint oil are likely safe when taken in amounts common found in food and when taken and medicinal amounts or applied to the skin.

The leaf is considered safe when it is used for medicine for up to 8 weeks.

The safety of using peppermint leaf over the long-term is unknown.

The use of peppermint may lead to some side effects such as heartburn and allergic reactions including headache and flushing.

When taken in pill form, peppermint is coated with an enteric coating to prevent contact with the stomach. It’s possibly safe for children 8 years of age and older.

Quebracho extract

Quebracho extract, made from the bark of a hardwood tree, is indigenous to South America.

There are more than 15 different species and many are used for commercial purposes, but only a few are used medicinally.

This supplement uses the red version. It is a source of the world’s most stable polyphenol which makes it of interest to medicine.

Much of the info available is on the white quebracho, but the red variety is proving more beneficial regarding gut-related issues.

The extract naturally contains tannins, a water-soluble polyphenol. These are large flavonoids that readily bond to hydrogen to significantly reduce methane production and disrupt and destroy bacteria lipid bilayers.

The polyphenols here have been considered some of the most prolific for reducing methane in the guts of animals that have a specialized stomach that firms its food before digestion.

Quebracho is a macromolecule so it isn’t absorbed by the intestines and remains in the gastrointestinal tract interacting with substance present without being absorbed into the bloodstream.

Because of its ability, the polyphenols are not denatured by gastric acid or pancreatic enzymes. It is an extremely powerful antioxidant.

Because of this, it interrupts inflammatory processes.

As amazing as all of this sounds, a study published in the Journal of Animal Science showed, “Feeding up to 2% of the dietary DM as quebracho tannin extract failed to reduce enteric methane emissions from growing cattle, although the protein-binding effect of the quebracho tannin extract was evident.”

Horse chestnut

Horse chestnut is a plant. Its seed, flower, leaves, and bark are used to make medicine.

It contains a significant amount of a poison called esculin and it is extremely lethal if eaten raw.

The seed and leaf are used for treating varicose veins hemorrhoids, and swollen veins.

The seed is used to treat diarrhea, fever, and enlarged prostate. They can also be processed so that the active chemicals can be removed in concentrated resulting in an extract that’s used to treat blood circulation problems.

The leaf is used for eczema, soft tissue swelling from bone fracture and sprains, cough, arthritis, joint pain, and menstrual pain.

The branch bark is used for malaria and dysentery. Some people apply the bark to the skin for lupus and skin ulcers.

It’s thought to work because it contains a substance that thins the blood, so it makes it harder for fluid to leak out of the veins and capillaries. It weakly promotes fluid loss through the urine to help prevent water retention.

It is likely safe for most people when they take a standardized seed extract for a short period. Make sure to look for products that have the toxic substance esculin removed.

Horse chestnut products can sometimes cause side effects such as upset stomach, itching, headache and dizziness.

Horse Chestnut

Pollen from the horse chestnut flower can cause allergic reactions.

Suppositories that use horse chestnut may cause inflammation and itching in the anal area.

Raw horse chestnut seed, bark, flower, and leaf are unsafe and extremely lethal when taken by mouth by adults or children.

Not enough information is known about the safety of using horse chestnut seed extract from which the poison has been removed during pregnancy or breastfeeding.

Because horse chestnut may slow blood clotting you should avoid it if you have a bleeding issues.

Horse chestnut may also lower blood sugar so if you have blood sugar problems watch for signs of blood sugar that’s too low and check your blood sugar carefully.

Some reports say horse chestnut seeds and bark can irritate the gastrointestinal tract so you should not use them if you have bowel or stomach problems.

There is one report of liver injury associated with using horse chestnut so if you have a liver condition it is best to avoid using it.

If you are allergic to latex, you might also be allergic to horse chestnut. There is concern that horse chestnut may make kidney problems worse.

Because horse chestnut might slow blood clotting, it may increase the risk of bleeding if used before surgery.

People using horse chestnut should stop for at least two weeks before surgery.

A double-blind study of patients suffering from bloating, constipation and abdominal discomfort published in the World Journal of Gastrointestinal Pharmacology and Therapeutics (WJGPT) revealed that 88% of patients found relief after using Atrantil.

Atrantil and research

While this certainly sounds impressive, the text of the study reveals there were only 24 participants involved.

“Twenty-one of 24 patients (88%) responded to the dietary supplement as measured by individual improvements in VAS scores for abdominal pain, bloating and constipation symptoms comparing scores prior to administration of the extract against those reported after 2 wk. […]

“There were also significant improvements in individual as well as mean VAS scores after 2 wk of administration of the combined extract compared to baseline for abdominal pain [8.0 (6.5, 9.0) vs 2.0 (1.0, 3.0), P < 0.001], bloating [8.0 (7.0, 9.0) vs 1.0 (1.0, 2.0), P < 0.001] and constipation [6.0 (3.0, 8.0) vs 2.0 (1.0, 3.0), P < 0.001], respectively. Also, 21 of 24 patients expressed improved quality of life while taking the formulation. […]

“There were no reported side effects to the administration of the dietary supplement in this practice population suggesting excellent tolerance of the formulation. […]

“This pilot retrospective analysis of symptom scores from patients before and after consuming a quebracho/conker tree/M. balsamea Willd extract may support the formulation’s use in IBS-C.”

The study was also authored by the same KBS Research company that develops the supplement. We would like to see similar results repeated with an independent third-party study.

Does Atrantil Work?

It seems to work for the majority of people who try it and use it consistently. However, if the source of your digestive discomfort, constipation, and bloating is not a result of bacteria in your gut, you likely won’t see the same results.

This does not work the same way probiotics or digestive enzymes do.

However, the science that shows this product is effective has been completed by the company that makes the supplement, so we don’t know with 100% certainty that we can trust it.


Atrantil Benefits and Results

It seems that people suffering from occasional bloating and stomach discomfort symptoms have seen relief within a couple of hours of taking one dose of two capsules.

It’s best to continue taking it up to three times a day until you achieve significant relief.

Typically, you can expect your roots achieve this level of relief within 7 to 10 days.

However, for some sore after hours, it may take anywhere from 20 to 30 days to experience significant relief.

Weight Loss

Details on Atrantil and Weight Loss

Atrantil is not an appetite suppressant or a fat burner so it likely will not produce weight loss results like many of the other supplements being reviewed.

However, if you are someone who struggles with regular bloating and abdominal discomfort with or without constipation, diarrhea, or both, you may notice that you feel a lot better.

You may see some minor weight loss as a side effect of getting your digestive system healthy and keeping it that way.

Can Atrantil Help SIBO?

SIBO or small intestinal bacterial overgrowth as defined by Gastroenterology & Hepatology is the presence of excessive bacteria in the small intestine; it is frequently the cause of chronic diarrhea and malabsorption.

Patients with SIBO often suffer from nutritional deficiencies and struggle with unintentional weight loss.

The botanicals in Atrantil may be able to help kill off some of that access bacteria to make it easier for patients to absorb nutrients and maintain a healthy weight. However, Atrantil is not marketed as a cure for SIBO.

How to Take Atrantil

You can take this up to three times per day as needed. For best results, take two capsules three times a day with food.

You can take it anytime even after your symptoms have started with or without food. Each bottle contains 90 capsules so it will last a month.

Atrantil side effects

Side Effects

Potential Atrantil Side Effects

Though the side effects profile for Atrantil has been minimal, some customers have experienced mild stomach discomfort when taken on an empty stomach.

You can alleviate those symptoms by taking Atrantil with food. If your bacteria load is high, you can experience temporary symptoms such as muscle ache, headache, and a foggy feeling.

This is suggested that a sign that the supplement is working and then reaction is related to toxins from the bacteria causing a mild reaction.

Atrantil Did not be taken by anyone who is pregnant or nursing, or anyone with an allergy to these ingredients. This product should be kept out of reach of children.

Bottom Line

The Bottom Line on Atrantil

We like that the focus with Atrantil is on gut health. We also like that there’s research supporting the effectiveness of the ingredients. There’s little mention of side effects and users state it works. However, there are alternatives to Atrantil that go beyond supporting gut health.

Weight loss involves multiple factors and diet and exercise are just the start. You’ll need a clinically-tested comprehensive weight-loss program that help you reach your goals.

Among the best we’ve seen is one called Noom. This weight-loss system provides you with everything you need to start meeting your personal goals, including human coaching, extensive food tracking, customized meal plans, and more.

6 Atrantil Reviews

  • Incorrect information about this priducty
    Eileen Gregorkiewicz

    Don’t understand your math if you say to take 2 tablets 3 times a day that amounts to 180 tablets a month , but you say a bottle of 90 will last a month. Please explain this to me ! That means you’d have to purchase 2 bottles which you do not state

    • Montana (Editor)

      Hello Eileen. According to the product’s instructions, users can take two capsules up to 3 times a day, meaning you can take between 2-6 capsules a day depending on your needs. If you only consume 2 capsules a day, a bottle containing 90 capsules can last up to a month.

  • Atrantil Worked For Me
    Tom (Verified Purchase)

    All I can say is Atrantil worked great for me. I had severe stomach gas and bloating while exercising. Especially while swimming. I tried probiotics and Gas X but they did not work. So I got Alrantil and took one tablet in the morning and one at night. The bloating and gas are now gone. It worked for me after taking it the first day. I suggest buying the travel pack to test it. Like any product, it will not work for everyone.

  • amy (Verified Purchase)

    After 6 months of dealing with C Diff, Crohn’s Flare, and more C Diff I have been left with chronic diarrhea and bloating and belly pain. After using Atrentil for the first 3 days I noticed decreased bloating, and less diarrhea, by the end of 10 days I was pain free, and having one normal bowel movement a day. I was taking 6 capsules a day, By the 11th day, my symptoms of pain and diarrhea returned. And I am almost back to the chronic pain, bloating and irregular bowel activity. I am not sure if I should continue.

  • Rosie

    My initial four days have been gassy and diarrhea do you need to get used to it at first or is it not for me

  • Works very well for SIBO
    Joanne Cole (Verified Purchase)

    Atrantil was the only product that helped my SIBO…after 8 months of being really ill, taking antibiotics and probiotics, Antrantil got me well again.
