Atrantil Review - 14 Things You Need to Know

Atrantil is relatively new, but it’s been making some headway in the industry. Developed by a gastroenterologist, it claims to relieve bloating, abdominal discomfort, and changes in bowel habit. We’ve reviewed hundreds of products that claim using laxatives can promote weight loss. Is this one of those brands?

With a small ingredient list, our research team wanted to understand better 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.

Atrantil can be purchased through their Official Site.

What is Atrantil?

Atrantil is a natural botanical-based dietary supplement aimed at providing relief from digestive issues such as bloating, abdominal discomfort, and irregular bowel habits. Distinct from probiotics and digestive enzymes, it focuses on balancing digestive health and addressing gas-related issues in the gut. This supplement is designed for daily use, offering a non-probiotic, non-enzyme approach to managing digestive disturbances.

Let’s take a quick look at these ingredients.

  • Phytotherapy Research – “In addition to traditional food flavouring uses, M. × piperita is well recognized for their traditional use to treat fever, cold, digestive, anti‐viral, anti‐fungal and oral mucosa and throat inflammation.”
  • World Journal of Gastrointestinal Pharmacology and Therapeutics – When we started researching quebracho extract we thought there was nothing there, but we stumbled on a small study on Atrantil – this exact supplement. We rarely find studies on supplements, so we were surprised. Based on the study, which involved 24 participants, “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.”
  • Food Chemistry – Horse chestnut offers strong antioxidant activity, but we found no connection to digestive health. In some literature, the extract is used as a diuretic to remove excess fluid from the body.

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 the 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 relieve 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 with both the leaf and oil being 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 various 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 applies to the skin for headache, muscle pain, nerve pain, toothache, inflammation of the mouth, various joint conditions, an 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 is not proven.

Today it is sold as a dietary supplement, so the FDA does not have to prove it’s effective for it to be on the market. 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 commonly found in food and when taken in medicinal doses or applied to the skin.

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

The safety of using peppermint leaves 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 eight 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 substances 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. However, the study was published more than 10 years ago, meaning its results may not be considered relevant anymore.

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 before 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.

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

However, the science that shows this product is effective was 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 to 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.

Atrantil benefits

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.

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 is the presence of excessive bacteria in the small intestine; it is frequently the cause of chronic diarrhea malabsorption.

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

The botanicals in Atrantil may 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 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 that 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.

It suggests a sign that the supplement is working and then the reaction is related to toxins from the bacteria, causing a mild reaction.

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

If you take any other medications, please consult with your doctor or other health-care professional before beginning to use this supplement.

What Users Are Saying

What Users Are Saying

“I absolutely love this product. I have been using it for a long time. Can not be without it.”

“At first Atrantil seemed to help with my bloating and C-Sibo, but after 2 weeks it most definitely gave me high blood pressure and diarrhea. I couldn’t sleep several nights because of the pressure throughout my body, the ear ringing and popping, muscle weakness and body shakes. Thankfully I finally realized it was this product because that could’ve been serious had I continued to use this. One of the ingredients clearly messes with your potassium levels. Do your due diligence beforehand because there are no refunds.”

“Best thing I have used. Follow the directions and you’ll be thankful.”

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.

Also, the makers of Noom are so confident in their system, that they’re offering a free trial offer.

  • Saved my life….not kidding
    Michael Russing (Verified Purchase)

    I will say Atrantil changed my life. I had sibo c and after about 5 days I saw real improvement…that was a year ago. I use about twice a day as a regular supplement. I take 2 with a meal that have 8n the past caused issues and I seem to have no issues. I keep an extra bottle at home and travel with one. I would do a free commercial for the maker if they asked.

  • Severe stomach pain
    Karen (Verified Purchase)

    Made me extremely sick at my stomach felt like my insides were on fire I started out taking two which made me totally sick call the doctor that provided me with the pills they told me to cut it back down to one so I took one the next day Three times as directed to give it a chance I literally felt like I was going to die definitely to not work for me

  • Did the opposite of what it's supposed to!
    J (Verified Purchase)

    I am sensitive to a lot of things, so I decided to take this slowly. I started with 1 tablet in the morning with breakfast for 3 days…. then added a tablet at dinner for a couple of days…. then added the lunch one. It seemed to be working for the gas, which is my major complaint. My bowel movements have always been great, if I do say so myself 🙂 Then came the day I started two at breakfast. No poop. Felt and looked really bloated. It’s been 3 days with no tablets whatsoever. Finally pooped a little this morning…. I look pregnant. Not happy. Now where is that receipt……

  • 7 days in
    Kelly Allhands (Verified Purchase)

    I started taking 7 days ago for bloating and ibs c and now have diarrhea…is this normal?

    • Montana (Editor)

      Hello Kelly. Atrantil claims it helps relieve bloating and gastrointestinal distress. However, some reviews claim it did the opposite. It may be best to discontinue use and consilt with a medical professional to see what your next steps are.

  • happy with results
    Kay (Verified Purchase)

    I have been taking Atrantil (2 caps 3x daily) and a digestive enzyme ( once a day) and have had great results. My bowel movements have straightened out and no diarrhea after one week. Gas is minimal and bloating is all but diappeared. I have been struggling with chronic diarrhea since my gallbladder was removed 45 years ago. I am very happy with the results. I had taken tetracycline for 4 years as a teen for acne and believe my good bacteria was depleted from taking this med so long. Now I am able to go as I please without the worry of accidents.

  • 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
