Atrantil Review

Digestion is a tricky subject. Digestion seems like a simple process but is actually quite complex and requires a bunch of things to work together efficiently. Even if one level of enzymes or bacteria is off, you can experience digestive problems.

Digestive supplements aim to fix these problems by reorienting the composition of the gut and intestines. There are many digestive supplements out there, such as Hum Flatter Me, Hyperbiotics PRO-25 Probiotic, and then there’s the one we’ll look at now – Atrantil.

Atrantil (pronounced ‘Ah-tran-teal’) is a digestive supplement that claims it can relieve bloating and discomfort through its blend of natural botanicals.

There are a lot of bogus supplements out there that are no better than snake oil. So we are going to cover Atrantil and figure out if it really is legit or not. We’ll cover the pros, cons, side effects, and costs, then give our verdict if it’s worth it or not in this Atrantil review.

What Is Atrantil?

Antratil is a digestive supplement meant to relieve discomfort from bloating and gas. Atrantil works by attacking the bad bacteria in your gut that produces gas and bloating. Unlike many other digestive supplements, Atrantil is not made with any probiotics or enzymes. Instead, it’s made from botanical extracts like peppermint leaves. The simple ingredients contain no synthetic chemicals and no drugs/antibiotic compounds. Atrantil is also 100% vegan and free from soy or gluten products.

Atrantil comes in capsule form. The directions state that you should take 2 capsules a day up to 3 times a day with your food. You can also take target doses to deal with immediate gastrointestinal discomfort. Atrantil also claims it can help prevent diarrhea and constipation. It also claims that it has no side effects.

Who Makes Atrantil?

Atrantil is created by Dr. Ken Brown, a gastroenterologist operating out of the Dallas area. Dr. Brown created Atrantil in 2008 after wanting to create a drug-free treatment for IBS and other digestive conditions that were free of side effects. Atrantil launched in 2012 under the company KBS Research.

KBS Research claims to be committed to improving the health and well-being of people with various medical conditions. Their products are based around nutraceuticals; products meant to improve health by providing a balanced source of nutrients.

We could not find a BBB page for KBS Research, but the page has a lot of customer reviews. Most reviews tend to be very positive and praise the company’s customer service performance. Moreover, the company seems to have responded to any negative reviews looking to fix the issues. It is good to see a company with a desire to reach out to their customers and fix issues.

How Does Atrantil Work?

Atrantil is a bit different than a lot of other digestive supplements. Atrantil does not contain probiotics or enzymes. Instead, it contains botanical ingredients with high concentrations of polyphenols. Polyphenols are an interesting compound found in plants that has some health benefits, including digestive benefits.

Atrantil claims it works by preventing methane-producing bacteria from feeding on your food. This prevents the bacteria from producing the gas that causes bloating and constipation. The site does not mention a specific mechanism that it uses, though, so we are not sure exactly how it works.

Atrantil does have some evidence behind it, though. According to a double-blind study, Atranil caused a reduction of digestive symptoms in 88% of patients.

Atrantil Ingredients

Atrantil has a simple list of 3 natural ingredients: peppermint leaf, quebracho extract, and horse chestnut.

Peppermint is extremely common in home remedies and treatments. Peppermint has been used for colds, flu, toothache, sore throats, sinus infections, and more. It is normally either chewed on like a leaf or turned into an oil tincture that can be directly consumed.

Peppermint is also a very common substance to use for digestive problems and nausea. It is also commonly used for IBS, cramps, and diarrhea. There is a decent amount of evidence showing the peppermint can relax the smooth muscle in the GI tract, which is why it has its therapeutic effects.

Quebracho Extract is an extract made from the bark of hardwood trees, a tree native to South America. There are actually many kinds of hardwood trees, but only a handful have actually therapeutic properties. The quebracho extract contains a large portion of Atrantil’s serving of polyphenols. These polyphenols can bind to bacteria membranes, which prevents them from producing methane. Quebracho extract contains macromolecules that are not themselves absorbed into the bloodstream but are passed out of the digestive systems like normal. Polyphenols are also known to reduce inflammation so they can reduce upset stomach.

Lastly is the horse chestnut. Horse chestnut flowers, seeds, leave, and bark are used in medicine. Here is the problem though: raw horse chestnut contains esculin, an extremely lethal poison. In small doses, esculin can be a powerful medicinal agent. However, you should avoid horse chestnuts if you have blood issues or blood sugar problems. You should also not take any horse chestnut if you are expecting to have surgery in the near future.
