IBgard Review: Digestive Relief or Waste of Money?

IBgard Review: Digestive Relief or Waste of Money?

| |
| |

IBgard is a gut health supplement that’s used to treat a number of gastrointestinal symptoms. The brand claims that their supplement helps manage cramping, diarrhea, bloating, constipation, gas and more.

But does IBGard contain ingredients shown in clinical studies to improve gut health? Does it contain any questionable additives? How do real users rate and describe the effects of IBgard? And why was the brand's manufacturer sued?

In this article we’ll answer all of these questions and more, as we analyze the ingredients in IBgard to give our take on whether or not the supplement is likely to be effective, and whether or not it's healthy.

We'll also discuss the risk of side effects, feature real customer reviews, and explain why the manufacturer of IBGard was sued.

Ingredient Analysis

IBgard ingredients

Peppermint oil is the only active ingredient in IBgard, at a dosage of 180 milligrams (mg) per serving.

This ingredient is a well-studied botanical treatment for stomach and digestive ailments.

A 2018 medical review found that peppermint oil can help heal the gut and relieve digestive symptoms.

Specifically, peppermint oil can relax smooth muscles, has anti-inflammatory activity and is antimicrobial. The study authors concluded that clinical trials “support its use” in treatment of digestive issues.

Peppermint oil is so effective for digestive disorders that it’s even being studied for the treatment of irritable bowel syndrome (IBS).

A clinical trial published in the Gastroenterology journal found that peppermint oil which was formulated to release in the intestines rather than in the stomach (like IBgard) caused significant reductions in abdominal pain and overall discomfort in IBS patients.

IBGard also contains three inactive ingredients we consider to be unhealthy.

Titanium dioxide is a colorant which is banned in the EU for use as a food additive due to toxicity concerns.

Yellow 5 and Green 3 are artificial food dyes.

As we documented in our Metamucil review, clinical studies have documented toxicity concerns with all food dyes currently approved for use in the US.

Overall, we consider IBgard likely to be effective for digestive symptom relief, but we don't currently recommend the supplement due to the inclusion of the inactive ingredients discussed above.

Does IBgard Cause Side Effects?

Unlike the majority of dietary supplements we review on Illuminate Health, IBgard has been studied in a clinical trial published in a peer-reviewed journal, which makes it easier to assess the risk of side effects than based on ingredients alone.

A clinical trial published in the Digestive Diseases and Sciences journal tested the effects of IBgard in patients with IBS, and reported on side effects.

No serious adverse effects were noted, and the group taking placebo pills actually experienced more side effects than the group taking IBgard capsules.

This suggests that IBgard is unlikely to cause any side effects.

We consider this to be a major benefit of IBgard compared to other over-the-counter (OTC) digestive treatments.

Why Was IBgard’s Manufacturer Sued?

In 2021, Nestlé Health Sciences (the manufacturer of IBgard) was sued in a class-action lawsuit alleging false advertising, according to ClassAction.org.

The subject of the lawsuit was the brand’s claims that their supplement is “clinically proven” to relieve symptoms of IBS.

The plaintiffs claim that there were methodological issues with the clinical studies funded by Nestlé, and that it’s misleading for the brand to make this health claim.

The lawsuit also disputes the description (at the time) of IBgard as a “medical food,” because the FDA had not (at the time of the lawsuit) published any specific nutritional requirements for patients with IBS which are different from nutritional requirements for healthy patients.

At the time of updating this article, it’s unclear if this lawsuit is ongoing or if it’s been settled.

We do not consider this lawsuit to pose any legitimate concerns that should worry consumers.

It’s mostly regarding semantic distinctions and we would actually agree with Nestlés claims in this case, because this supplement has been found to have favorable effects in at least one legitimate clinical trials published in a peer-reviewed medical journal.

Where to Get the Best Price

IBgard is sold at a variety of online retailers.

Here’s a price breakdown for a one-time purchase at the time of updating this article:

CVS: $37.49 (free shipping, link)

Walgreens: $34.99 (free shipping, link)

Target: $30.99 (plus shipping, link)

Amazon: $27.44 (free shipping, link to official Amazon listing)

Walmart: $25.42 (free shipping, third-party seller, link)

IBGard is currently almost 40% cheaper at Amazon and Walmart than at CVS.

While Walmart has a slightly better price, the Walmart listing is from a third-party seller, so it may be safer to purchase directly from the brand at Amazon.

Stay up-to-date on our research reviews


IBgard is a well-formulated dietary supplement and we believe that it’s likely to relieve digestive symptoms.

The manufacturer of this product has funded at least one clinical trial showing it to be effective, and also showing that the supplement does not cause side effects.

We do not currently recommend IBgard due to the inclusion of a coloring ingredient that’s banned in the EU, and due to the inclusion of two artificial colors.

Online reviews of IBgard are relatively favorable, and either Walmart or Amazon currently has the best price on the supplement.

IBgard was sued in 2021 over claims of false advertising, though we don’t find the lawsuit to bring to light any information that should be of concern to consumers.
