IBgard Difference

IBgard® Overview

IBgard is a medical food specially formulated for the dietary management of IBS. IBgard capsules contain individually triple-coated, sustained-release microspheres of Ultramen®, an ultrapurified peppermint oil along with fiber and amino acids. In a 2016 peer reviewed and published clinical study§, IBgard has been shown to start working in as early as 24 hours*. IBgard can help to...

  • Normalize 1 the digestion and absorption of food nutrients that have been compromised by IBS.
  • Manage the accompanying and often distressing group of symptoms of IBS. These include, at varying times, abdominal pain, discomfort or cramping, bloating or gas, diarrhea, constipation, or bouts of diarrhea interrupted by constipation, urgency of bowel movement, sense of an incomplete bowel movement, and pain at bowel movement. 
  • Promote 2 bacterial balance in the small intestine (part of the lower gut).

IBgard Caplet with Microspheres

In addition to peppermint oil, each IBgard serving of 2 capsules provides approximately 640 mg of fiber and approximately 400 mg of amino acids from gelatin protein. These, too, are intended to help toward normalizing the lining of the gut (gut mucosal barrier).

The IBgard Difference - Advanced Science

Peppermint oil and its principal component, l-Menthol, has a history of effectiveness in IBS. However, until recently, its targeted delivery to the small intestine had posed a challenge. IBgard utilizes breakthrough science via SST® (Site Specific Targeting). This technology delivers microspheres of peppermint oil (in a solid state), along with fiber and amino acids, quickly and reliably where they are needed the most in IBS – predominantly in the small intestine. Besides helping manage IBS symptoms, this is also important as 90 to 95% of nutrient absorption occurs in the small intestine.3 IBgard helps normalize the lining of the gut (gut mucosal barrier) and thus helps normalize the digestion and absorption of food nutrients.

Why Targeting the Small Intestine is So Important

The symptoms of IBS often occur within 90 minutes of meals. This reflects the time it takes for food to reach the small intestine. Recent scientific and clinical evidence points to the small intestine as the site of the disruption in the lining of the gut (gut mucosal) barrier and where transit time can also be disrupted. Thus, food can move too fast or too slow, causing diarrhea, constipation or bouts of diarrhea interrupted by constipation. This is also the site where abdominal pain originates, probably from irritated nerve endings in the gut or from trapped gas. Only IBgard utilizes SST® (Site Specific Targeting) technology to deliver its ingredients to the small intestine. IBgard has been specially formulated so that it can be taken 30 minutes before or after meals to provide its calming properties. Note: Taking IBgard 30 minutes before a meal is preferable as it enables the protective effect of IBgard to get to work as early as possible.
