IBgard is a medical food for the dietary management of Irritable Bowel Syndrome (IBS). IBgard utilizes breakthrough science via SST (Site Specific Targeting) to deliver individually triple-coated sustained release microspheres of Ultramen, an ultra-purified brand of peppermint oil, quickly and reliably to the lower gut. In a randomized, multicenter, double-blind, placebo controlled trial, IBgard was shown to start working in as early as 24 hours and this benefit grew when measured at 4 weeks.
