Windsetlers are small, easy to swallow gel capsules that contain the active ingredient simeticone. This anti-foaming agent works by uniting all the small bubbles of gas that can get trapped among the stomach contents, & then forms large bubbles that are more easily expelled by burping or passing wind. Simeticone acts locally in the gut & is not absorbed into the bloodstream. Windsetlers Gel Capsules are sugar free & suitable for adults, the elderly & children.
