The present invention involves a new functional dietary fiber supplement for intestinal health. Unlike conventional products made of plain psyllium husks, the xylitol coating makes oral consumption very convenient. The ground psyllium husk used in this invention is exceptionally effective at facilitating intestinal functions and increasing feces volume. The refreshing flavor of xylitol shields the original smell of psyllium and enhances the product so that it corresponds well with modern taste. When consumed properly, this invention can contribute much to the maintenance of a healthy digestive tract.
