8.5 g of fiber – The intestinal lining replaces itself every seven days. Certain plant fibers, acacia gum, wheat grass, and psyllium seed among them, stimulate healthful renewal of the lining of the intestinal tract. They provide food for cells of the intestinal mucosa and support normal cell replacement. Wheatgrass leaf powder, psyllium, and acacia fibers are fermented by the strains of probiotic bacteria in Improved Bowel Support to generate short chain fatty acids (e.g. acetic, butyric and propionic), a primary fuel for the growth of healthy cells in the intestinal lining.
