Nutrabiotix fiber is a prebiotic and is able to promote gut health through changes in the stool microbiota composition favoring saccharolytic bacteria like Bifidobacteria and diminishing proteolytic bacteria like Clostridia. This change in the intestinal microbiota composition should result in increases in the products of carbohydrate fermentation [SCFA] and decreases in the products of protein breakdown [indoles and phenols] in the stool. Also, the fiber is well tolerated and without side effects and is an effective fiber that increases stool bulk and regulates bowel movement.
