                                According to WK Kellogg Co, a standard U.S. serving (2/3 cup) of All-Bran Original cereal contains 12 grams of dietary fiber, which represents 44% of the daily recommended value. This high fiber content is derived mainly from wheat bran, a potent source for improving digestive regularity.
