Intestinal ToneIn our overly-refined, fruit-and-vegetable-challenged diets, few of us come close to the recommended daily amount of fiber. Intestinal Tone contains five grams of fiber per serving, made from the highest grade of all-natural psyllium; considered one of the best sources of both soluble and insoluble fiber on earth. Intestinal Tone contains no chemical stimulants, no sugar or salt, no preservatives - absolutely nothing artificial.
