Each serving of Dr. Sue’s Fiber Plus supplement contains a concentrated 5 grams soluble fiber, which is found in oat bran, barley, beans, psyllium husk, and some fruits and veggies. Soluble fiber slows down the movement of food in the digestive system, which in turn regulates bowel movements, increases beneficial gut bacteria, limits cholesterol and triglyceride absorption into the blood, and maintains healthy blood sugar ranges. This unique formulation is free of taste and grit and dissolves in any soft food or drink.
