Stevia Plus - 50 packets Don't Just Sweeten Your Diet - Supplement It! Features: Stevia Plus contains the intensely sweet glycosides (200-400 times sweeter than sugar) extracted from Stevia leaves, and a prebiotic nutritional supplement called Frutafit Inulin Fiber (fructooligo-saccharides, also known as FOS). Frutafit Inulin Fiber (FOS) selectively nourishes the friendly bacteria (lactobacillus and bifido-bacteria) in the intestines, thus increasing the number of these good bacteria that will most benefit the body's gastrointestinal functions. Frutafit Inulin Fiber (FOS) provides a powerful fiber effect but without the required bulk usually found in other fiber products. In fact, just four SteviaPlus packets contain as much fiber as a bowl of whole grain cereal.
