Description : Source Naturals FOS is a complex of fructooligosaccharides (FOS) - a group of naturally occurring carbohydrates which can help promote the growth of beneficial flora in the gastrointestinal tract. The body normally maintains a balance of "friendly" flora in the intestines; unfortunately factors such as improper diet, stress, gastrointestinal problems, and use of antibiotics may disrupt this delicate balance. FOS are long chain sugars which are indigestible by humans, but serve as the "food" for friendly flora, helping increase their numbers in the body. Scientific research conducted in Japan has shown that FOS are selectively used by friendly flora such as bifidobacteria and lactobacilli, while they are not usable by harmful bacteria.* Each Tablet contains 1000 mg of fructooligosaccharides (FOS) Suggested Use : 3 to 4 tablets daily, or as recommended by your health care professional.
