Source Naturals FOS is a complex of fructooligosaccharides (FOS) - a group of naturally occurring carbohydrates that 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.  Sientific research conducted in Japan has shown that FOS are selectively used by friendly flora such as bifidobacteriia and lactobacilli, while they are not useable to harmful bacteria
