Bifidophilus Flora Force, Improved [Digestive, Intestinal]. The healthy human intestinal tract contains billions of bacteria that live in a delicate balance with each other and in symbiosis with us. We provide them with a home and in turn they break down our food into easily absorbed nutrients and act as natural antibiotics by either crowding out or producing substances to kill unfriendly microorganisms. They also aid digestion in a variety of ways and promote immunity. Factors such as stress, disease, environmental conditions or the use of certain medicines can harm these friendly bacteria. Synthetic antibiotics practically wipe out these beneficial organisms. Improved Bifidophilus Flora Force provides billions of beneficial intestinal microorganisms that offer a whole range of health benefits. This product contains Lactobacillus acidophilus and Bifidobacterium longum plus two additional bacterial strains, Lactobacillus caseii and Lactobacillus rhamnosus for a more complete probiotic formula and added support for the immune system. NSP added fructo-oligsaccharides (short- and long-chain), which support the growth of these beneficial organisms, to ensure the potency of this product. Each capsule provides a good balance of 4 billion beneficial bacteria. This product is recommended for daily use to help maintain a healthy balance of friendly bacteria in the intestinal tract and to support the immune system. Refrigerate or freeze to maintain freshness. Take 1-2 capsules with meals daily.
