IntelliFlora has been proven to promote intestinal health and is designed to create a balance of microbes within your dog or cat"s gastrointestinal tract. IntelliFlora is most often used during periods of diarrhea, stress and antibiotic use. IntelliFlora contains a blend of four different bacterial strains including Enterococcus faecium, Lactobacillus acidophilus, Lactobacillus plantarum and Lactobacillus rhamnosus (the leading brand only offers Enterococcus faecium). These four strains are instrumental in fortifying intestinal cells while inundating the bad, unhealthy bacteria present within your dog or cat"s GI tract. There are also a number of negative side effects caused by antibiotic therapy as well (including diarrhea, digestive upset and an overall depletion of healthy bacteria in the animals digestive system). It is recommended that IntelliFlora be used during antibiotic therapy, but given during alternating times with regard to the administering of the antibiotic itself. IntelliFlora also contains a variety of essential vitamins and nutrients including Vitamins C, A, E, Zinc and Manganese. All of which are needed for your dog or cat"s proper metabolism, vision and immune system functioning.
