Webber Naturals Acidophilus Bifidus with FOS is a multi-strain probiotic supplement formulated for complete intestinal health. It contains a combination of friendly lactic acid bacteria that colonize the intestinal tract and contribute to a natural healthy gut flora, in addition to FOS (fructooligosaccharides) that feed the live probiotics and sustain their benefits. This high-potency formula is guaranteed to contain 6 billion active cells per capsule at the time of expiry.The intestinal tract contains billions of microorganisms in a delicate balance of beneficial probiotic bacteria and adverse pathogens. Many factors can affect this balance, including a temporarily compromised immune system, poor diet, stress, and a change in water and food sources while travelling.Lactobacillus and Bifidobacterium strains effectively maintain and establish a healthy microflora balance, while discouraging the growth of opportunistic pathogens, such as yeast, E.coli, Clostridium, and Shigella. Together they help maintain a proper pH balance in the small intestine, protect mucous membranes throughout the digestive tract, and promote regular bowel movements.Acidophilus Bifidus with FOS is available as 60 or 180 vegetarian capsules. It is ideal for individuals who have recently taken antibiotics, those suffering from traveller’s diarrhea, and anyone with declining gut microflora.
