Supplemental bacteria are called probiotics, meaning “for life” or “in support of life”, because they are the natural guardians of robust intestinal health and vitality. Friendly or probiotic bacteria toil 24 hours a day, holding at bay and dominating the many pathogenic bacteria, viruses, yeast, and other microorganisms that unavoidably inhabit the intestinal tract. Given opportunity, the pathogens succeed in colonizing by adhering to the intestinal tract, inflicting disruptions to our intestinal health and throughout the whole body. Beneficial bacteria also have a profound effect on the immune system, boosting immunity to combat allergies, flu, and the common cold.
The human intestinal tract contains trillions of bacteria in a natural but delicate state of balance between the beneficial bacteria and their good effects, and the pathogenic microorganisms and their potentially adverse effects. Under conditions of high stress or prolonged stress, antibiotic therapy, vacation or business travel, and encounters with food or water-borne pathogens, this natural protective balance can be disrupted, resulting in a decline in the number of beneficial or probiotic bacteria.
Natural Factors Acidophilus & Bifidus contains three strains of probiotics to assist with the maintenance of normal intestinal health: Lactobacillus rhamnosus, Lactobacillus acidophilus, and Bifidobacterium bifidum. The capsules contain goat milk powder to provide an excellent environment to grow lactic bacteria.
