Probiotics are friendly microorganisms that normally colonize the gut and the word Pro-Biotic literally means, For Life. There are normally trillions of microorganisms living within the healthy human intestinal tract, and are considered to be symbiotic, meaning that they live in harmony with humans, and for their mutual benefit. These microorganisms normally consist of both yeast and bacterial species, including Streptococcus, Lactobacillus, and Bifidobacterium bacteria.* Having a balanced and varied microbiota environment is known to be critical for human health, as it helps to maintain the health and function of the intestinal lining, and thus promotes normal intestinal motility. Probiotic organisms also support proper digestion, play an important role in the bodys detoxification process, and are known to be critical for healthy immune system function.* Each NOW® Probiotic-10 packet has at least 10 billion live organisms consisting of Probiotic bacterial strains that are known to colonize the human GI tract plus Inulin to promote the growth of a balanced spectrum of organisms throughout the intestinal tract.* This convenient unflavored powder mixes easily in water or juice, is appropriate for vegetarians and vegans, and is dairy, wheat and gluten free.
