Bacteria used in Hypro-tect are mostly lactic acid bacteria. Intestines are the most important environment for activity of probiotic bacteria. These bacteria enter the intestines, propagate, and create an appropriate environment for digestion and absorption of nutrients. The acid produced by these bacteria in the intestines reduces the pH; and inhibits the growth of pathogens such as E. coli and Salmonella. Moreover, the ability of probiotic bacteria to adhere to the epithelium of the intestines, colonization and pathogenesis of harmful bacteria are restricted.
