Killer Yeast is a lactose-free, stomach acid–resistant, stable, European patent-pending formula containing DNA-verified Saccharomyces boulardii. This probiotic yeast supports other probiotic organisms in addition to intestinal barrier function and integrity. Research also suggests that Saccharomyces boulardii supports normal immune responses. This product contains 10 billion organisms of S. Boularrdi, a form of non-colonizing yeast that works to prevent dysbiosis during antibiotic use and has been shown to inhibit growth of some species of Clostridia.
