Acute Immune Modulation by Probiotic Strain

Clinical proof-of-concept study, comparing the acute immune impacts of 3 doses of a probiotic strain to a placebo. This study involves twenty-four participants, composed of healthy adults, who will be taking a placebo and 3 different doses of the probiotic at different times. Testing for immune status and cytokine levels will be conducted to determine the acute impact of the probiotic on immune function when compared to a placebo.
