Probi® has spent more than thirty years investigating the safety and efficacy of our probiotic strains. We conduct state-of-the-art preclinical and clinical studies, to evaluate the health effects and underlying mechanisms of our probiotics. Our scientists, and research groups around the globe, have published more than 60 human clinical trials on the LP299V® strain alone, primarily in the fields of digestive health and iron absorption.
Other strains have proven effective in other areas, such as immune health and bone health.
Beneath we present a few of our studies in selected areas.
