Institut Rosell

Institut Rosell, now operating as Lallemand Health Solutions, is a pioneer in the research and production of probiotics for human health. Founded in 1934 in Montreal, the company was one of the first to develop industrial-scale fermentation for beneficial bacteria. Following its acquisition by Lallemand in 1998, it has expanded into a global leader, providing vertically integrated services from strain selection to finished product manufacturing. The company's portfolio features well-documented probiotic strains, including the Rosell® and Harmonium® lines, which are supported by extensive clinical documentation. Their products target diverse therapeutic areas such as gastrointestinal health, natural defenses, and the gut-brain axis. Institut Rosell remains a key innovation hub for microbiome-based solutions, serving the dietary supplement and functional food industries worldwide.
