Microorganisms are invisible agents of change, facilitating our mobility, protecting us from disease, and helping us adapt to our ever-changing environment. At Gnosis by Lesaffre, microorganisms are a part of our workforce.

We harness their power and biotransformation processes like fermentation to cultivate nutritional actives, probiotics, and nutritional and functional yeasts that benefit human health and wellbeing. We strive to create a world that moves better, digests better, ages better, feels better, and, ultimately, lives better thanks to microorganisms and biotransformation.

We draw on our focused research and development capabilities, rigorous quality and regulatory standards, and extensive clinical validation procedures so that we can develop effective solutions for the Nutritional Health & Wellbeing, Digestion & Gut Health, Mobility & Joint Health, Reproduction & Women’s Health, and Mood & Cognitive Health markets. Our processes are replicable, reliable, and meticulously studied, so that we can maintain unrivaled quality and consistency while scaling up production.
