Biotransformation, microorganisms, and your products:
Using what's alive so that we can thrive

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 collaborate with nutraceutical and pharmaceutical brands to develop game-changing products that help their customers thrive. We are true partners to our customers, supporting them with a portfolio of branded solutions, scientific guidance, clinical studies, and more.

We relentlessly explore the potential of microbial biotransformation–an untapped, transformative resource–to develop natural, sustainable, and efficacious solutions.

At Gnosis, we use what’s alive so that we and our planet can thrive.

So, biotransformation. What's that?

We draw on our focused research and applications capabilities, rigorous quality and regulatory compliance, and extensive clinical validation procedures so that we can develop effective solutions for our key markets using biotransformation. Our biotransformation processes, like fermentation and biocatalysis, are replicable, reliable, and meticulously studied, so that we can maintain unrivaled quality and consistency while scaling up production.

1853 - Lesaffre Corporation is born
A collaboration between two lifelong friends, Louis Lesaffre and Louis Bonduelle, who launched the company’s first grain alcohol and Dutch gin plant in northern France. From that site grew Société Industrielle Lesaffre, which gradually proved to be the driving force behind our industrial and commercial boom in yeast.
1882 - Red Star® Yeast First Sold
Three men – Leopold Wirth, Gustav Niemeier and Henry Koch, Jr. – formed a new company, Meadow Springs Distillery, the first manufacturer of Red Star yeast. The Lesaffre Group acquired Red Star in 2001, bolstering the company's yeast leadership. Today, Red Star nutritional yeast is a core offering within our Wellness & Immune Health market segment.
1989 – Gnosis Advanced Biotech established
Gnosis Advanced Biotech – one of the two companies to eventually merge to form Gnosis by Lesaffre – is founded by a group of technicians and scientists to provide a reliable source of scientific and technological services. Based in Italy, Gnosis is a leading manufacturer of active and functional ingredients for the nutrition, cosmetic, personal care, industrial biotech and pharmaceutical industries.
2007 – Lesaffre enters the human health market
The Lesaffre Group establishes Lesaffre Human Care (LHC), a world expert in fermentation, dedicated to the human nutrition, health, and personal care businesses. Over the following 10 years, the Lesaffre Group purchases Omniabios and invests in Gnosis Advanced Biotech, Envera, and Intralytics
2018 – Lesaffre completes the acquisition of Gnosis, creating Gnosis by Lesaffre
The past two years have been full of exciting changes for Gnosis by Lesaffre. For starters, in November 2018, we officially completed our acquisition of Gnosis, merging our human health capabilities. With that came our new name and our new logo. We’re excited to finally share our fully integrated brand with you.
