We contribute to the health and well-being of people around the world. We enable groundbreaking biomedical research. We facilitate the uptake of vital pharmaceuticals. We are pioneering exciting new collagen peptide-based health innovations. For over 130 years, our work – which by default contributes to a circular economy – has centered on deepening our knowledge of the collagen molecule. We are the collagen company. 

collagen triple helix

Designed by nature, native collagen is a structural protein found in our bodies’ connective tissue. Composed of thousands of amino acids in a tight triple helix structure, collagen plays an essential role in the body, giving our bodies that astonishing combination of strength and flexibility.  

Humanity has prized collagen for centuries. Our earliest ancestors created collagen-rich bone broths. Today, we extract gelatin and collagen peptides from native collagen for an exciting and growing range of applications and benefits across numerous industries: from biomedicine & pharma to foods, nutraceuticals & supplements, and more.

Our journey with collagen began in 1891 with repurposing animal by-products from the meat industry to create gelatin. 

Since our beginnings as a family-owned business in France, Rousselot has been a part of numerous leading industrial groups, such as Elf Sanofi, SKW, VION Ingredients, and – since 2014 – Darling Ingredients. The company has steadily expanded, by acquiring gelatin factories and establishing sales structures across Europe, the Americas, and Asia. In 2023, the Brazilian group Gelnex, also specializing in gelatin and collagen, became part of Darling Ingredients. 

Today, we combine industry-leading research with sustainable, state-of-the-art production processes to deliver high quality collagen-based solutions. As a world-leading collagen and gelatin company, we offer a range of over 400 products derived from collagen.

Our research shows that the collagen molecule has numerous undiscovered (health) benefits. This is why our scientists are engaged in ongoing studies, continually uncovering new and highly specific advantages.
