What Rousselot does
Rousselot is the health-brand and operating subsidiary of Darling Ingredients Inc. (NYSE:DAR), positioned as a global leader in gelatin and collagen peptide ingredients with approximately 30% combined global market share. The company operates 16 production facilities across four continents and offers more than 400 products organized into three core lines: Peptan collagen peptides for health and nutrition applications, functional gelatins for food, pharmaceutical, and nutraceutical uses, and biomaterials (including X-Pure) for biomedical and regenerative medicine research. Sub-brands such as Colartix (joint health) and Nextida GC (metabolic and blood glucose support) extend the portfolio into clinically targeted health claims, protected by multi-jurisdictional patents.
The underlying technology relies on collagen and gelatin ingredient solutions derived from animal agriculture and food industry byproducts under a circular-economy model that is vertically integrated through parent Darling Ingredients. Rousselot's go-to-market is enterprise B2B, with direct sales partnerships to nutraceutical, functional food, pharmaceutical, and biomedical manufacturers, supported by quote-based pricing for custom formulations and volumes. Trade-show presence at Vitafoods, Natural Products Expo West, and COMPAMED, combined with research-driven content marketing, anchors mid-funnel buyer engagement.
Rousselot generates revenue through one-time sales of collagen peptides, gelatins, and biomaterials across four customer segments — Health and Nutrition, Functional Food and Beverage, Pharmaceutical, and Biomedical — with primary emphasis on the first three. Pricing is not publicly disclosed. The company is currently positioning to capture emerging demand from GLP-1 medication users, regenerative medicine developers, and consumers seeking science-backed targeted-health ingredients, while reinforcing sustainability credentials through the Upcycled Certified designation for its Peptan range.
