What SternLife does
SternLife GmbH & Co. KG is a German B2B contract manufacturer of customized functional nutrition products, headquartered in Norderstedt (Segeberger Chaussee 132) and operating as a privately held subsidiary of the Stern-Wywiol Gruppe. Founded in 1998 in Ahrensburg to market granulated lecithin and pivoting into protein bars in 2006, the company today develops and project-manages the full lifecycle of customized protein and energy bars, powdered dietary supplements, Food for Special Medical Purposes (FSMP), and lifestyle nutrition products on behalf of brand owners, retailers, private-label customers, pharmaceutical firms, gym chains, and online sports-nutrition brands. The bar portfolio spans Pure, Basic, Premium, Deluxe, and Grand Deluxe variants in both conventional and vegan formulations, with protein content reaching up to 65%; the powder portfolio covers meal replacement shakes, clear vegan protein, electrolyte and EAA drinks, immune support and gut-health prebiotic supplements, and women's-health life-stage formulations.
Manufacturing is executed through sister companies within the Stern-Wywiol Gruppe ecosystem: HERZA Schokolade operates the certified protein bar facility co-located at the Norderstedt site, while SternMaid runs the Wittenburg powder plant using blending, filling, and fluid-bed technology. SternLife itself focuses on product development, formulation customization, regulatory compliance, and customer project management, drawing on the interdisciplinary expertise of further sister companies (Planteneers for plant-based systems, Hydrosol for stabilization, SternVitamin for micronutrient premixes, SternEnzym for enzyme solutions, and OlbrichtArom for flavors). All products are made-to-order with no catalogue or price list; pricing is quote-based per contract, subject to substantial minimum annual quantities (e.g., 150,000 bars per customer).
The go-to-market motion is sales-led and event-driven, combining direct engagement with executive management, procurement, product management, and R&D buyers at customer firms, active presence at PLMA and Vitafoods trade shows, content marketing through the company's Insights blog, and direct inquiry forms on the corporate website. The company holds IFS Broker, IFS Food, FSSC 22000, and organic (DE-ÖKO-001) certifications across its production footprint, qualifying it for both pharmaceutical-grade FSMP work and major retail private-label programs.
