Illinois: Collagen private label

Illinois has Springfield as its capital and Chicago as its largest commercial city, serving a population of 12 million. Key cities include Chicago, Naperville, Aurora, Rockford, Springfield. The state's distinctive supplement footprint is anchored around the Chicago metro CPG/foodservice corridor and Illinois's ingredient-and-flavour-house cluster. On the supplement industry signal: Walgreens HQ (Deerfield) + Jewel-Osco regional HQ + Chicago O'Hare top-3 US air-freight + BNSF Logistics Park intermodal rail. Chicago is a top-five US grocery-private-label sourcing market. For brand owners briefing DAT Supply, Illinois is treated as a US-market launch operating under federal DSHEA rules: the brand owner is the responsible label holder, the product is manufactured under 21 CFR Part 111 quality-managed manufacturing rules, and any state-specific labelling (the most common being California Prop 65) is reviewed at the artwork gate. Logistics typically run through the Chicago intermodal complex (the largest US inland rail hub), which DAT coordinates as part of a single project alongside manufacturing, documentation and ingredient sourcing. Where the brand owner has multi-state ambitions, neighbouring markets are listed in the internal links below for a single artwork project covering the wider region.
