Michigan: Immunity private label

Michigan has Lansing as its capital and Detroit as its largest commercial city, serving a population of 10 million. Key cities include Detroit, Grand Rapids, Ann Arbor, Lansing. The state's distinctive supplement footprint is anchored around the Detroit metro DTC cluster and Grand Rapids natural-products retail corridor. On the supplement industry signal: Amway HQ (Ada/Grand Rapids) — anchor of US direct-sales supplement industry. Michigan is a strong Midwest natural-products retail market. For brand owners briefing DAT Supply, Michigan 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 Port of Detroit (Great Lakes intermodal access), 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.
