Private Label Supplement Manufacturing for California Brands

Dietary supplements in California are regulated federally by the US Food and Drug Administration under the Dietary Supplement Health and Education Act (DSHEA, 1994), codified at 21 USC §321(ff) and 21 USC §343. Manufacturing is governed by 21 CFR Part 111 (Current Good Manufacturing Practice for dietary supplements) and labelling by 21 CFR §101.9 (Nutrition labelling) and 21 CFR §101.36 (Supplement Facts panel). Structure-function claims — those that describe an effect on the structure or function of the body without making a disease claim — are permitted under DSHEA §6 when accompanied by the FDA-prescribed disclaimer set out at 21 CFR §101.93(c). The Federal Trade Commission separately reviews advertising substantiation under the FTC Act §5. Common rejection patterns on US labels: (i) language that crosses from structure-function into the drug-claim line, (ii) structure-function copy that omits the FDA-prescribed disclaimer, (iii) percent-daily-value calculations that diverge from the FDA reference values, and (iv) implied weight-loss copy without substantiation. State-specific framework for California: California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) requires a clear and reasonable warning for any listed chemical above the No Significant Risk Level, and is enforced by both the Attorney General and private bounty hunters under Health & Safety Code §25249.7 DAT's artwork gate reviews every claim on the pack against the federal framework and any state-specific overlay (the most common being California Prop 65 for products distributed into California) before the brand owner signs off. Where the brand owner is preparing for a regulated retail channel (Whole Foods, Costco, Walmart, Target, Sprouts, Sam's Club), DAT supports the retailer-specific documentation pack including the Certificate of Analysis, allergen statement, manufacturing-facility registration confirmation, and country-of-origin declarations. Cert panel commonly seen on US pack: USDA Organic, Non-GMO Project Verified, Certified Vegan / Vegan Action, kosher (OU, Star-K, OK), halal (IFANCA or HFSAA), and B Corp where the brand owner has the certification. FDA registration considerations: the manufacturing facility must be a registered food facility under the Bioterrorism Act (FDA Food Facility Registration, renewed biennially) and the brand owner must file a Notification of New Dietary Ingredient (NDI) at least 75 days before introducing any ingredient not marketed in the US food supply before October 15, 1994 — the NDI route is the federal mechanism for new ingredients. Substantiation expectations: structure-function claims must be supported by competent and reliable scientific evidence in the brand owner's file at the time of marketing, per FTC guidance. The substantiation file is the brand owner's responsibility; DAT supplies the formulation specification and ingredient-level documentation that feeds into it. Recall infrastructure: every batch is identifiable by lot code and traceable through the production records, so any FDA Adverse Event Reporting (under the Dietary Supplement and Nonprescription Drug Consumer Protection Act, AERS) or voluntary recall can be executed on a defined production window.
