How this tracker works

Every week we query the California Attorney General’s public 60-Day Notice Search for notices whose product description mentions “protein”, record each notice once (the AG lists a notice once per chemical), and keep only notices that name a protein supplement: a powder, drink mix or ready-to-drink shake. Notices that only name protein bars, snacks, pasta, baked goods or other foods are left out. Brand is taken from the product name where it matches a known brand, otherwise from the first company named that isn’t a retailer, so a manufacturer may appear instead of a brand. Status reflects whether the AG lists a complaint, settlement or withdrawal. We don’t edit or interpret the product names.
