Bulletproof 360 INC recalled Bulletproof Unflavored Collagen Protein High Performance Building Blocks Dietary Supplement, packaged in a 16-oz. composite-film bag, UPC: 8 in a Class I action — the FDA's most serious tier, reserved for products with a reasonable probability of causing serious health consequences or death on Jan 23, 2018.

The FDA listed the reason as an undeclared allergen: "Bulletproof Collagen Protein is recalled due to undeclared milk. The actual product inside the package is whey (milk) protein but mis-labeled as collagen protein." Allergen mislabeling is the leading cause of U.S. food recalls, because a missing declaration can trigger a reaction in someone who reads the label and believes the product is safe.

The product reached multiple states, recorded by the FDA as "distributed in CA, CO, CT, FL, GA, IA, IN, NH, NY, PA, SC, TX, WA, and WI." A multi-state footprint means the same lot can surface in households far from the producer. The recalling firm is based in Seattle, WA. The recall covers firm reported unknown of product. The FDA has Terminated this recall (first reported Feb 14, 2018), its final lifecycle state, indicating the agency considers the corrective action resolved. The historical record remains useful for tracking a brand's recall pattern over time.
