In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue No. 1. Some studies have suggested a possible link between synthetic food colors, including Blue No. 1, and hyperactivity in some children, though the evidence is mixed and not all studies have found a consistent link.
