What it is
Blue 1 is a synthetic food coloring that gives foods a bright blue shade. It is made from petroleum.
Why it's used
Manufacturers add Blue 1 to make foods more visually appealing. It is commonly found in candies, beverages, baked goods, and some dairy products.
Health notes
Blue 1 is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1. JECFA has evaluated Blue 1 and set an acceptable daily intake. EFSA has also evaluated it. Some studies suggest a possible link between synthetic food dyes, including Blue 1, and hyperactivity in some children, though evidence is mixed and more research is needed.
