What it is

Blue 1, also known as Brilliant Blue FCF, is a synthetic food coloring. It is produced chemically from petroleum sources.

Why it's used

Manufacturers add Blue 1 to give foods a bright blue color. It is commonly found in candies, chewing gum, mints, cakes, cupcakes, and snack cakes.

Health notes

Blue 1 is an FDA-approved color additive for use in food, drugs, and cosmetics. JECFA has evaluated Blue 1 and set an acceptable daily intake. EFSA has also evaluated it and concluded it is safe at established levels. Some studies have suggested a possible link between synthetic food dyes and hyperactivity in some children, but evidence is mixed and not conclusive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1, from food products.
