And FD&C Blue #1

FD&C Blue #1, also known as Brilliant Blue FCF, is a synthetic organic compound used as a food coloring. It is manufactured through chemical synthesis, not derived from natural sources.

Manufacturers add FD&C Blue #1 to give foods and beverages a bright blue color. It is commonly found in candies, soft drinks, ice cream, and other processed foods where a blue hue is desired.

FD&C Blue #1 is an FDA-approved color additive for use in food, drugs, and cosmetics. JECFA has evaluated it and set an acceptable daily intake. EFSA has also evaluated it and set an acceptable daily intake. While generally considered safe at typical intake levels, some studies have suggested a possible link between synthetic food dyes, including Blue #1, and hyperactivity in some children; however, the 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.
