What it is

Blue 1, also known as Brilliant Blue FCF, is a synthetic food coloring. It is produced from petroleum and gives foods a bright blue hue.

Why it's used

Manufacturers add Blue 1 to give a blue color to various food products. It is commonly found in candies, soft drinks, and some dietary supplements.

Health notes

Blue 1 is an FDA-approved food additive for use in the United States. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated Blue 1 and set an acceptable daily intake. EFSA (the European Food Safety Authority) has also evaluated it. Some studies have suggested a possible link between synthetic food dyes, including Blue 1, and hyperactivity in some children, while other studies have not found a consistent link.

Allergen info

Blue 1 is not a major allergen.
