What it is
FD&C Red 40 is a synthetic red food dye. It is produced from petroleum sources.
Why it's used
Manufacturers add FD&C Red 40 to give foods and beverages a red color. It is commonly used in candies, soft drinks, desserts, and some processed snacks.
Health notes
FD&C Red 40 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. Some studies have suggested a link between synthetic food dyes, including Red 40, and hyperactivity in some children, but the evidence is mixed, and the FDA states that for most children, there is no proven link. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40.
