What it is

FD&C Red No. 40, also known as Allura Red AC, is a synthetic food coloring. It is a brilliant red dye that is manufactured from petroleum.

Why it's used

Manufacturers add Red No. 40 to provide a red color to foods and beverages. It is commonly found in candies, cereals, snack foods, soft drinks, and baked goods.

Health notes

FD&C Red No. 40 is an FDA-approved color additive for use in food. JECFA has evaluated it and set an acceptable daily intake. EFSA has also evaluated this additive. There has been ongoing discussion and some studies suggesting a link between synthetic food dyes, including Red No. 40, and hyperactivity in some children, particularly those who are sensitive to them; however, evidence remains mixed. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red No. 40.
