What it is

FD&C Red #40 Color is a synthetic dye used to give foods a red color. It is made from petroleum.

Why it's used

Manufacturers add Red #40 to make foods and drinks more visually appealing. It is commonly found in candies, beverages, baked goods, cereals, and some sauces.

Health notes

FD&C Red #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. Some studies have suggested a link between synthetic food dyes, including Red #40, and hyperactivity in some children, but the evidence is mixed and more research is ongoing. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red #40.
