What it is
Red 40 is a synthetic red food dye made from petroleum. It is one of the most widely used food colorings in the United States.
Why it's used
Manufacturers add Red 40 to provide a vibrant red color to foods and beverages. It is commonly found in baked goods, candies, cereals, drinks, and dessert toppings.
Health notes
The U.S. Food and Drug Administration (FDA) permits Red 40 as a color additive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40. Some studies have suggested a possible link between certain artificial food dyes, including Red 40, and increased hyperactivity in children, though the evidence is mixed and not conclusive. Regulatory bodies like the European Food Safety Authority (EFSA) have also evaluated artificial food colors.
Allergen info
Not a major allergen. Red 40 is not derived from any of the nine FDA major allergens and does not contain gluten.
