November 29, 2025 •

2 min read

According to The Hershey Company, as of 2021, Twizzlers do not contain the now-banned Red Dye 3, a food additive linked to cancer in lab rats. Instead, the red licorice-style candy contains the synthetic color additive Red 40.

Quick Summary

Twizzlers use the artificial color Red 40, not the recently banned Red Dye 3. While Red 40 is still legal nationwide, it faces increasing scrutiny and is scheduled to be phased out by The Hershey Company by the end of 2027.

Key Points

Does not contain Red Dye 3: Twizzlers do not include the now-banned Red Dye 3, which was removed from food products due to cancer concerns.
Contains Red Dye 40: Twizzlers currently use the synthetic color additive Red 40, which is still approved by the FDA but faces increasing scrutiny.
Hershey is phasing out synthetic dyes: The Hershey Company, Twizzlers' parent, has announced plans to remove all synthetic food dyes, including Red 40, by the end of 2027.
Red 40 and hyperactivity: Some research links Red 40 to hyperactivity in children, particularly in sensitive individuals, though not everyone is affected.
Natural dye alternatives exist: Manufacturers are increasingly using plant-based alternatives like beet juice and paprika extract to color products naturally.
Always check the ingredients: For those looking to avoid artificial dyes, checking the product label for 'Artificial Color (Red 40)' is the only way to be sure.

Understanding the 'Bad' Red Dyes

When people refer to the "bad red dye," they are typically referring to Red Dye 3 (erythrosine), an additive that the U.S. Food and Drug Administration (FDA) banned for use in food in January 2025 due to evidence linking it to cancer in lab rats. In contrast, the most common synthetic red dye currently in use is Red 40 (Allura Red AC), which is the coloring agent found in Twizzlers. While Red 40 has not been banned outright nationwide, it faces increasing scrutiny from consumers and regulators due to research suggesting potential health concerns.

The Controversial Red Dye 40 in Twizzlers

As an ingredient, Red 40 is derived from petroleum and is used to create a bright, vibrant red color in many processed foods and drinks. The Environmental Working Group (EWG) lists Red 40 as a food additive of "moderate concern". In response to growing consumer demand for more natural ingredients and emerging state-level restrictions, The Hershey Company has announced plans to phase out synthetic food dyes from its U.S. products, including Twizzlers, by the end of 2027.

Potential Health Concerns Associated with Red 40

Studies have suggested a potential link between the consumption of some food dyes, including Red 40, and increased hyperactivity in some children.
Some people may experience allergic reactions to Red 40, ranging from skin rashes to more severe symptoms.
Animal studies have raised concerns about Red 40's effect on gut health.
Research on human cells exposed to Red 40 has shown signs of DNA damage, and some synthetic dyes can be contaminated with carcinogens.

Comparing Red Dye 40 and Red Dye 3

Regulatory Status (US)	Currently approved for food use nationwide, but under review. The Hershey Company plans to remove by 2027.	Banned by the FDA in January 2025 for use in food.
Chemical Origin	Petroleum-based synthetic dye.	Petroleum-based synthetic dye.
Key Concern	Potential link to hyperactivity in sensitive children; some studies suggest inflammatory and DNA-damaging effects.	Historically linked to thyroid cancer in lab rats; already banned in cosmetics since 1990.
Used in Twizzlers?	Yes, currently contains Red 40.	No, does not contain Red Dye 3.
Use in Other Candies	Used widely in many candies, cereals, and beverages.	Was formerly used in some candies like cherry M&M's and some frostings.

The Shift Toward Natural Dyes

Many companies are exploring alternative, plant-based colorings, and Hershey is on track to replace synthetic dyes with natural options by 2027. These alternatives include beet juice, paprika extract, and annatto. This move is driven by consumer pressure, health concerns, and evolving regulations.

Conclusion: A Clear Distinction

Twizzlers contain the controversial Red 40 but not the recently banned Red Dye 3. The debate around Red 40 has led The Hershey Company to commit to its removal in the coming years. Consumers concerned about artificial dyes should check ingredient labels. The shift towards natural alternatives suggests a future with more dye-free candy options.

The safety of Red Dye 40 is a subject of debate. While the FDA considers it safe in small amounts, some studies have linked it to hyperactivity in certain children and potential inflammatory effects in animal studies.

No, Red Dye 40 is not currently banned nationwide in the U.S., though some state-level restrictions and public health concerns are pushing for change. The FDA announced a plan in April 2025 to phase out petroleum-based synthetic dyes, including Red 40, by the end of 2026.

No, The Hershey Company has committed to removing all synthetic dyes from its U.S. products, including Twizzlers, by the end of 2027, transitioning instead to natural colorings.

Yes, many food manufacturers are shifting toward natural color alternatives derived from fruits and vegetables. Examples include beet juice, paprika extract, and annatto.

To find dye-free candies, look for products that specifically state 'dye-free' or check the ingredients list for artificial color additives like 'Artificial Color (Red 40)' or 'FD&C Red No. 40.' Many specialty health food stores and online retailers offer a wide selection of natural candy options.
