The Controversy That Prompted Change
For years, a key ingredient in Skittles, the food coloring titanium dioxide (TiO2), drew increasing scrutiny from food safety advocates and regulators globally. Used to provide a bright, vibrant, and opaque white base for the candy's colors, TiO2 was deemed 'no longer safe' as a food additive by the European Food Safety Authority (EFSA) in 2021. This conclusion was based on concerns about genotoxicity, or the ability of the substance to potentially damage DNA, although the EFSA could not definitively prove it was a carcinogen. This triggered a major domino effect.
In 2022, a class-action lawsuit was filed in California against Mars, the manufacturer of Skittles, alleging the candy was 'unfit for human consumption' due to the inclusion of titanium dioxide. The lawsuit, though later voluntarily dismissed, brought the issue into the mainstream conversation, pressuring the company to act. Mars had previously pledged to phase out artificial colors in 2016, but TiO2 remained in the U.S. version of Skittles until recently, while the E.U. version was already reformulated.
The Removal of Titanium Dioxide: What Changed?
In late 2024 and confirmed by May 2025, Mars quietly removed titanium dioxide from its U.S. Skittles recipe. This decision followed the 2022 lawsuit and mounting pressure from consumer advocacy groups. While the company stated that the move was made to meet consumer preferences, it directly aligns with international regulatory standards that had already deemed the additive a concern. This change was a significant victory for food safety advocates who had long campaigned against the additive.
- Increased Consumer Awareness: The public controversy surrounding TiO2 raised awareness of ingredients in ultra-processed foods.
- Aligns with E.U. Standards: The removal brings U.S. Skittles closer in line with the formula sold in the European Union, which banned TiO2 as a food additive in 2022.
- State-Level Pressure: Actions in states like California, which passed legislation banning several other additives but debated banning TiO2, signaled a growing regulatory push that major corporations could no longer ignore.
Are Other Additives Still a Concern?
Despite the removal of titanium dioxide, Skittles still contain other artificial colors and ingredients that have drawn criticism. These include dyes like Red 40, Yellow 5, and Yellow 6, which have been linked in some studies to hyperactivity in children, a claim the FDA continues to monitor. While the FDA still considers these dyes safe for consumption within regulated limits, a growing number of consumers and advocates are calling for their removal. The recent FDA decision to ban Red Dye No. 3 by 2027 further highlights the shifting landscape of food additive regulation.
To better understand the differences, here is a comparison of past and present Skittles ingredients, as well as regulatory stances:
| Feature | U.S. Skittles (Pre-2025) | U.S. Skittles (Post-2025) | European Union (EU) Skittles |
|---|---|---|---|
| Titanium Dioxide (TiO2) | Included | Removed | Removed since 2022 |
| Other Artificial Dyes | Red 40, Yellow 5, Yellow 6, Blue 1, etc. | Red 40, Yellow 5, Yellow 6, Blue 1, etc. | Use of some dyes restricted; alternatives often used |
| Sugar Content | High | High | Varies by formulation and market |
| Regulatory Stance (TiO2) | Approved under 1% weight until 2024/2025 removal | Removed following consumer pressure | Banned entirely as a food additive |
| Controversy Level | High due to lawsuits and media attention | Lowered, but other dyes remain a concern | Lower due to removal of controversial ingredients |
Making Informed Choices as a Consumer
While Skittles have addressed one of the most prominent concerns, they remain a high-sugar, highly processed candy containing artificial colors and flavors. Consumers concerned about these ingredients still have options.
- Read Ingredient Labels: The simplest way to be informed is to read the ingredient list on candy packaging. Look for 'titanium dioxide' or 'E171' (the E.U. code), as well as specific artificial color names (e.g., Red 40).
- Seek Out Organic Alternatives: Certified organic foods are prohibited from using titanium dioxide and other synthetic dyes. Many health food stores offer candy alternatives with natural colorings from sources like beet juice or paprika extract.
- Support Regulatory Changes: Many consumer advocacy groups, like the Center for Science in the Public Interest (CSPI), are actively petitioning for further regulatory changes in the U.S. food supply. Consumers can lend their voice by supporting these organizations. As highlighted by Consumer Reports, state-level action has proven effective in pressuring companies to reformulate their products nationwide.
Ultimately, the safety of consuming Skittles has shifted. The removal of titanium dioxide addresses a major concern, particularly around potential genotoxicity. However, for those with sensitivities to other artificial dyes or seeking to minimize processed food intake, the candy is still not without controversy. Being an informed consumer empowers you to decide what is right for your own health.

Conclusion: A Step Toward Reform, But More to Consider
The question of whether Skittles are safe has evolved significantly. While the specific issue of titanium dioxide has been resolved by Mars in the U.S. market, other health-conscious consumers must weigh the continued presence of other synthetic colorings against their dietary preferences. This event serves as a powerful reminder of how consumer pressure and state-level regulation can influence global food corporations. The candy is likely 'safer' than before, but whether it is 'safe' depends on individual sensitivity and dietary philosophy regarding processed foods and artificial ingredients.
