Erythrosine E127 (Red No. 3): BANNED IN US! What You Need to Know

Erythrosine (E127), commonly known as Red No. 3, is a synthetic red dye used in a variety of food products, medications, and cosmetics. While it has been approved for use in many countries, concerns about its safety have led to bans and restrictions in some parts of the world.

Update on 21 Jan 2025this food additive was banned in the US. Read below for more details.

Studies linking Red No. 3 to thyroid tumors in animal research have fueled the debate about its potential health risks. In this article, we’ll explore the uses of erythrosine, the health risks associated with it, and what you can do to avoid it in your diet.

What is Erythrosine (Red No. 3)?

Erythrosine is a bright red, water-soluble synthetic dye derived from coal tar. It is classified as a xanthene dye and is often used to:

  • Add vibrant color to candies, pastries, and beverages.
  • Enhance the appearance of medications and syrups.
  • Color cosmetics such as lipsticks and blushes.

Despite its widespread use, erythrosine has been under scrutiny for decades due to concerns about its impact on human health and the environment.


Why is Erythrosine Controversial?

The controversy surrounding E127 stems from scientific studies that suggest potential health risks. In particular, animal studies have found links between erythrosine and thyroid tumors. These findings have prompted some regulatory bodies to ban or restrict its use in food products. For example:

  • The United States has banned its use in cosmetics but continues to allow it in food and medications.
  • Several countries, including Norway and Finland, have prohibited its use entirely.

Health Risks Associated with Erythrosine E127

1. Thyroid Tumors and Hormonal Disruption

One of the most concerning risks linked to erythrosine is its potential to cause thyroid tumors. Studies conducted on laboratory animals in the 1980s revealed that high doses of E127 could lead to an increased incidence of thyroid cancer. The dye is believed to interfere with thyroid function by disrupting hormone production, which can result in hormonal imbalances. While these effects were observed at doses higher than typical human consumption, the findings have raised red flags about its long-term safety.

2. Hyperactivity and Behavioral Issues

Erythrosine has been associated with behavioral changes, particularly in children. Studies suggest that synthetic dyes, including Red No. 3, may contribute to hyperactivity and attention deficit disorders. This is particularly concerning given its presence in candies, snacks, and beverages that are frequently consumed by children. While more research is needed, many parents choose to avoid products containing E127 to reduce potential behavioral risks.

3. Allergic Reactions and Hypersensitivity

Although rare, some individuals may experience allergic reactions to erythrosine. Symptoms of sensitivity can range from mild skin irritation and itching to more severe respiratory problems. People with pre-existing sensitivities to synthetic dyes or food additives may be at a higher risk.

4. Potential for Carcinogenic Effects

The International Agency for Research on Cancer (IARC) has classified erythrosine as a Group 2B carcinogen, meaning it is “possibly carcinogenic to humans.” This classification is based on limited evidence from animal studies and insufficient human research. While the direct link to cancer in humans remains inconclusive, the classification highlights the need for caution when consuming products containing E127.

5. Oxidative Stress and Cellular Damage

Emerging studies suggest that erythrosine may contribute to oxidative stress, a condition where an imbalance of free radicals and antioxidants damages cells. Oxidative stress has been linked to chronic diseases such as cancer, diabetes, and cardiovascular disorders. While the full extent of this risk is still being studied, it underscores the potential health concerns of long-term exposure to synthetic dyes.

6. Interaction with Medications

Erythrosine is also used in some medications as a colorant, raising concerns about its potential to interact with drugs. Preliminary research suggests that it may affect liver enzyme activity, which can alter the way medications are metabolized. This could lead to unexpected side effects or reduced efficacy of certain drugs, making it particularly concerning for individuals with chronic conditions requiring regular medication.


Regulatory Status of Erythrosine

The regulatory approach to erythrosine varies widely:

  • United States: Recently, the FDA has banned the use of Red No. 3 in foods and dietary supplements due to mounting evidence of its health risks. However, it is still permitted in certain non-food applications, such as some medications.
  • European Union: Permitted with strict limits on acceptable daily intake (ADI).
  • Countries with Bans: Norway, Finland, and others have prohibited its use due to health concerns.

These inconsistencies highlight the ongoing debate about the safety of this additive.


Conclusion: Should You Avoid Erythrosine?

The potential health risks—including its link to thyroid tumors and other adverse effects—make it a controversial ingredient. If you’re looking to reduce artificial additives in your diet or have specific health concerns, avoiding erythrosine may be a wise choice. By choosing natural alternatives and staying informed, you can make healthier decisions for yourself and your family.
