Red #3: The Synthetic Food Dye that Was Finally Banned in 2024
This toxic food dye is no longer legal.
Valentine’s Day is a Hallmark Holiday known for fancy dinners, romance, chocolate, champagne, and…
Red candy.

Okay, quick story.
Scroll down to skip it and read on about Red #3. 👇
Before I met my husband, I hated Valentines Day.
Over the years, I have heard many people lovingly (sarcasm) refer to this ‘very special day’ as Singles’ Awareness Day (S.A.D.).
I was single and alone every Valentine’s Day… except for one year.
That one year, I was dating this guy who was somewhat aimless, kinda reckless in a fun sort of way, and tall like me; I’m 6’0” and he was 6’11”. If you’re a tall woman, you can appreciate my predicament and understand why I put up with the b.s. to have a tall boyfriend.
On that particular V-Day, he took me out to a very nice à la carte steak restaurant to celebrate. When the bill came, he said, “Got your credit card, honey?” 😮
And then, on the way home, we got pulled over for speeding (he was driving). 😠
I was a dumb twentysomething and got out of the car to beg the police officer to give us a break. On the brink of losing my mind, I shared a sob story about how I’m the one who is going to have to pay for the speeding ticket after paying for my own V-Day dinner. 😢
We still got a ticket, but that nice police officer definitely gave us a break.
And yes - I totally dumped that loser.
Okay, enough of that…
Hopefully, you have some happier V-Day stories!
👉 So, let’s get back to the topic.
Why is Red #3 So Bad?
Red #3 is also known as Erythrosine, a synthetic cherry-red dye made from petroleum-based compounds.
Erythrosine: chemical formula C₂₀H₆I₄Na₂O₅
Red #3 was used in many cosmetics (e.g.: blush, lipstick, and mascara) before it was banned in 1990 for cosmetics only.
And, it was used in a wide variety of medications and food products (e.g.: red candy, cough syrup, and children’s allergy medication) until it was banned in 2024 for food products.
The following are just a few of the illnesses, reactions, symptoms, and research findings tied to products containing Red #3:
Thyroid Tumors & Cancer Risks
Animal studies, particularly in rats, have shown that high doses of Red #3 can cause thyroid tumors.
Hyperactivity & Behavioral Issues in Children
Like other artificial dyes, Red #3 has been linked to increased hyperactivity, ADHD symptoms, and learning difficulties in some children.
Allergic Reactions & Sensitivities
Some people experience skin rashes, itching, or headaches after consuming Red #3, similar to reactions seen with other synthetic dyes.
Potential Endocrine Disruption
There are concerns that Red #3 may affect hormone levels by interfering with thyroid function.
Food Intolerance Symptoms
Some individuals report digestive issues, bloating, or discomfort after consuming foods with artificial dyes, such as Red #3.

Why did it take so long to ban Red #3?
For years, despite clear health risks, Red #3 stayed on the market because the U.S. Food and Drug Administration (FDA) required a higher level of proof before pulling it from food.
Consumer advocacy groups, like the Center for Science in the Public Interest (CSPI), had been pushing for a ban for decades, but progress was slow.
It wasn’t until 2024 - after mounting public awareness and legal pressure - that regulators finally took action and banned it from food.

The best thing you can do to protect yourself from the risks of food and cosmetic additives like the ones I mentioned in this article is to Read the Labels.
Especially beware because the Red #3 ban does not mean that all red food dyes are banned. Food producers are switching their ingredients to favor Red #40 as a replacement to Red #3.
