If you’re becoming more aware of the ingredients in the foods and drinks you consume, you’ve probably run into Red Dye 40 at some point. This artificial coloring gives many soft drinks their vibrant hue, and Allura Red AC (its technical name) shows up on more ingredient labels than most people realize. It’s one of the most common colorants approved for use in the United States. That’s exactly why so many shoppers want a clear, straightforward answer instead of decoding a chemistry label at the grocery store. Below, we cover which soft drinks contain it, the potential health concerns behind it, and what to reach for if you’d rather avoid it.

Which Soft Drinks Contain Red Dye 40
Not every cherry or strawberry-flavored drink on the shelf relies on it — some brands have already reformulated with plant-based colorants, while others still list it plainly on the nutrition panel. The table below breaks down some of the most recognizable names, plus a few less obvious ones worth knowing about.
| Brand | Flavor / Type | Contains It? |
|---|---|---|
| Mountain Dew Code Red | Cherry-citrus | Yes |
| Fanta Strawberry | Strawberry | Yes |
| Big Red | Cream soda-style | Yes |
| Cherry Coke | Cherry cola | Yes (regular Coke does not) |
| Pepsi Wild Cherry | Cherry cola | Yes |
| Crush Cherry | Cherry | Yes |
| Sunkist Cherry Limeade | Cherry-lime | Yes |
| Faygo Redpop | Cream soda-style | Yes |
| Dr Pepper (original) | Cola-style | No |
A common question is whether the two biggest cola brands use it. Regular Coke and regular Pepsi don’t contain this colorant — it’s specifically the cherry, strawberry, and cream-soda variations of these product lines that typically do.
Red Dye 40 in Cream Sodas and Flavored Variants
Cream soda is one of the categories where this red dye shows up most consistently. Big Red, one of the most iconic cream-soda-style drinks on U.S. shelves, gets its signature color almost entirely from red dye 40, and there’s currently no widely available reformulated version on the market. Faygo’s Redpop follows the same formula. If you’re trying to cut this additive out of your cream soda habit, always check the label on any red-tinted cream soda. The color itself is a strong tell that the dye is likely present.
Orange cream soda flavors are a different story — most rely on Yellow 5 and Yellow 6 rather than red dye 40, since there’s no rosy tone to replicate. Black cherry cream soda, on the other hand, almost always uses red dye 40. Some brands blend in a small amount of blue dye to achieve the deeper, darker cherry tone. It’s worth treating black cherry and standard cherry cream sodas the same way when scanning labels.
How to Check Labels for Color Additives
The easiest way to confirm whether a specific drink contains this additive is to read the ingredients list rather than guess from the color alone. On U.S. packaging, it’s usually listed as “Red 40” or “this synthetic dye’s” formal name; in other countries you may see the number E129 instead. Ingredient-labeling rules require brands to name any color additive explicitly on food labels, so a quick label check is more reliable than color alone — some naturally-colored drinks look just as vivid. If you’re comparing several brands side by side, it’s worth checking a few flavor variants within the same product line too, since a company will sometimes reformulate one flavor while leaving another unchanged.
Reading food labels gets easier with practice: color additives are almost always grouped together near the end of the ingredients list, right after preservatives and before vitamins or minerals. If a label lists more than one color additive, that’s usually a sign the drink is aiming for a specific, hard-to-replicate shade using a blend rather than a single dye.
Why Manufacturers Use This Colorant in Soft Drinks
Color plays a bigger role in how we perceive flavor than most consumers assume — a cherry drink that looks pale or washed-out tends to taste “wrong” to most people even if the flavor recipe is identical. Manufacturers reach for synthetic colorants like this one because they’re inexpensive, stable under light and heat, and give a consistent shade batch after batch. That consistency is harder to guarantee with natural pigments, which can fade or vary with each harvest. This reflects a much broader pattern across the food industry. Manufacturers use artificial colors and other lab-made dyes in everything from candy to cereal to condiments, not just carbonated drinks. These dyes extend shelf life, keep production costs down, and offer a wide variety of vibrant, reliable shades.
Natural Dyes vs. Synthetic Food Dyes
Not all food dyes are created the same way. Natural food dyes, like beet juice or carmine, come from plant or insect sources and can vary slightly from batch to batch. Manufacturers make synthetic food dyes, including red dye 40, in a lab to an exact chemical specification. That’s why two bottles of the same product almost always look identical, no matter where or when the company made them. Artificial dyes as a category tend to resist fading from light exposure better than natural alternatives. That’s part of why they remain so common in beverages that sit on store shelves for months at a time.
Potential Health Risks
Though the Food and Drug Administration (FDA) has approved Red Dye 40 for use in food and drink, it remains one of the more scrutinized food additives on the market. Some studies point to allergic-type reactions in sensitive individuals, and there’s an ongoing conversation about behavioral effects in children, though the science isn’t settled either way.
Allergic Reactions
For some people, consuming products with this colorant can trigger hives, swelling, or difficulty breathing. If you notice these symptoms after having a product that lists this dye, it’s worth speaking with a healthcare professional and keeping a note of which products triggered the reaction.
ADHD, Hyperactivity, and Behavioral Effects in Children
There’s ongoing debate over whether this colorant, along with other synthetic dyes, contributes to hyperactivity or ADHD-like symptoms in children. Some parents and pediatric researchers report noticeable behavior changes tied to synthetic additives and preservatives, though controlled studies on ADHD specifically show mixed results. Because of this uncertainty, some pediatric guidelines suggest limiting these additives for children who seem sensitive to them, even without a confirmed ADHD diagnosis. Several advocacy groups have also pushed for more research into the link between food dyes and attention-related symptoms.
Food Additives and Long-Term Safety Questions
Beyond allergies and behavior, some consumer groups have raised broader questions about food additives and long-term safety, including cancer risk. Current research on red dye 40 itself hasn’t established a direct cancer link at approved usage levels. Still, the conversation around food additives as a category — including some other dyes and preservatives — keeps evolving as researchers publish new studies.
Is This Colorant Banned Anywhere?
It’s legal in the United States and approved by the FDA, but that hasn’t stopped growing scrutiny elsewhere. The European Union requires a warning label on products containing it, noting it may have an adverse effect on activity and attention in children, which has pushed many EU manufacturers to reformulate rather than carry the label. Norway and a few other countries went further decades ago, restricting several synthetic colorants outright in everyday grocery items. California’s Food Safety Act has also targeted several of these dyes in products marketed to children, and a handful of U.S. school districts have restricted it independently of federal rules. None of this amounts to an outright nationwide ban in the U.S. But the regulatory gap between regions is part of why the ingredient draws so much attention — and it’s a gap that could narrow further as more states consider similar legislation.
Where Else This Colorant Shows Up
Carbonated drinks aren’t the only place this colorant turns up — it’s one of the most widely used food dyes in the American supply chain. You’ll also find it in flavored drink powders, candy and gummies, breakfast cereals, flavored yogurts, boxed cake mixes and frostings, gelatin desserts, and even some medications or vitamin supplements marketed to children.
Color Additives in Candy, Cereal, and Packaged Snacks
Some products lean on mineral-based color additives instead, like iron oxide, which the FDA regulates under a separate set of rules. A full list of foods with this additive would run into the hundreds of items across the packaged-foods aisle. That’s exactly why reading the ingredient label has become second nature for shoppers trying to manage their family’s overall intake. Other red dyes, like Red 3, show up in some of the same product categories and are worth watching for as well. The FDA has flagged several synthetic dyes over the years, since regulations around them evolve on a separate track.
Better-for-You Soft Drink Options
If you’d rather steer clear of this ingredient, you have more options today than ever. Here are a few directions worth exploring:
Plant-Based Colorings
A growing number of manufacturers now color their drinks with plant-based pigments instead of lab-made ones. Look for labels that mention carmine — an ingredient that already shows up across a wide range of everyday foods — beet juice, or annatto rather than a numbered dye. Oil-based natural colorings, increasingly popular in chocolate, candy, and sauces, are another option gaining traction. These ingredients achieve a similar rosy or pink tone without the synthetic additive.
Clear or Light-Colored Options
Choosing a clear or lighter-colored drink is one of the simplest ways to cut back on artificial colorants altogether. Lemon-lime drinks, ginger ales, and plain club soda are generally free of this additive, since there’s no rosy or pink shade to replicate.
Homemade Beverages
Making your own soda or flavored water at home puts you in full control of what goes in. Fresh-pressed fruit, herbal teas, or a splash of sparkling water with muddled berries can deliver color and flavor without any artificial additives at all.
Sodas and Beverages Without Red Dye 40
Building a shopping list of sodas and other beverages that skip this dye entirely? Start with the basics: regular Coke, regular Pepsi, most root beers, and plain sparkling waters are typically free of it. Beyond soda, sparkling juices and many sports drinks now advertise “no artificial dyes” directly on the front label. That makes comparison shopping faster than digging through the fine print every time.
Which Soft Drinks Are Not Recommended for Consumption in 2025 and Why?
Beyond the presence of any single colorant, several mainstream soft drinks carry a broader mix of ingredients worth thinking twice about — high sugar loads, artificial sweeteners, or preservatives with their own separate track record of scrutiny.
- Mountain Dew: Contains high sugar levels (77 grams per 20 oz serving) and Yellow 5, linked to hyperactivity concerns.
- Cola (regular): Has around 65 grams of sugar per serving, increasing the risk of obesity, type 2 diabetes, and dental cavities.
- Pepsi: Similar sugar profile to other colas, with 69 grams of sugar per 20 oz serving, and includes phosphoric acid, which impacts bone health.
- Dr Pepper Cream Soda: Contains Caramel Color IV, linked to cancer risks, and high fructose corn syrup, promoting obesity and metabolic issues.
- Fanta (various flavors): High in sugar and artificial colorants like Yellow 6, which may cause allergic reactions in sensitive individuals.
- Diet colas: Use aspartame, an artificial sweetener associated with potential negative effects on gut microbiota and neurological risks.
- Sprite: While caffeine-free, it contains 56 grams of sugar per 12 oz can, making it less healthy than other drink options.
Making Informed Choices
Knowing which soft drinks rely on this colorant — and which don’t — puts the decision back in your hands. It’s an approved additive, not a banned one, but that doesn’t mean every household needs to treat it the same way. Check food labels, look into plant-based alternatives when they’re available, and talk to a healthcare professional if you or your kids seem sensitive to synthetic additives. None of this requires overhauling your entire pantry overnight — small, label-conscious swaps add up over time. Staying informed is really the whole game here, and it lets you keep enjoying your favorite drinks with a bit more confidence.
FAQs about Red Dye 40
1. Does Dr Pepper have Red Dye 40 in all its versions?
No, not all versions of Dr Pepper contain it. Some flavored variants like Cherry or limited editions may include it, but the original typically doesn’t. Always check the label.
2. Can it cause hyperactivity in adults too?
Most studies focus on children, but some adults report mood changes or sensitivity to synthetic colorants too, though evidence here is still inconclusive.
3. Are there caffeine-free drinks that still contain Red Dye 40?
Yes. Some caffeine-free fruit-flavored drinks, such as certain strawberry or cherry varieties, use it for color even without any caffeine.
4. Do zero-sugar versions also use it?
Yes. Many diet or zero-sugar versions, like Diet Cherry Coke or Pepsi Zero Wild Cherry, may still contain it for visual appeal.
More Common Questions
5. Is Red Dye 40 harmful during pregnancy?
There’s no definitive proof of harm, but some health professionals advise pregnant women to limit artificial additives generally, due to possible allergic reactions or sensitivities.
6. Do energy drinks contain Red Dye 40 too?
Yes, several energy drinks — especially the bright or cherry-toned ones — use it or similar colorants to enhance visual appeal. Always check the ingredients.
7. What does Red Dye 40 do to your body?
Once consumed, it’s absorbed and metabolized like other food additives, with most of it passing through the digestive system. It has no known nutritional function — its only role is visual — which is part of why some people choose to limit it even in the absence of a personal sensitivity.
8. Why is Red 40 banned in some countries but not others?
It isn’t outright banned in most places, but regulatory bodies weigh the same safety data differently. The EU requires a warning label rather than a ban, while a few countries have restricted several synthetic dyes as a category rather than targeting this one specifically.
9. What are the main foods and drinks to avoid if I’m cutting out Red 40?
Beyond cherry and strawberry sodas, watch for candy, fruit snacks, flavored cereals, gelatin desserts, and some flavored yogurts or drink mixes — reading the ingredients list is still the most reliable check across all of these categories.
Other questions to answer
10. What soda has no Red Dye 40?
Regular Coke, regular Pepsi, and most clear or lemon-lime drinks like Sprite and 7UP are typically free of it, since they don’t rely on that cherry or pink hue.
11. What brands use Red 40?
Beyond soft drinks, brands across candy, cereal, and drink-mix categories use it too — checking the ingredients panel is the only reliable way to confirm any single product.
12. How can I filter out products with Red 40 when shopping online?
Look for ingredient lists on product pages, or use search filters for “natural coloring” or “dye-free.” Some health-focused retailers offer options free of it entirely.
13. What does Red Dye 40 taste like?
It has no flavor of its own. It only adds visual appeal and doesn’t alter taste directly, though color can influence how people perceive sweetness or flavor.
