Froot Loops Ingredients: Every Color Explained (2026)

Last reviewed: November 2026. Reflects the U.S. Kellogg’s Froot Loops label (7.9 oz box, ©2025 WK Kellogg Co), photographed November 2026, which still lists four synthetic dyes. WK Kellogg says reformulated boxes colored from natural sources ship to retailers before the end of 2026; check the ingredient list on your box.

Froot Loops is a sweetened multigrain cereal, and the box tells you nearly everything about it in the first two ingredients and the last four. It starts with corn flour and sugar, adds wheat and oat flours, and ends with Red 40, Yellow 5, Blue 1, and Yellow 6, which makes it one of the last major U.S. cereals still colored with synthetic dyes. That’s about to change: in August 2026 WK Kellogg moved its dye-free deadline up a full year and says naturally colored Froot Loops ship to stores before the end of 2026. What won’t change is the 12 grams of added sugar in every bowl. The “natural fruit flavors” on the front are flavors, not fruit; there’s no fruit on the ingredient list. Here’s all the Froot Loops ingredients, what the dyes do and don’t do, and what the new box will and won’t fix.

Quick answer: what’s in Froot Loops?

The full Froot Loops ingredients list

Three things to notice. Sugar is the second ingredient, ahead of the wheat and oat flours, so by weight there’s more sugar in a bowl than either of those grains. The four dyes are the last four ingredients, which tells you how little it takes to make cereal neon: under 2% of the box, doing all of the visual work. And the oil is hydrogenated coconut, soybean, or cottonseed; the label shows 0 g of trans fat, so this is the fully hydrogenated kind, which turns oil into saturated fat rather than the partially hydrogenated trans fat the FDA banned.

Froot Loops ingredients explained

Corn flour blend Fine, part whole grain

Whole grain yellow corn flour plus degerminated corn flour, which has had the germ and bran removed. The blend is why the box can say “multigrain” and count some whole grain; the degerminated half is refined starch.

Sugar Flagged, 12 g

About 3 teaspoons per serving, and the second ingredient. By weight, Froot Loops is roughly 31% added sugar. That’s the same 12 g as Lucky Charms and less than Cap’n Crunch (16 g). The American Heart Association suggests children have less than 25 g of added sugar a day, so one bowl is half of it before the day starts. Our sugar and corn syrup breakdown covers the research on added sugar.

Wheat flour, whole grain oat flour Fine

The other two grains in “multigrain.” The wheat is refined; the oat flour is whole grain. Together with the corn, the box claims 15 g of whole grain per serving.

Modified food starch, maltodextrin Fine

Starches that give the loops their light, puffed texture and help the coating stick. Maltodextrin is a fast-digesting carbohydrate; in a cereal already built on sugar and refined corn, it’s a footnote.

Hydrogenated coconut, soybean and/or cottonseed oil Small amount

Less than 2% of the box, used to coat the loops and keep them crisp in milk. Fully hydrogenated oil contains no trans fat but is saturated; at 0.5 g of saturated fat per serving, it’s not a meaningful amount.

Oat fiber, soluble corn fiber Fine, added fiber

The source of most of the 3 g of fiber that lets the box say “good source of fiber.” Oat fiber is the ground hull of the oat; soluble corn fiber is a processed starch that resists digestion. Both count as fiber on the label and are well tolerated. They’re isolated fibers added to a refined cereal, which is different from fiber that arrives in whole food, but they do count.

Salt 210 mg

9% of the daily value per serving. Moderate for a cereal: less than Cap’n Crunch (290 mg) or Cinnamon Toast Crunch (230 mg).

Natural flavor Undisclosed

The “natural fruit flavors” on the front. The label lists a single natural flavor and no fruit or juice; the different colors don’t come with different flavors in the ingredient list. “Froot” with two o’s is how the brand has always handled it.

Red 40 Flagged

The most-used synthetic dye in American food, and the one behind most of the dye debate. The FDA considers it safe at approved levels; a 2007 study in The Lancet found that mixtures including it increased hyperactivity in some children, which is why the EU requires a warning label on foods that contain it. California has banned it in school food starting December 31, 2027. Our Red 40 breakdown has the full research and the timelines.

Yellow 5, Blue 1, Yellow 6 Flagged

The other three colors. Yellow 5 (tartrazine) causes reactions in a small number of sensitive people and is the other dye most often named in the hyperactivity studies. Yellow 6 carries the same EU warning. Blue 1 has the least concerning record of the four and is mostly flagged because it’s part of the set being phased out. Together they make six loop colors from four dyes. Our synthetic food dyes breakdown covers all nine FD&C colors.

Vitamins and minerals Fine, fortified

Vitamin C, iron, niacin, B6, riboflavin, thiamin, folic acid, D3, and B12, mostly at 20–25% of the daily value. Fortification is genuinely useful, especially the folic acid and iron, and it’s the main nutritional argument for any fortified cereal. It’s also why “9 vitamins & minerals” sits on the front of a box that’s a third sugar.

BHT in the packaging Not in the food

Butylated hydroxytoluene, an antioxidant added to the liner to keep the cereal from going stale, not to the cereal itself. Small amounts can migrate into the food. EFSA reviewed BHT in 2012 and set an acceptable daily intake; animal research is mixed, and it’s on many avoid lists. WK Kellogg says it’s removing BHT from the cereal packaging that still has it, alongside the dyes.

The dye-free Froot Loops: what’s changing and when

WK Kellogg first committed in 2025 to remove FD&C colors from its cereals by the end of 2027, after a Texas Attorney General investigation ended with the company signing an assurance of voluntary compliance. In August 2026 it moved that up a year: production of the reformulated Froot Loops and Apple Jacks begins in late 2026, with boxes shipping to retailers before year-end and reaching most shelves in early 2027. The new colors come from fruit and vegetable juices and other plant sources, and the company says it tested the recipe to keep the same six-color look. Foods it sells to schools were reformulated first, starting January 2026.

The box we photographed in November 2026 is the old formula, and that will be true of much of what’s on shelves for a few months. Look for the dyes at the end of the ingredient list: if you see Red 40, Yellow 5, Blue 1, and Yellow 6, it’s the old box. Canadian Froot Loops have long been colored without synthetic dyes, which is part of why the U.S. version drew so much pressure.

What a dye-free box fixes is the dye question, and only that. The sugar, the refined starch, the sodium, and the 2 g of protein stay where they are. A dye-free Froot Loops is a better version of the same sweetened cereal, not a healthy one.

The front-of-box claims, checked

“Good source of fiber”: true. 3 g is 11% of the daily value, which meets the FDA’s 10% threshold, and it comes mostly from added oat fiber and soluble corn fiber. “15 g whole grains”: true, from the whole grain corn and oat flours; the dietary guidelines suggest at least 48 g a day. “9 vitamins & minerals”: true, all from fortification. “Natural fruit flavors”: the flavor is natural; there’s no fruit. None of these claims is false. Each is technically accurate on a box that’s 31% added sugar.

Froot Loops vs. other kids’ cereals

All three from the boxes we photographed in November 2026. “Sugar by weight” is added sugar divided by serving weight, which evens out the different serving sizes. Our Lucky Charms breakdown has the same 12 g of added sugar per serving and switched to colors from natural sources in 2026.

Are Froot Loops bad for you?

The concerns, ranked by evidence:

1. Added sugar. 12 g per serving, about 31% of the cereal by weight; the most consistent long-term concern with sweetened cereals.
2. Synthetic dyes (current box). Red 40, Yellow 5, Blue 1, Yellow 6; linked to hyperactivity in some sensitive children, being replaced by the end of 2026.
3. Low protein and refined starch. 2 g of protein in 150 calories; it won’t hold a kid until lunch on its own.
4. Sodium. 210 mg; moderate, adds up with the rest of the day.
5. BHT in the liner. Low exposure, being removed.

Froot Loops for kids, allergies, and diets

Kids: the audience the box is designed for, and the reason the dye change matters. If your child is sensitive to dyes, either wait for the new box or read the ingredient list before buying. A smaller bowl with milk and fruit is the better pattern than a full serving on its own.

Allergies: contains wheat, and that is the only allergen statement on the box we read. Not gluten-free.

Vegan: the ingredient list has no animal ingredients. Vitamin D3 is often animal-derived, and the box doesn’t say which source, so strict vegans may want to check with the company.

Cleaner alternatives

For the same bowl with less sugar: plain Cheerios or another low-sugar O-shaped cereal, sweetened with sliced strawberries or blueberries, which also gives real fruit color. For a kid who wants the bright loops: a mix of half Froot Loops and half plain O’s cuts the sugar and dyes in half without a fight. For dye-free now: Cinnamon Toast Crunch has never used synthetic dyes and has whole wheat first, though it has the same 12 g of added sugar. And once the new boxes reach your store, the dye-free Froot Loops is the straightforward swap for this one.
