Magic Spoon Fruity Grain-Free Cereal: 13g Protein per Cup, Labelgrade B+ (80/100)
B+ 80 / 100 — The highest-protein-density cereal on the US market (34g per 100g of dry cereal), achieved by replacing the grain base with milk protein isolate and tapioca starch. Zero sugar (allulose + monk fruit). Trade-offs: it's a high-priced engineered product with a 10-ingredient list, not a whole-food cereal.

Magic Spoon Fruity packs 13 g of protein and 0 g of sugar into a ~1 cup (38 g) serving for 150 calories (USDA FDC 2374897) — and it does it without a single grain. That’s the whole trick: where a normal fruity cereal starts with corn or rice flour, Magic Spoon starts with a milk protein blend (casein + whey protein concentrate) listed first by weight, binds it with tapioca starch, and sweetens it with allulose and monk fruit instead of sugar. The result is 34 g of protein per 100 g of dry cereal, the highest density in the cereal category we grade. It lands at Labelgrade B+ (80/100): a maxed-out protein score and a perfect sugar score, dragged down by sodium and the reality that this is a 10-ingredient engineered food, not oats.
Why the B+
| Dimension | Grade | Score | Why |
|---|---|---|---|
| Protein density | A+ | 100 / 100 | 34 g per 100 g — pinned at the formula ceiling, the densest cereal we’ve graded |
| Sugar load | A+ | 100 / 100 | 0 g sugar; allulose and monk fruit aren’t counted as sugar under FDA rules |
| Saturated fat load | B+ | 83 / 100 | 1 g per serving from the sunflower/avocado oil blend — modest, mostly unsaturated |
| Ingredient quality | B | 75 / 100 | 10 ingredients, no artificial colors or flavors, but milk-protein blend + tapioca starch read as processed-food markers |
| Fiber | D | 48 / 100 | 1 g per serving — this cereal is built around protein, not fiber |
| Sodium load | D | 53 / 100 | ~421 mg per 100 g — high for a dry breakfast food; the weakest dimension |
Two honest reads on this card. The protein A+ is real and rare — almost nothing outside protein powder hits 34 g per 100 g. But the B+ overall is held back by a genuine pairing of weaknesses, not a rounding quirk: a D on fiber and a D on sodium. The fiber D is a design choice (Magic Spoon spends its formula on protein, and the lone gram of fiber comes from a trace of inulin), while the sodium D is the one a daily eater should actually weigh — 160 mg looks trivial until you pour a real two-cup bowl and land near 320 mg before the milk.
What you’re actually eating
Read the panel and the “cereal” framing gets honest fast. The first ingredient is casein + whey protein concentrate — not isolate, concentrate, which is why a little residual lactose is in play — and it’s there for structure, not just macros. The crunch you’d normally get from a puffed grain instead comes from tapioca starch plus an oil blend of high-oleic sunflower and avocado oil, and that oil is where the 8 g of fat lives. The fruity color isn’t Red 40; it’s turmeric, spirulina, and vegetable juice. None of that is bad, but it’s why Labelgrade calls this engineered rather than whole-food: every job a grain used to do has been reassigned to an isolated ingredient. The payoff is that you can eat a bowl that tastes like a nostalgic kids’ cereal and walk away with 13 g of protein and zero sugar — a trade a box of corn-based fruit loops simply can’t offer.
The sweetener, and whether it’s “keto”
The zero on the sugar line is doing a lot of work, so it’s worth being precise. Magic Spoon is sweetened with allulose and monk fruit extract, neither of which counts as sugar under FDA labeling. Allulose is the interesting one: it’s a rare sugar the body absorbs but doesn’t metabolize like glucose, so it tastes like sugar with effectively no calories and near-zero blood-glucose response, and the FDA exempts it from net-carb math. That’s why a serving can show 15 g total carbs yet behave like a low-net-carb food — most of those carbs are the allulose itself. For practical keto that’s a pass; for strict carb-counters who tally allulose anyway, run your own number. The one caveat is tolerance: large allulose doses can cause GI upset, but a single 38 g serving is well under the level where that tends to show up.
How it compares
| Product | Protein / serving | Protein / 100 g | Fiber | Sugar | Sweetener base | Labelgrade |
|---|---|---|---|---|---|---|
| Magic Spoon Fruity (this product) | 13 g (38 g) | 34 g | 1 g | 0 g | Allulose + monk fruit | B+ (80) |
| Catalina Crunch Chocolate Banana | 11 g (36 g) | 31 g | 9 g | 0 g | Stevia + monk fruit | A- (85) |
| Three Wishes Cocoa | 8 g (35 g) | 23 g | 4 g | 3 g | Cane sugar + monk fruit | A- (85) |
This table is the useful part of the decision. Magic Spoon wins protein density outright and is the only one of the three built on milk protein rather than a plant base (Catalina is pea-protein; Three Wishes is chickpea + pea) — so it’s the densest but the only one that’s off-limits to vegans and milk-allergic eaters. Yet both rivals out-grade it. Catalina Crunch beats it on fiber by a mile (9 g vs 1 g) at the same 0 g sugar, which is most of why it earns an A-. Three Wishes carries 3 g of cane sugar and less protein, but its 8-ingredient list is the simplest of the three, which is why kid-focused shoppers gravitate to it. Pick Magic Spoon for the highest protein and the most authentic sugary-cereal taste; pick Catalina if fiber and a vegan base matter more than peak protein.

Frequently Asked Questions
How much protein is in Magic Spoon Fruity, and where does it come from?
13 g per ~1 cup (38 g) serving — 34 g per 100 g of dry cereal (USDA FDC 2374897), the highest protein density we've recorded in the cereal category. It's the first ingredient by weight: a milk protein blend of casein and whey protein concentrate. There is no grain and no wheat/soy protein doing the work, which is what separates it from grain-plus-added-protein cereals like Special K Protein.
If there's no grain, what holds a cup of Magic Spoon together?
Three things stand in for the grain: the casein + whey blend gives the pieces body, tapioca starch binds them, and the oil blend (high-oleic sunflower + avocado) creates the crunch and carries most of the 8 g of fat. Sweetness is allulose + monk fruit; the fruity color is turmeric, spirulina, and vegetable juice rather than artificial dye. Ten ingredients, no synthetic colors or flavors — engineered, but legibly so.
Is it actually keto?
Close enough for most people. A serving is 15 g total carbs and 1 g fiber, but the bulk of those carbs is allulose, which the FDA excludes from net-carb math because the body absorbs it without metabolizing it as sugar. That leaves a low-single-digit net-carb figure per bowl. Strict keto practitioners who count allulose differently should run their own numbers; the 0 g sugar is not in dispute.
Why is the sodium graded a D when 160 mg sounds small?
Labelgrade scores sodium per 100 g, and at 38 g per serving Magic Spoon works out to ~421 mg per 100 g — high for a dry breakfast food. The per-serving 160 mg is only ~7% of the 2,300 mg daily limit, but it climbs fast: a realistic two-cup bowl is ~320 mg before you add anything, and the milk you pour on adds more. It's the single weakest dimension on the card.
Can I eat this if I'm lactose intolerant or have a milk allergy?
These are two different questions. Casein and whey concentrate carry a little residual lactose (small, likely under a gram per serving), so most lactose-intolerant people tolerate a bowl fine — test your own threshold. A milk-protein allergy is a hard no: the protein in this cereal IS milk protein, so there's no safe serving.
How does Magic Spoon Fruity compare to Catalina Crunch and Three Wishes?
Magic Spoon is the densest of the three — 34 g protein per 100 g vs Catalina's 31 g and Three Wishes' 23 g. But Catalina (A-, 85) and Three Wishes (A-, 85) both out-grade it overall, because Catalina brings 9 g of fiber and Three Wishes keeps a shorter ingredient list. Magic Spoon wins on raw protein and milk-protein taste; Catalina wins on fiber; Three Wishes is the gentlest formula for kids.
Whey-and-casein cereal — is this a good post-workout option?
Workable, not optimized. The 13 g does pair fast whey concentrate with slow casein, which is a sensible recovery mix, but you're paying 150 calories and 8 g of fat to get it. A scoop of whey in plain Greek yogurt delivers more protein at fewer calories. Where Magic Spoon wins is the moment it's actually for: a breakfast that tastes like fruity kids' cereal and still books 13 g of protein with no sugar.
