Cereal is one of those nostalgic comfort foods that most of us grew up loving—and, if you’re anything like me, you still enjoy it. The good news? Thanks to advancements in food science, you can now find protein-packed cereals that taste great and support your nutrition goals.
In this review, I’m breaking down 12 of the most popular protein cereals on the market in 2025. I’ll cover:
- Macros: Do they pass the “Protein Test”?
- Ingredients: Clean or questionable?
- Taste: The real deciding factor.
Let’s get into it.
What’s the “Protein Test”?
Take the number of grams of protein and add a zero to it. If the cereal has that number of calories or fewer, it passes. For example: 18g of protein → ≤180 calories.
1. Ghost Protein Cereal
- Calories: 170
- Protein: 18g ✅ Passes the protein test
- Fiber: 1g
- Protein Source: Milk concentrate (bioavailable)
- Sweetener: Sucralose
- Seed Oil: Yes
Taste: Phenomenal. Really close to classic cereal, especially the peanut butter flavor. A bit soft at the end but otherwise excellent.
✅ Verdict: Great taste. Great macros. Recommend.
2. Catalina Crunch
- Calories: 110
- Protein: 11g ✅
- Fiber: 9g
- Fat: 5g (4g from seed oil)
- Protein Source: Plant-based
Taste: Very good, though slightly less sweet than Ghost. Slight aftertaste (erythritol), which some find metallic.
✅ Verdict: Amazing macros. Good taste. Solid option.
3. Magic Spoon
- Calories: 140
- Protein: 13g ❌
- Fiber: 2g
- Protein Source: Milk protein blend
- Fat Source: Avocado & sunflower oil
Taste: Chocolate flavor was bland and disappointing.
❌ Verdict: Not worth it. Macros aren’t great, and taste doesn’t deliver.
4. Three Wishes
- Calories: 130
- Protein: 8g ❌
- Fiber: 3g
- Protein Source: Pea protein
- Ingredients: Very clean—chickpea, tapioca, monk fruit
Taste: Marshmallow flavor nailed it. Better than Magic Spoon.
⚠️ Verdict: Tastes great, but the macros just don’t cut it.
5. Legion
- Calories: 170
- Protein: 17g ✅
- Fiber: 7g
- Fat: 6g saturated
- Price: ~$10/box
Taste: Chocolate was underwhelming for the price.

6. Truly
- Calories: 170
- Protein: 18g ✅
- Fiber: 5g
- Saturated Fat: 2g
- Ingredients: Very clean
Taste: Chocolate peanut butter was delicious. Not quite as tasty as Ghost, but still top tier.
✅ Verdict: Best all-around macros and ingredients. One of the top picks.
7. Premier Protein Cereal
- Calories: 180
- Protein: 20g ✅
- Fiber: 2g
