How to choose
Want the highest protein per bowl? TRUELY leads at up to 18 g per cup, with Magic Spoon close behind at ~13 g. Want zero sugar and the most nostalgic taste? Magic Spoon is the gold standard. Topping yogurt or want crunch? Pick a granola — Magic Spoon for more protein, Prozis for the lowest price. Trying a brand for the first time? Start with a TRUELY single cup before buying a full box. Everything here is grain-free, gluten-free and keto/low-carb friendly, so the main trade-offs are protein, price and texture rather than diet fit.
FAQ

What is the difference between protein cereal and protein granola? Protein cereal is a light, milk-friendly cereal you eat in a bowl, while protein granola is a denser, crunchy clustered topping that's also great over yogurt or eaten by the handful.
