The catch

The 0g sugar label leans on 5g of allulose that the FDA does not count as sugar, and at about 10 dollars a box it runs roughly 2 dollars per serving. (source)

The honest take

Magic Spoon Peanut Butter is a grain free cereal built around a milk protein blend, so one 36g cup delivers 14g of complete protein with 0g of added sugar and just 4g net carbs. The sweetness comes from allulose and monk fruit instead of cane sugar, which barely moves blood sugar, and that is the real reason low carb and keto eaters reach for it. The honest flip side is that this is an ultra processed cereal made from isolated proteins, starches and oils rather than whole grains, and at roughly 10 dollars a box you pay about 2 dollars per serving. It earns its spot as a high protein treat swap, not as a whole food breakfast.

Who it's for

✓ Buy it if

Low carb and keto eaters who want a high protein, zero added sugar cereal and do not mind ultra processed ingredients.

Skip if you are dairy free or vegan since it is built on milk protein, or if you want a whole grain breakfast rather than one made from isolated proteins and oils.
