Really good cereal just has a strong protein taste

7 days ago
This cereal was pretty good and I love that it gives you a good amount of protein. It wasn’t too strong of a cinnamon flavor and it wasn’t too sweet. The only complaint that I had was that it tasted a little too much like protein. The protein taste was a little too strong but other than that the cereal was really tasty!

Cinnamon tastes artificial

16 days ago
The flavor is more of an artificial cinnamon flavor . I did like the scent of the cereal when opening the box up. Overall not a product that I would purchase.

Healthy nutrition and tasty

a month ago
I love this special k protein cereal from Kelloggs brand because it's always consistent. Very decent size box and decent portions at affordable prices. I can keep it fresh by storing the cereal in a cereal container. Usually with this box and the size of our household we finish it within 3 days. My kids love the cinnamon tastes. It's lightly sweetened and crunchy in every bite.

Delicious and crunchy

a month ago
Really delicious cereal that doesn’t taste like it has extra protein. It has a satisfying crunch and doesn’t get soggy too quickly. Would definitely buy, and try other flavors! Prepared with 2 percent milk. There’s mo particular scent.

Healthy and not too sweet

a month ago
The cereal flakes were nice and crunchy, but I didn’t like the taste. It says that they’re sweetened, but they didn’t taste sweet at all. Must be minimally sweetened. I usually like cereal dry so that it’s easier to carry as a snack. I think I may have liked these more if they were sweeter but maybe they’re just healthier.

Quick, Easy, Delicious Protein

a month ago
This is a great breakfast option! It’s quick and easy, but also helps me to get my protein. I like the cinnamon flavor, especially in the milk afterwards! It doesn’t taste like it’s trying too hard with the protein like some protein foods do and I’d recommend it.

High protein cinnamon Chex

a month ago
Easy to eat cereal! Not strong and overpowering flavor, portion size is great. A healthier version of cinnamon Chex, and made me ready for my workout after eating. Love it with fruit!
