Hi! I haven’t seen any Sprouts brand corn flakes at my local stores or online, but many of the brands I mentioned are carried at Sprouts! (Nature’s Path & Barbara’s, for instance).

I don’t live by a GreenWise, so I can’t check in person, but from what I can see online, the only ingredients in the GreenWise Organic Corn Flakes cereal are organic corn, organic cane sugar, and sea salt. I don’t see a gluten-free certification on the box specifically, but I also don’t see a “may contain gluten” or “may contain wheat” statement on their packaging. If you have Celiac, it’s probably worth using a certified gluten-free brand to avoid getting sick. If you’re gluten intolerant, you’ll have to decide what your level of comfort is without the certification. Wishing you luck!
