Yes, it is. This is why it's a great alternative to the majority of gluten-free recipes out there that use almond flour. If you have a nut allergy (like I do) then make sure to read the package label first - check for any cross-contamination information. Some brands might package the coconut flour in the same facility that also packages nut flours. There are many that don't do this and are safe - you'll just have to read labels in your local stores in order to find one.
