Original Lucky Charms are deliciously gluten-free.
Although oats and marshmallows are naturally gluten-free, sometimes extra grains of barley, wheat and rye, which can contain gluten, get mixed in during the harvesting process and the transport from the farm.
The magical difference is in their sifting process.
First, they check the oats after sifting to make sure they contain less than 20 parts per million of gluten.
Then, they check it again after the oats are milled into flour. They always ship the flour to their plants in their fleet of dedicated gluten-free trucks and rail cars.
Lastly, after the flour is baked into Original Lucky Charms cereal, they check one last time to ensure Original Lucky Charms are gluten-free.
