Excellent question, Wheatgrass is gluten-free, even though it's a wheat product. It is harvested before the gluten-containing wheat seeds sprout. Pure oats are also gluten-free and safe for most people with gluten intolerance. However, oats are often contaminated with gluten because they may be processed in the same facilities as gluten-containing grains like wheat, rye, and barley. We are unsure to the exact processing facilities of our oats; therefore, we cannot confirm their decontamination.
