Wheat leaves, or grass, do not contain gluten. Gluten is found in the berry (the grain).
All the ingredients in our Perfect Greens as well as the finished product are tested for gluten. All batches need to contain less than 20 parts per million of gluten to meet the Health Canada requirement to be noted as gluten free.
The facility where the product is manufactured does not work with gluten, but it is important to note that because of the agricultural nature of the ingredients, this product is at higher risk for gluten contamination - the main concerns here would be wheat grass, barley grass, and oat grass at the ingredient supplier level (if the delivery truck is also used to carry barley grain, for example). So even though we do test and make sure the product contains less than 20 parts per million of gluten, it most likely does contain very tiny amounts of gluten. Meaning that If you have an allergy to gluten, we would err on the side of caution and recommend refraining from taking our Perfect Greens.
