Even though it is sprouted from the wheatberry and its origin is wheat, the young blade of grass is glutenfree.
The seed kernel of the grass is what contains the gluten and is not pressed when juicing. Wheatgrass is gluten-free and therefore not likely to cause an adverse reaction.
Wheatgrass is generally considered safe for those with celiac disease or have a sensitivity to gluten. However, it’s always best to consult your doctor if unsure of anything new you add to your diet.
