Wheatgrass is completely gluten free if it was correctly harvested and only the grass is eaten. However, people with gluten sensitivity or celiac disease have to be careful not to eat any of the seeds that are produced by the grass if it's not harvested at the right time.

If a gluten-sensitive person is unsure if wheatgrass is completely gluten free, there are other green vegetables that provide roughly the same benefits, such as spinach.Learn more about Nutritional Content
