Wheatgrass is a food derived from the cotyledons (seedlings) of the common wheat plant. It is often ground into a concentrated powder or juiced from its raw form to be used in various juices and health supplements.
Wheatgrass has been shown to work as an antioxidant, damage cancerous cells, promote wound healing, inhibit oxidative damage, and strengthen the immune system.
Given that wheatgrass does not contain wheat seeds, it therefore does not contain gluten, assuming the product is not contaminated.
