Wheatgrass is the young, leafy shoot of the common wheat plant (*Triticum aestivum*), harvested before the grain head forms. Do not confuse it with couch grass (*Elymus repens*). You can find it as fresh juice or in powdered supplements.
People reach for wheatgrass mainly for its dense mix of vitamins, minerals, and chlorophyll. They use it to help support immune function, lift energy levels, or add to a mild cleansing routine.
Take wheatgrass in the morning on an empty stomach. A typical fresh shot is 1 to 2 ounces. Mix the powdered form with water or juice. The grassy taste is strong, so many people chase it with fruit juice.
Cautions: Check with a doctor before taking wheatgrass if you are pregnant, nursing, or need a strict gluten-free diet. The grass itself is usually gluten-free, but cross-contamination can happen. Begin with a small dose to see how your body reacts. Nausea or stomach upset are possible.
