The young grass of the wheat plant, juiced into a vivid green shot. A health-store icon with a big reputation — and an honest, more modest evidence base than the hype suggests.
Cheap to grow at home from bulk wheat berries — if you want the green shot, grow it for cents rather than paying juice-bar prices, and spend the savings on a wider range of greens.
Honest framing: wheatgrass is a nutritious green juice — real chlorophyll, vitamins A and C, iron, and antioxidants — and small studies suggest a modest benefit in ulcerative colitis and as a supportive food in some anemias. But it is not a miracle, not a cure, and not nutritionally superior to simply eating a variety of leafy greens, which cost far less. The claims that it 'detoxes the blood' or carries unique cleansing power are marketing, not science. A fine green shot; a poor reason to spend health-store money.
Grow wheat berries on a soil tray, harvest the grass at 7-10 days (the jointing stage), and juice in a masticating or wheatgrass juicer — a blender won't extract it well. Drink fresh, 1-2 oz, on a relatively empty stomach. The taste is intensely grassy and sweet; many chase it with water or citrus.
