Microgreens are packed with nutrients.
While their nutrient contents vary slightly, most varieties tend to be rich in potassium, iron, zinc, magnesium and copper. Microgreens are also a great source of beneficial plant compounds like antioxidants. What’s more, their nutrient content is concentrated, which means that they often contain higher vitamin, mineral and antioxidant levels than the same quantity of mature greens. In fact, research comparing microgreens to more mature greens reports that nutrient levels in microgreens can be up to nine times higher than those found in mature greens. Research also shows that they contain a wider variety of polyphenols and other antioxidants than their mature counterparts.
One study measured vitamin and antioxidant concentrations in 25 commercially available microgreens. These levels were then compared to levels recorded in the USDA National Nutrient Database for mature leaves.
Although vitamin and antioxidant levels varied, levels measured in microgreens were up to 40 times higher than those recorded for more mature leaves.
