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

That said, not all studies report similar results.

For instance, one study compared nutrient levels in sprouts, microgreens, and fully grown amaranth crops. It noted that the fully grown crops often contained as much, if not more, nutrients than the microgreens

Therefore, although microgreens generally appear to contain higher nutrient levels than more mature plants, this may vary based on the species at hand.
