Excellent source of vitamin K

Both raw and cooked mustard greens are high in vitamin K, supplying 120 percent and 690 percent of the daily value (DV) per cup (56 grams and 140 grams, respectively). Vitamin K is widely known for its critical function in blood clotting. It's also been linked to better heart and bone health.

In fact, low vitamin K levels have been linked to an increased risk of heart disease and osteoporosis, a condition characterized by decreased bone strength and an increased risk of fractures. Recent research has also revealed a connection between vitamin K insufficiency and brain function. Inadequate vitamin K levels may be linked to an increased risk of cognitive impairment, dementia, and Alzheimer's disease.
