What are the health benefits of vitamin K for women?

Vitamin K helps strengthen the bones and is thought to lower the risk of fractures. Research shows that people with osteoporosis have low blood levels of vitamin K. In a Dutch study, 70 postmenopausal women who were given 1 milligram (1,000 micrograms) of vitamin K daily for three months experienced significant decreases in urinary calcium loss.

Japanese researchers studying the effects of vitamin K in protecting bones found that this vitamin may also help protect against liver cancer. Female subjects with viral liver cirrhosis who increased vitamin K intake were 90 percent less likely to develop liver cancer than those in a control group. Just 1 cup of spinach provides nearly 1,000 percent of a woman’s daily vitamin K needs. Top vitamin K sources include broccoli, arugula, collard greens, cabbage, grapes, blueberries and leafy green vegetables like kale, spinach and romaine lettuce.
