Finding New Health Benefits for Vitamin K
Study links vitamin K levels to longevity.
Vitamin K, once thought important primarily for blood clotting, may have a much wider array of health benefits. One recent Spanish study reported that people with the highest dietary intake of vitamin K were at significantly lower risk of mortality from cardiovascular disease, cancer and all causes. And if you’re not already consuming plenty of vitamin K—found in dark leafy greens, broccoli, Brussels sprouts and other vegetables (see box)—it’s not too late to start: The study also found that people who increased their vitamin K intake were at lower mortality risk.
