Can Vitamin K2 Protect Your Heart? A Large Study Suggests Yes
Dr. Kumar’s Take:
This large Dutch study found that higher dietary intake of vitamin K2—not K1—was associated with a lower risk of coronary heart disease in postmenopausal women. The benefit was strongest for the longer-chain forms of vitamin K2 (MK-7, MK-8, and MK-9), which are mainly found in fermented foods and certain cheeses. If you’re focused on heart health, incorporating K2-rich foods or considering supplementation may be worth discussing with your doctor.
