Can vitamin K help protect my bones?

David Slovik, MD

Vitamin K helps produce osteocalcin, a protein that is instrumental in bone formation. It also blocks substances that break down bone and helps regulate calcium excretion from the body in urine.
A study published in the journal Maturitas concluded that therapy with vitamins D and K might increase bone mass in postmenopausal women. Researchers have also found that getting ample vitamin K protects against hip fracture. According to the Nurses' Health Study, women who got at least 100 micrograms (mcg) of vitamin K a day were 30% less likely to break a hip than women who got less than that amount. Similarly, the Framingham Heart Study found that participants who got the most vitamin K were less likely to break a hip than those who got the least.
