New Study Supports Vitamin K For Your Bones

Though it gets a lot less attention than calcium or vitamin D, without vitamin K,

your bones would be like chalk. This new study helps explain why.

Your bones need calcium, but they also need a hormone called osteocalcin.

Osteocalcin helps attract and bind calcium to your bones. And osteocalcin is

produced by vitamin K.

This new systematic review and meta-analysis of the role of vitamin K included 9

controlled studies of 2,570 postmenopausal women with osteoporosis. The form

of vitamin K used was K2, a form of vitamin K that is produced by bacteria in the

gut.

The meta-analysis showed that vitamin K significantly increased osteocalcin

compared to a placebo, indicating that vitamin K can promote bone formation.

Vitamin K also significantly increased bone-specific alkaline phosphatase, a key

marker of bone formation.

This study supports the role of vitamin K in improving bone formation in

postmenopausal women with osteoporosis.
