Vitamin K May Help Build Strong Bones
May 17, 2003
There is emerging evidence that vitamin K may play a protective role in fighting age-related bone loss that is mediated through the vitamin K-dependent gamma-carboxylation of certain proteins in bone, including osteocalcin.
The primary dietary form of vitamin K is phylloquinone vitamin K1, which is concentrated in green vegetables and certain plant oils.
According to one study, women with low dietary intakes of vitamin K were more likely to have decreased bone density. These results are similar to those of other studies that found an increased risk of hip fracture among persons with low dietary levels of vitamin K.
This emerging evidence provides further support to the hypothesis that dietary vitamin K may improve the strength of your bones if added to your diet.
Interestingly though, dietary vitamin K intake was not associated with bone density improvement in men, which means that there may be a sex-specific effect of vitamin K on bone.
