Technical Abstract: Average self-reported dietary intakes of vitamin K are below recommended intakes among adults in the U.S. and U.K.. Low dietary intakes of vitamin K are potentially a modifiable risk factor for osteoporosis. In humans, much of the supporting evidence of a role for dietary vitamin K in age-related bone loss is based on reported associations between dietary intakes or biological markers of vitamin K status and bone mineral density (BMD) or hip fracture risk. However, one criticism of these epidemiologic data is the potential confounding effect of overall poor nutrition. There is also some evidence that different forms of vitamin K may have variable influence on bone turnover. The proposed dietary role of vitamin K as a risk factor for osteoporosis would be strengthened if controlled changes in vitamin K intakes, obtained from the diet or supplements, were consistently shown to influence bone metabolism.
