Low vitamin K may reduce mobility in older adults
Older adults with insufficient vitamin K are likely to be at higher risk for mobility disability, according to new research.
Dietary sources of vitamin K include kale, spinach, broccoli, and other leafy greens. Some dairy foods also contain vitamin K.
The investigators who carried out the study say that their findings "suggest vitamin K may be involved in the disablement process in older age."
They describe their work in a paper that features in a recent issue of The Journals of Gerontology: Series A.
Previous studies have established links between vitamin K and long-term conditions that can raise the risk of mobility disability. These conditions include cardiovascular disease and osteoarthritis.
