Low levels of circulating Vitamin K linked to mobility limitation in older adults Study

Scientists have found that a low level of circulating vitamin K is associated with restricted mobility and disability in older adults. According to the study, this newly identified factor can be considered to maintain mobility and independence in old people. The study was published in the 'Journal of Gerontology: Medical Sciences'. Low vitamin K status has been associated with the onset of chronic diseases that lead to disability, but the work to understand this connection is in its infancy. Using participant data from the Health, Aging, and Body Composition Study (Health ABC), the study found that older adults with low levels of circulating vitamin K were more likely to develop mobility limitation and disability. Older adults with low circulating vitamin K levels were nearly 1.5 times more likely to develop mobility limitation and nearly twice as likely to develop mobility disability compared to those with sufficient levels. This was true for both men and women. The study used data from 635 men and 688 women of ages 70-79 years, who participated in Health ABC. Circulating vitamin K levels reflect the amount of vitamin K in the diet. The best food sources of vitamin K include leafy greens such as spinach, kale and broccoli and some dairy products.
