Shea MK, Kritchevsky SB, Loeser RF, Booth SL · The Journals of Gerontology. Series A

Extends the vitamin K story from the joint to what the joint is for: low vitamin K status was associated with more mobility limitation and disability in older adults over follow-up.

Population

Older adults in the Health, Aging and Body Composition study

Intervention

Higher circulating vitamin K status

Comparator

Lower status

Limitations

Mobility limitation has many causes; this is an association in an ageing cohort, without a joint-specific endpoint.
