“There is a recommended daily amount for vitamin K that varies with age.
“Consuming adequate amounts of vegetables and fruits is satisfactory to maintain normal vitamin K levels.

The researchers said their findings could have strong implications for patients with dementia and suggest it may be useful to monitor levels in at-risk individuals.
