A study at the prestigious Tufts University showed that older adults with lower levels of vitamin K were more likely to die early than those with higher levels.
The test analysed the vitamin K levels of over 4,000 adults between 54 and 76. Over the following 13 years after the start of the test, rates of heart attack and death were compared between a group with lower vitamin K levels and a group with higher levels.
There was no significant effect on the rates of heart attack, but the group with a lower vitamin K level had 19% more deaths than the group with the higher level.
Experts know that vitamin K is important for blood vessel health, so they were surprised there was no real benefit for heart disease. And they are not sure how vitamin K could reduce rates.
So more research is needed. But keeping your vitamin K level high is important.
