Vitamin K levels may be too low in early menopause

As estrogen levels drop in early menopause, vitamin K function - which is essential to maintain normal clotting -- in bone is impaired before any actual bone loss occurs, new research shows.
"Our study suggests that the generally accepted level of vitamin K in healthy women is inadequate to maintain bone health just at the onset of menopause," lead author Dr. Jane L. Lukacs, from the University of Michigan at Ann Arbor, said in a statement.
The findings, which appear in the current issue of Menopause, indicate that the percentage of osteocalcin is a marker for the bone condition of health women in early postmenopause.
