Vitamin
K and Bone Formation
Article Summary:
This trial was conducted to determine the relationship between the
dietary intake of vitamin K2 and bone health in premenopausal women.
Fermented soybeans were used in the study due to the fact that they
contain high amounts of vitamin K2. Four groups were randomly formed
out of 73 healthy premenopausal women: group 1 receiving no intake,
group 2 receiving intake once per month, group 3 receiving intake
once per week, and group 4 receiving intake three times per week.
This was carried out for 1 year, during which the women all took
the fermented soybeans at lunchtime. Stiffness index by quantitative
ultrasound and bone turnover markers was measured before the study,
at the 6-month mark, and after the 1-year period. Through a number
of tests, logistic regression analysis showed that group 4 had a
reduced risk of reduction of boen formation markers when compared
to group 1. This study concludes that vitamin K2 is beneficial and
may contribute to the promotion of bone formation.
