Vitamin K supplementation did not affect insulin sensitivity as measured by homeostasis model assessment of insulin resistance , fasting plasma glucose , fasting plasma insulin , C-reactive protein , adiponectin , leptin , and interleukin-6 levels .
Our analysis suggests no effect of vitamin K supplementation on insulin sensitivity
OBJECTIVE To perform a systematic review and meta- analysis of r and omized , placebo-controlled trials to assess the effect of vitamin K supplementation on insulin sensitivity .
Dietary Phylloquinone and Menaquinones Intakes and Risk of Type 2 Diabetes
OBJECTIVE To investigate whether dietary phylloquinone and menaquinones intakes are related to risk of type 2 diabetes .  RESEARCH DESIGN AND METHODS We used data from a prospect i ve cohort study in 38,094 Dutch men and women , aged 20–70 years .  Dietary phylloquinone and menaquinones intakes were assessed using a vali date d food frequency question naire . Diabetes case patients were ascertained mainly via self-report and verified against medical records . RESULTS During 10.3 years of follow-up , 918 incident cases of diabetes were documented . In a multivariate model adjusting for diabetes risk factors and dietary factors , phylloquinone intake tended to be associated ( P = 0.08 ) with a reduced risk of type 2 diabetes with a hazard ratio ( HR ) of 0.81 ( 95 % CI 0.66–0.99 ) for the highest versus the lowest quartile . For menaquinones intake , a linear , inverse association ( P = 0.038 ) with risk of type 2 diabetes was observed with an HR of 0.93 ( 0.87–1.00 ) for each 10-μg increment in the multivariate model . CONCLUSIONS This study shows that both phylloquinone and menaquinones intakes may be associated with a reduced risk of type 2 diabetes
