The journal Diabetes Care has reported that thefirst study to investigate the relationship between type 2 diabetes and Vitamin K intake has been conducted by the University Medical Center Utrecht in the Netherlands. In their study, 38,094 Dutch participants were analyzed for intake of vitamin K1 (phylloquinones) and vitamin K2 (menaquinones). Participants that averaged 200mcg/d of vitamin K1 and 31 mcg of vitamin K2 were followed for 10.3 years. A 19 percent drop in risk of developing type 2 diabetes was noted in men and women who had the highest consumption of K1 (phylloquiniones). Reduction was noted in all groups where vitamin K was increased.
The finding of this study show that both phlloquinones and menaquinone intake can be associated with reduced risk of type 2 diabetes.
Vitamin K can be found in spinach, kale, and olive oil or as a dietary supplement.
