Abstract
Objective: To systematically review research on the association between vitamin K and type 2 diabetes and diabetes-related biomarkers in humans, and evaluate the role of vitamin K in the prevention of type 2 diabetes. Methods: "Vitamin K", "type 2 diabetes" and related terms were searched in PubMed, EMBASE, China National Knowledge Infrastructure (CNKI) and Wanfang Med Online up to November 2018. Results: A total of 1 Chinese and 12 English articles were included. Among 6 observational studies, 5 of them showed that higher dietary vitamin K intake and plasma vitamin K level were associated with the decrease of the risk of type 2 diabetes. Among 6 clinical intervention studies, 5 of them indicated that the supplementation of vitamin K(1) or K2 could have positive influence on insulin metabolism. One Mendelian randomization study showed higher circulation vitamin K level might reduce the risk of type 2 diabetes. Conclusion: Vitamin K plays an important role in the prevention and control of type 2 diabetes, which may be related to the improvement of insulin metabolism and blood glucose level.
