Abstract

BACKGROUND: Multiple cross sectional and longitudinal studies reported the benefits of vitamin K intake for management of cardiometabolic risk factors so as to minimize the risk of cardiovascular diseases. OBJECTIVE: In present systematic review and meta-analysis, we aimed to evaluate the effect of vitamin K supplementation on cardiometabolic risk factors. METHODOLOGY: A systematic literature search of PubMed, Cochrane central, Clinicaltrials.gov, Google Scholar, Web of Science, EBSCO and Scopus databases was done from inception to November, 2017. A total of 13 trials were selected for inclusion into the present systematic review to evaluate the effect of vitamin K supplementation on cardiometabolic risk factors in healthy or in population at high risk of cardiovascular diseases. RESULTS: Significant beneficial effects of vitamin K supplementation were found only in case of Creactive protein (p = 0.01) and insulin sensitivity index (p <0.001), while no significant effects of vitamin K supplementation were found in case of total cholesterol (p=0.857), low density lipoprotein - cholesterol (p=0.964), high density lipoprotein - cholesterol (p=0.998), interleukin - 6 (p=0.766), systolic blood pressure (p=0.660), diastolic blood pressure (p=0.818), fasting plasma glucose (p=0.362), fasting plasma insulin (p=0.928) and homeostasis model assessment for insulin resistance (p=0.672). CONCLUSION: Presently available evidence are insufficient to ascertain the beneficial effects of vitamin K supplementation for the management of cardiometabolic risk factors. In order to explore the true potential of vitamin K supplementation for management of cardiometabolic diseases, large randomized placebo controlled trials are required in population with disturbed cardiometabolic profile. Present systematic review and meta-analysis is registered with PROSPERO (Registration number: CRD42018084608).
