To evaluate the effect of supplementation of vitamin K2 (menaquinone, MK-7)vs vitamin k1 on circulating levels of calcification regulators and to assess their safety in patients on regular dialysis patients.


Vascular calcification has emerged as an independent risk factor for cardiovascular morbidity and mortality, especially in chronic kidney disease .

It has a predictive value of poor prognoses and clinical outcomes in CKD patients such as overall mortality and even poor arteriovenous graft maturation .

Vitamin K is essential for the activation of matrix Gla protein (MGP), a powerful inhibitor of tissue calcification, functional vitamin K deficiency may contribute to high vascular calcification (VC) burden in haemodialysis patients; this is process in which mineral is pathologically deposited in blood vessels, mainly in large elastic and muscular arteries such as the aorta and the coronary, carotid, and peripheral arteries.

it is Prospective, Randomized,Placebo Controlled Study
