Highlights
β’ Studies showed vitamin K2 intake reduced 7% T2DM risk with each 10-ΞΌg increment.
β’Vitamin K2 has a more significant effect than vitamin K1 on T2DM.
β’Vitamin K2 increased insulin sensitivity via osteocalcin metabolism.
β’Vitamin K2 improved IR via anti-inflammatory property and lipid-lowering effects.
β’Vitamin K2 suppresses inflammation via inactivating NF-ΞΊB signalling pathway.
β’Vitamin K2 supplementation decreases fat accumulation and serum triglycerides.

Type 2 diabetes mellitus (T2DM) continue to be a major public health problem around the world that frequently presents with microvascular and macrovascular complications. Individuals with T2DM are not only suffering from significant emotional and physical misery, but also at increased risk of dying from severe complications. In recent years, evidence from prospective observational studies and clinical trials has shown T2DM risk reduction with vitamin K2 supplementation. We thus did an overview of currently available studies to assess the effect of vitamin K2 supplementation on insulin sensitivity, glycaemic control and reviewed the underlying mechanisms. We proposed that vitamin K2 improved insulin sensitivity through involvement of vitamin K-dependent-protein osteocalcin, anti-inflammatory properties, and lipid-lowering effects. Vitamin K2 had a better effect than vitamin K1 on T2DM. The interpretation of this review will increase comprehension of the development of a therapeutic strategy to prevent and treat T2DM.
