Effect of Vitamin K2 in the Treatment of Nocturnal Leg Cramps in Older Population

Vitamin K2 is a fat-soluble and one of the body's indispensable vitamins. It is mainly synthesized by gut bacteria in the body and plays a role in the mitochondrial electron transport chain. It boosts calcium metabolism, acts on osteoblasts, and promotes bone tissue calcification. It also inhibits osteoclasts from causing bone resorption, thus increasing bone density, and preventing osteoporosis. Furthermore, it regulates the use of calcium and promotes the inhibition of vascular calcification by matrix Gla protein (MGP) activity. Vitamin K2 supplementation at recommended dosage does not affect vitamin K-dependent coagulation factors' activity. It does not enhance the carboxylation of prothrombin in healthy individuals. Vitamin K2 administration does not alter the hemostatic balance in healthy populations without anticoagulation treatment. Thus, vitamin K2 is deemed to have a good safety profile.
