The Role of Vitamin K in Neurodegenerative Disorders: Mechanisms, Evidence, and Therapeutic Potential
Keywords:
N\AAbstract
Neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), and Multiple Sclerosis (MS), pose significant public health challenges worldwide. Emerging evidence suggests that Vitamin K, a fat-soluble vitamin traditionally known for its role in blood coagulation, also has neuroprotective properties. This review explores the role of Vitamin K in neurodegeneration, focusing on its antioxidant, anti-inflammatory, and neuroprotective functions. It also evaluates the clinical and experimental evidence that support the potential of Vitamin K as a therapeutic agent for neurodegenerative disorders. The paper highlights the need for further research to elucidate the precise mechanisms of Vitamin K in brain health and its translational application in neurodegenerative conditions
