Vitamin K2 Extends Lifespan by Alleviating Mitochondrial Stress via the JNK‐1/SIR‐2.1/DAF‐16 Signaling Axis in Caenorhabditis elegans
Vitamin K2 at optimal concentrations (5 μM) extends lifespan in C. elegans by activating a signaling pathway that protects mitochondria from oxidative stress, maintains ATP production, and enhances cellular stress resistance. This mechanism operates through preservation of mitochondrial function and reduction of reactive oxygen species accumulation.
