About





            

                
NMN is a direct precursor to NAD+, a critical coenzyme for mitochondrial energy metabolism and sirtuin-mediated cellular repair. NAD+ levels decline approximately 50% between ages 40-60, correlating with cardiovascular aging. A 2024 RCT showed NMN at 250 mg/day improved arterial stiffness and reduced aortic pulse wave velocity in middle-aged adults.

            

        

        

        
        
        

            

  
How It Works





            

                
Direct precursor to NAD+ (nicotinamide adenine dinucleotide), a critical coenzyme for mitochondrial energy metabolism, sirtuin-mediated DNA repair, and PARP-mediated stress response; supports endothelial function by restoring SIRT1 activity in vascular smooth muscle; activates AMPK improving metabolic health markers associated with cardiovascular risk.
