The main function of NAD+  capsule(nicotinamide adenine dinucleotide) is to replenish the level of NAD+ in the body. NAD+ is essential in cell metabolism, especially in energy production and DNA repair.

Main functions:
Energy metabolism:
Participate in cellular respiration: NAD+ capsules helps convert nutrients into ATP in mitochondria to provide cellular energy.
Sugar, fat, protein metabolism: NAD+ is an important coenzyme in these metabolic processes.
DNA repair:
Activate PARP enzyme: NAD+ is a substrate of PARP enzyme and participates in DNA damage repair.
Maintain genome stability: By supporting DNA repair, NAD+ helps maintain genome integrity.
Anti-aging:
Activate sirtuins: NAD+ activates sirtuins proteins and participates in regulating cell aging and lifespan.
Reduce oxidative stress: NAD+ helps reduce damage to cells by free radicals.
Cell signaling:
Regulate calcium signaling: NAD+ affects intracellular calcium ion concentration and regulates a variety of cell functions.
Influence on gene expression: Through sirtuins, NAD+ participates in the regulation of gene expression.
