NAD+ supplement is a type of dietary supplement that contains either NAD+ (nicotinamide adenine dinucleotide) or its precursors, such as NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside). These molecules can enter the cells and be converted into NAD+, which is a vital coenzyme that participates in many biochemical reactions in the body. NAD+ is essential for the function of enzymes called sirtuins, which regulate gene expression, inflammation, and cellular stress response. NAD+ also plays a key role in the production of ATP, which is the main source of energy for the cells. However, NAD+ levels decline with age, which may impair the cellular functions and contribute to aging and age-related diseases. Taking NAD+ supplement may help restore the NAD+ levels and support the cellular functions. Some of the potential benefits of NAD+ supplement include:
Anti-aging: NAD+ supplement may delay the aging process by activating sirtuins, which can protect the DNA from damage, enhance the mitochondrial function, and extend the lifespan of cells .
Cognitive function: NAD+ supplement may improve the brain function by increasing the blood flow to the brain, enhancing the neuronal activity, and protecting the neurons from oxidative stress and inflammation .
Metabolic health: NAD+ supplement may improve the metabolic health by regulating the glucose and lipid metabolism, increasing the insulin sensitivity, and preventing the accumulation of fat in the liver .
Immune function: NAD+ supplement may boost the immune function by modulating the immune cells, enhancing the anti-viral response, and reducing the chronic inflammation .
