NAD+ plays an important role in antioxidants

 

NAD+ is an antioxidant substance and an indispensable nutrient element in human cells. NAD+ participates in many redox processes in cells, which is beneficial to enhancing the antioxidant capacity of the skin and enhancing immunity. It is also beneficial to scavenging harmful free radicals, repairing the damage caused by harmful free radicals to the skin, delaying aging, and reducing melanin synthesis, so that Skin is whitened and shiny.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme widely present in living organisms and participates in many biochemical reactions. Together with ATP (adenylate), it serves as a key substance in energy metabolism.

From an antioxidant perspective, NAD+ has the following important functions:

1. Scavenge free radicals

Through its special chemical structure, NAD+ can effectively scavenge free radicals in cells and reduce their damage to cell structures. The reaction process between NAD+ and free radicals can form more stable substances, thus avoiding further damage to cells.

NAD+ is involved in the intracellular respiration process. In this process, NAD+ reacts with oxygen to generate more stable NADH, which is an important energy carrier. This process will generate some free radicals, but NAD+ can effectively remove these free radicals through its own structural characteristics, thereby avoiding oxidative stress.

2. Protect DNA from oxidative damage

DNA is the cell's genetic material and is vital to the cell's life.

NAD+ also plays a key role in the DNA repair process. When DNA is damaged, cells initiate repair mechanisms. In this process, NAD+ participates in the DNA repair process as a coenzyme, protecting DNA from free radical damage.

3. Delay cell aging

Cellular senescence is one of the main characteristics of aging, and the level of NAD+ gradually decreases during the aging process. Research has found that NAD+ supplementation can activate anti-aging genes such as SIRT1, regulate cell metabolism and protect cells from oxidative stress such as lipid peroxidation, DNA damage and inflammation, thereby delaying the cellular aging process.
