Nicotinamide adenine dinucleotide (abbreviated NAD)
also known as diphosphopyridine nucleotide (abbreviated DPN), or codehydrogenase I or Coenzyme I

Function of Nicotinamide Adenine Dinucleotide
Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells that is involved in the conversion of nutrients, affects the rate of metabolism, and decreases with aging. The main functions and effects of nicotinamide adenine dinucleotide are as follows:
1. Maintain normal skin function
Nicotinamide adenine dinucleotide can inhibit the formation and transport of melanin, so as to play a whitening effect.
2. Promote growth and development
Nicotinamide adenine dinucleotide can participate in the synthesis of coenzyme I and Coenzyme II in vivo, thus playing the above role.
3. Maintain normal vision
Nicotinamide adenine dinucleotide is converted into retinoic acid in the body and is used as a photoreceptor to help maintain normal vision.
4. Enhance body immunity
Nicotinamide adenine dinucleotide can regulate the function of immune cells, improve the body's resistance to disease, and achieve the purpose of enhancing the body's immunity.
5. Improve energy metabolism
Nicotinamide adenine dinucleotide can promote lipolysis, increase body heat production, and help to improve the abnormal situation of energy metabolism.
6. Participate in multiple biochemical reactions
As an important coenzyme, nicotinamide adenine dinucleotide is involved in many biochemical reactions and plays an important role in body metabolism.
7. Anti-aging effect
Although studies have shown that absorption of NAD+ may stimulate tumor cell growtit is believed that its anti-aging efficacy may be established in the case of promoting tumor development, NAD+ plays a key role in cell metabolism, inflammation, multiple diseases, healthy aging, and supporting cellular immune defense
