An Introduction to Nicotinamide Adenine Dinucleotide: What Is It and How Does It Work?

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in all living cells. It is a dinucleotide, composed of two nucleotides joined by a bridging phosphate group. One nucleotide contains an adenine base and the other contains a nicotinamide base.

So far, there is little proven evidence that NAD+ supplements health benefits, though there are ample anecdotes supporting these abilities. More research is needed to determine whether NAD+ supplements are safe and effective. Consult resources like to learn more about nicotinamide adenine dinucleotide and its potential benefits.

How Does NAD+ Work?

NAD+ is involved in a number of important cellular processes. It is needed for the:

  • production of energy

  • regulation of gene expression

  • repair of DNA damage

  • maintenance of muscle mass

Production of Energy

The energy currency of the cell is Adenosine triphosphate (ATP). ATP is produced by the conversion of food molecules into energy. This process is called metabolism. The energy needed for metabolism is supplied by the breakdown of adenosine diphosphate (ADP) into ATP. This process is called phosphorylation.

NAD+ is a key player in the phosphorylation reaction. It is a coenzyme that is needed for the conversion of ADP into ATP. NAD+ is also needed for the conversion of glucose into energy.NAD+ is produced by the body from the amino acid tryptophan. Tryptophan is converted into niacin, which is then converted into NAD+.

NAD+ is especially important for the production of energy from food. It is needed to turn food into ATP. Without NAD+, the body would not be able to produce energy from food.

NAD+ is also important for the health of the cells. It is needed for the maintenance of the cell membrane and for the production of DNA and RNA.

Regulation of Gene Expression

NAD+ also helps to regulate gene expression. It can turn on or off the expression of certain genes. This is important for the cell because it allows it to respond to changes in its environment. For example, if the cell needs to produce more energy, NAD+ can help to turn on the genes that are responsible for producing energy. If the cell needs to respond to a foreign invader, NAD+ can help to turn on the genes that are responsible for fighting the invader.

One of the most important roles of NAD+ is in DNA repair. When DNA is damaged, NAD+ helps to fix the damage. This is important because DNA damage can lead to cancer and other diseases.

NAD+ is also involved in gene expression. Gene expression is the process by which genes are turned on or off. It is regulated by a number of factors, including NAD+ levels. When NAD+ levels are low, gene expression is inhibited. This can lead to a number of problems, including cancer.

Repair DNA Damage

NAD+ levels decline as we age. This is one of the reasons why older people are more susceptible to disease. NAD+ supplements can help to increase NAD+ levels and improve DNA repair and gene expression. This can help to reduce the risk of disease and improve overall health.

Maintenance of Muscle Mass

NAD+ also helps to maintain muscle mass. Muscles need NAD+ to function properly. When NAD+ levels decline, muscles can start to waste away.

One way to help maintain muscle mass is to supplement with NAD+ precursors such as nicotinamide riboside. NAD+ precursors can help to increase NAD+ levels in the body, which in turn can help to preserve muscle mass.
