What Is Nicotinamide Adenine Dinucleotide (NAD+)?

Nicotinamide Adenine Dinucleotide or NAD+ is a coenzyme found central to almost all types of anabolic and catabolic biochemical reactions. It is present in all living cells and was first discovered by Sir Arthur Harden in a boiled yeast extract. The structure of NAD+, as indicated by its name, consists of two covalently bonded mononucleotides, one of which consists of Adenine nucleobase and the other consists of Nicotinamide.

How Does NAD+ (Nicotinamide Adenine Dinucleotide) Work?

It is a well-known fact of science and chemistry, mainly that electrons are a source of energy. Their transport, loss, or gain is a source of energy. This energy helps drive all processes of life.

Nicotinamide Adenine Dinucleotide is the main shuttle bus that brings about the transfer of electrons between molecules and cells inside living organisms. It participates in all the vital energy-producing chemical reactions in the body. Without sufficient levels of NAD+, the body will go into an energy deficit state and will not be able to carry out the life processes.

In addition to energy production, Nicotinamide Adenine Dinucleotide regulates the circadian and sleep/wake cycle.

Changes In Nicotinamide Adenine Dinucleotide Concentrations With Age

The aging process results from a gradual decline in Nicotinamide Adenine Dinucleotide levels, indicating that low levels of NAD+ may contribute to some age-related diseases and an overall decline in the body.

Research suggests that DNA damage, one of the hallmarks of aging, activates a family of enzymes called PARPs. The PARPs repair the damaged DNA by using NAD+. With more damaged DNA during aging, the PARPs will consume more Nicotinamide Adenine Dinucleotide resulting in a decline in its concentration.
Research also suggests that immune system activity increases with aging via the activation of different enzymes. Since these enzymes use Nicotinamide Adenine Dinucleotide in some ways, immune system overactivity can reduce NAD+ levels in the body.

Sirtuins are another class of proteins associated with healthy aging by bringing about the genetic repair of chromosomes. These sirtuins also use NAD+ and hence, reduce their concentrations with aging.

Uses Of Nicotinamide Adenine Dinucleotide According To Research

Extensive investigations have been done on the potential uses and benefits of NAD+. According to these studies, Nicotinamide Adenine Dinucleotide can be helpful in the following conditions:

• Improvement of cardiovascular functions
• Protection of the nervous system
• Improvement of muscle activity and health
• Anti-aging properties
• Protection against metabolic disorders

There is now enough proof to demonstrate that the decrease in the levels of Nicotinamide Adenine Dinucleotide in the body is associated with various disorders, mainly being a hallmark of aging. Since the boosting of NAD+ levels in the body has been linked with protection against various metabolic and neurodegenerative disorders, researchers can deduce that exogenous administration of it can play an anti-aging role.

Its anti-aging effect is so potent that laboratory animals’ replenished Nicotinamide Adenine Dinucleotide levels have improved their lifespan.

NAD+ and Muscle Development
Nicotinamide Adenine Dinucleotide is a critical player in regulating muscle activity and its growth and sustainability. Several studies on muscle tissue from mice have indicated that high levels of NAD+ in the muscle tissue are associated with improved muscle health and development. On the contrary, decreasing NAD+ has harmful effects on skeletal muscle development, regeneration, and aging.

Nicotinamide Adenine Dinucleotide improves muscle health and activity by the upregulation of mitochondria in the muscle cells. Since mitochondria are the powerhouse driving all the energy-requiring processes in the muscle cells, improving its function improves muscle health.

NAD+ and Metabolism
The recent spike in the prevalence of metabolic disorders worldwide makes it a concerning issue for the medical community. Obesity alone, which has recently been declared an epidemic by the WHO, kills roughly 1.6 million people worldwide, and it is just one of the many metabolic disorders.
Aging and high-fat diet intake predispose individuals to various metabolic disorders. It is also closely associated with reduced Nicotinamide Adenine Dinucleotide levels. Studies have proven that NAD+ administration can change healthy weight and exercise capability. In some mice, Nicotinamide Adenine Dinucleotide administration has even improved insulin sensitivity and the prognosis of diabetes.

NAD+ and the Heart
The elastic degeneration of the walls of arteries is one of the most common pathologies associated with cardiac dysfunction.
Research on mice has proven that boosting NAD+ levels improve cardiac functioning. By maintaining the levels of NAD+ at the baseline, we can reduce the risk of heart enlargement and ischemic death and injury significantly.
To conclude, it has potent effects on all major body systems. Nicotinamide Adenine Dinucleotide could be the key to anti-aging and longevity that we have been looking for.
