NAD Therapy


Nicotinamide Adenine Nucleotide

NAD was first described in 1906 by Harden and Young as a cell component that enhanced alcohol fermentation (Harden and Young, 1906). Then in 1936, Warburg showed that NAD is required for redox reactions (Warburg and Christian. 1936) and solidified the nomenclature: "NAD" refers to the chemical backbone irrespective of charge, "NAD+" and "NADH" refer to the oxidized and reduced forms respectively. In 1963, a breakthrough came with the discovery that NAD+ is a co-substrate for the addition of poly-ADP-ribose to proteins (Chambon et al.. 1963).

Nicotinamide adenine nucleotide (NAD+) has emerged as a key regulator of cellular processes that control the body's response to stress. NAD boosters, small molecules that raise NAD+ levels, are now considered to be highly promising for the treatment of multiple diseases and the potential extension of the human lifespan.

Nicotinamide adenine dinucleotide (NAD) is one of the most important and interesting molecules in the body. It is required for over 500 enzymatic reactions and plays key roles in the regulation of almost all major biological processes (Ansari and Raghava. 2010). Above all, it may allow us to lead healthier and longer lives.

By modulating NAD+ sensing enzymes, it controls hundreds of critical processes from energy metabolism to cell survival, rising and falling depending on food intake, exercise, and the time of day.

NAD+ levels steadily fall as we age, leading to a decline in the function of cells and organs. By raising NAD+, NAD+ boosters can have profound effects on the health and survival of mammals. Increases in NAD+ promote cognitive and sensory function, gluconeogenesis in the liver, lipogenesis in adipose tissue, insulin secretion in the pancreas, and insulin sensitivity in muscle. NAD+ also promotes endothelial cell proliferation and protects against cardio- and cerebrovascular disease. NAD regulates immune function and inflammation and, protects against acute injury in the kidney. NAD promotes and extends fertility in both males and females, ostensibly by activation of sirtuins.

The Potential Impact of NAD+ Boosters on Human Health Via NAD+ Signaling Pathways

A decline in NAD+ during aging is believed to be a major cause of disease and disability, such as hearing and vision loss, as well as cognitive and motor dysfunction, immune deficiencies, auto-imunity and dysregulation of the inflammatory response leading to arthritis, metabolic dysfunction and cardiovascular disease. In mouse models, NAD+ boosters prevent or treat a variety of different diseases, prompting a search for NAD+ boosters that are safe and effective as drugs to treat both rare and common diseases, and potentially aging itself.

Liver Function

Key enzymes in NAD+ signaling pathways are known to protect the liver from fat accumulation, fibrosis, and insulin resistance, which are related to the development of fatty liver diseases, such as NAFLD and NASH.

Kidney Function

Several lines of evidence indicate that reduced levels of NAD+ in aged kidneys and a corresponding decrease in sirtuin activity are largely responsible for reduced kidney function and resilience with age (Ugur et al., 2015).

Skeletal Muscle Function

Old mice have increased markers of muscle atrophy and inflammation, as well as impaired insulin signaling and insulin-stimulated glucose uptake compared to young wild-type mice. Treatment of old mice with NAD+ precursors, such as NR and NMN, dramatically improves muscle function
