What is NAD?
Nicotinamide adenine dinucleotide (NAD) is a necessary molecule for maintaining life and is found in every cell. NAD is involved in redox reactions and comes in two forms: NAD+ and NADH. Insufficient NAD is involved in five out of the nine hallmarks of aging and can increase the risks of age-related diseases such as cancer, stroke, heart disease, diabetes, and neurodegenerative diseases.
NAD is necessary for major energy pathways such as glycolysis, the Krebs cycle, and oxidative phosphorylation. All of these pathways produce the body's energy currency: ATP. When NAD is not available, cells can't produce enough ATP to sustain important biological processes which leads to suboptimal health.
Sirtuins: aging regulators
Sirtuins are enzymes that require NAD+ to function and are involved in five hallmarks of aging. When there are healthy amounts of sirtuins and NAD+ cofactors, they inhibit the hallmarks: epigenetic alterations, mitochondrial dysfunction, deregegulated nutrient sensing, genomic instability, and cellular senescence.
The PARP enzymes use NAD to repair DNA to prevent genomic instability, a hallmark of aging.
The sirtuin enzymes also help prevent genomic instability by helping FOXO transcription factors to bind to DNA and express antioxidant enzymes to protect cells from oxidative stress.
NAD deficiency accelerates the hallmarks of aging
When the body does not have enough NAD, all of the above roles are harmed. Without enough NAD, genomic instability, epigenetic alterations, deregulated nutrient sensing, and poor energy metabolism hurt wellness and promote aging. NAD declines with age because it is consumed by enzymes, mainly CD38.
What are the risk factors for NAD deficiency?
NAD declines with age and contributes to disease
Obesity is also a risk factor for NAD depletion, possibly because it contributes to chronic inflammation, which causes DNA damage, requires NAD+-consuming PARP hyperactivation.
NAD deficiency is a common central pathological factor of a number of diseases and aging: cerebral ischemia, myocardial ischemia, diabetes, cancer, metabolic, neurodegenerative diseases, and other age-associated pathologies.
How can you optimize your NAD levels?
NAD precursor supplements such as NR and NMN have been shown to raise NAD levels in humans.
Diet and exercise
Obesity is associated with reduced expression of NAD and sirtuins, whereas weight loss increases NAD and sirtuin expression.
Exercise has been shown to increase activity of an NAD-synthesizing enzyme called NAMPT.
