Description What is NAD ? NAD (Nicotinamide Adenine Dinucleotide) is not a peptide — it’s a coenzyme that is absolutely essential for life. Found in every cell in the body, NAD is involved in hundreds of biological processes including energy production, DNA repair, gene expression, and cellular communication. What has made NAD one of the biggest stories in longevity research is the discovery that its levels decline dramatically with age — by up to 50% between the ages of 40 and 60. This decline has been linked to many of the hallmarks of aging, which has fuelled intense scientific interest in whether restoring NAD levels can reverse age-related decline. What Researchers Are Exploring Anti-Aging & Longevity NAD is considered one of the most important molecules in aging research. It is required for the activity of sirtuins — a family of enzymes often called “longevity genes” — which play key roles in DNA repair, inflammation control, and cellular stress response. Research suggests declining NAD may be a root cause of many age-related changes. Cellular Energy Production NAD is essential for converting food into cellular energy through the mitochondria. Research has explored how declining NAD levels contribute to reduced energy, fatigue, and metabolic slowdown associated with aging. DNA Repair NAD is consumed by PARP enzymes during the DNA repair process. As NAD declines, the body’s ability to repair DNA damage also declines — a process linked to aging and cellular dysfunction. Research has explored whether boosting NAD can support the body’s DNA repair capacity. Brain Health & Neuroprotection The brain is one of the most energy-demanding organs, making it particularly sensitive to NAD decline. Research has explored NAD supplementation for neuroprotection, cognitive function, and neurodegenerative conditions. Metabolic Health Studies have examined NAD ’s role in metabolic function, insulin sensitivity, and fat metabolism — with research suggesting that restoring NAD may improve metabolic health markers that deteriorate with age. Worth Noting NAD is arguably the single most researched molecule in the longevity and anti-aging field. The depth of published research linking NAD decline to aging is extensive, and it sits at the intersection of energy production, DNA repair, and sirtuin activation — three of the most active areas in longevity science.
