NAD+

Energize & Elevate

Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme found in virtually every living cell. It participates in hundreds of metabolic reactions and is fundamental to cellular energy production, mitochondrial activity, and normal cellular maintenance.

NAD+ and NADH

NAD+ exists in two primary forms: NAD+ (the oxidized form) and NADH (the reduced form). These forms work together in cellular metabolism by accepting and donating electrons. During cellular metabolism, NAD+ accepts electrons and becomes NADH. NADH then delivers those electrons to the mitochondrial electron transport chain. The resulting proton gradient helps drive ATP synthase, which produces ATP, the primary energy currency used by cells.

Additional Biological Roles

DNA maintenance: NAD+ is consumed by enzymes such as PARPs, which participate in DNA-damage responses.
Sirtuin activity: NAD+-dependent enzymes involved in metabolic regulation and cellular stress responses.
Mitochondrial function: Support of metabolic pathways involved in cellular energy production.
Cellular signaling: Participation in pathways that regulate normal cellular activity.

The Healthy-Aging Connection

NAD+ is naturally produced and recycled by the human body. Research has identified age-associated changes in NAD+ metabolism in several tissues. Potential reasons include increased consumption by NAD+-dependent enzymes, changes in the efficiency of NAD+ synthesis and recycling, inflammation and cellular stress, and changes in mitochondrial function and tissue composition. However, NAD+ does not necessarily decline uniformly throughout every tissue in every person. Human studies remain limited, and a 2025 review in Nature Metabolism emphasized that evidence for a consistent age-related decline in human NAD+ levels is still incomplete.

Why supporting NAD+ availability is scientifically interesting

Maintaining cellular energy metabolism
Supporting mitochondrial function
Supporting normal DNA-maintenance pathways
Maintaining NAD+-dependent cellular signaling
Understanding metabolic changes associated with aging

Evidence Context

Human research involving NAD+ precursors such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) has demonstrated increases in certain NAD-related biomarkers. However, improvements in longevity, cognition, physical performance, or overall health have not been consistently established.
