NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme essential for cellular energy production, DNA repair, metabolic regulation, and stress-response pathways. Levels of NAD+ naturally decline with age and stress, making it a popular target in wellness and longevity supplementation trends aiming to support energy, metabolism, and cellular resilience.Â
NAD+ is not a peptide in the strict biochemical sense — it’s a dinucleotide coenzyme vital for:
- Cellular energy production (ATP generation)
- DNA repair and genomic stability
- Metabolic regulation and insulin sensitivity
- Activation of longevity pathways (e.g., sirtuins)
- Immune function and stress responseÂ
