🐾 Anti-aging supplement Nicotinamide Mononucleotide (NMN)
The direct precursor of NAD⁺ - Nicotinamide Mononucleotide (NMN)
Nicotinamide Mononucleotide (NMN) is a naturally occurring nucleotide and the direct precursor of NAD⁺ (Nicotinamide Adenine Dinucleotide) – one of the most critical coenzymes in human metabolism. Human NAD⁺ levels decline by approximately 30-50% between the ages of 40 and 60, a decrease closely associated with hallmark features of aging such as diminished energy, reduced DNA repair capacity, and metabolic dysfunction.
Supplementing with NMN offers an efficient strategy for replenishing the body’s NAD⁺ pool. Oral administration of NMN offers superior bioavailability compared to direct NAD⁺ supplementation and is rapidly converted to NAD⁺ within cells.
🔬 NAD⁺ is an essential substrate for longevity proteins (Sirtuins) such as SIRT1, which regulate DNA repair, gene expression, and cellular stress responses.

NMN is synthesized through clean enzymatic biocatalysis, distinct from traditional chemical synthesis processes. This solvent‑free approach preserves nucleotide molecular integrity and directly meets the high purity demands of premium nutraceutical brands, achieves up to 99.99% purity.
NAD⁺ is a core coenzyme in glycolysis and the mitochondrial electron transport chain for ATP production. Higher NAD⁺ levels support more efficient mitochondrial energy generation, with significant implications for age-related fatigue, metabolic syndrome, and conditions affecting muscle and cognitive function.
NAD⁺ is an essential substrate for longevity proteins (Sirtuins) such as SIRT1, which regulate DNA repair, gene expression, and cellular stress responses. Higher NAD⁺ levels enable Sirtuins to function at full capacity, forming the core mechanistic basis of the longevity.
The brain is one of the most metabolically demanding organs, and NAD⁺ depletion is increasingly linked to the risk of neurodegenerative diseases. NMN supplementation is being investigated for its potential to support cognitive function, protect neurons, and maintain blood-brain barrier integrity.
Through enhanced cellular energy metabolism and its antioxidant effects, NMN supports improved vascular function, reduced blood pressure, and decreased arterial stiffness. Clinical studies are currently exploring its protective effects in patients undergoing coronary artery bypass grafting.
Research indicates that NMN has a positive effect on enhancing muscle function in middle-aged and elderly populations.
GeneHarbor led the drafting of China’s first NMN raw material group standard, establishing the technical benchmark for NMN quality across the entire industry.
GeneHarbor NMN has received FDA GRAS (Generally Recognized as Safe) certification.
GeneHarbor offers a comprehensive portfolio of NAD⁺ precursors and derivatives: NMN, NAD⁺, NADH, NADP – all derived from the same enzymatic production platform, helping B2B customers consolidate procurement of NAD⁺ pathway ingredients.
