High Purity NMN Beta Nicotinamide Mononucleotide Raw Material

1. Description

β-Nicotinamide Mononucleotide (NMN) is a direct product of nicotinamide phosphoribosyltransferase (NAMPT). As a key intermediate in the NAD⁺ salvage pathway, it establishes a homeostatic buffering system for the NAD⁺ pool within the cellular energy sensing network. Through SIRT3-dependent mitochondrial deacetylation, it restores metabolic flexibility and contractile function in aging cardiac muscle. As a competitive substrate for CD38, NMN reverses NAD⁺ depletion and inflammatory polarization in models of immune aging, thereby restoring immune homeostasis. By activating the AMPK/PGC-1α axis, it optimizes substrate selection of glucose and fatty acids in insulin-target tissues, enhancing metabolic flexibility. In neurodegenerative models, NMN protects axonal integrity from metabolic collapse by maintaining the NAD⁺/PARP balance. NMN is widely applied in the fields of aging biology, cardiovascular protection, immunomodulation, and neuroprotection research.

2. Application

(1) Cosmetics and Skincare Sector: Used as a functional ingredient in skincare product development, with several companies having completed the filing process for new cosmetic ingredients. Safety evaluations indicate that it is non-irritating at a 1% concentration and exhibits high biosafety. It is suitable for all types of cosmetics except sprays and lip products, and is primarily used in anti-aging and firming products.

(2) Functional Foods and Nutritional Supplement Research: Used as a dietary supplement ingredient to support cellular energy metabolism and in research related to delaying aging. It is currently sold through cross-border e-commerce platforms, but has not yet been approved in China as a new food ingredient or health food ingredient. In animal models, it is used to study its effects on improving glucose metabolism and lipid composition.

(3) Research on Neurological Disorders: Used in model studies of traumatic brain injury, ischemic brain injury, sepsis-associated encephalopathy, and neurodegenerative diseases. In brain injury models, it has demonstrated the ability to reduce neurological deficits and cognitive dysfunction.

(4) Immune Function Regulation Research: In cyclophosphamide-induced immunocompromised animal models, it is used to study immune-enhancing effects, including promoting macrophage phagocytic capacity, increasing antibody levels, and enhancing natural killer cell activity.

(5) Basic Research Applications: Used to investigate the binding motifs of RNA aptamers and the activation process of ribonucleases; serves as a reference standard for quantitative analysis and metabolic pathway studies. At the cellular and molecular levels, it is used to study mechanisms such as NAD+ metabolic regulation and SIRT activity modulation.

3. Main Efficacy

(1) NAD+ precursors and energy metabolism: As key intermediates in NAD+ synthesis, these compounds are converted into NAD+ upon entering cells, where they participate in hundreds of redox reactions, supporting energy metabolism and cellular function.

(2) Activation of the Longevity Protein SIRT1: By elevating NAD+ levels, they indirectly activate deacetylases such as SIRT1, influencing the expression of genes associated with oxidative stress, inflammatory responses, and circadian rhythms.

(3) Antioxidant and DNA Protection: They can increase the activity of DNA repair enzymes PARP-1 and SIRT1, helping to maintain genomic stability. In animal models, they have demonstrated the ability to alleviate oxidative stress.

(4) Metabolic Regulation: In animal models, it improves glucose metabolism abnormalities induced by a high-fat diet and regulates metabolism-related indicators.

(5) Neuroprotective Potential: It exhibits potential protective effects in animal models of neurodegenerative diseases such as Alzheimer’s disease, likely by improving neurovascular health and mitochondrial function.
