Description
1-MNA Capsules | 1-Methylnicotinamide — NAD⁺ Metabolite Research
1-MNA (1-Methylnicotinamide chloride; NMN-Cl) is a naturally occurring metabolite of nicotinamide produced by the enzyme NNMT (nicotinamide N-methyltransferase). Once considered an inert urinary excretion product, recent research has established 1-MNA as a bioactive signaling molecule with anti-inflammatory, antioxidant, anti-thrombotic, and SIRT1-stabilising activities. These capsules (60mg per capsule, 60 capsules) provide a convenient oral research format.
Mechanism of Action
- SIRT1 stabilisation — reduces proteasomal degradation of SIRT1 protein in hepatocytes, increasing SIRT1 activity and downstream metabolic regulation
- NF-κB inhibition — prevents p65 nuclear translocation; inhibits TNF-α, IL-6, and IL-1β production
- Myokine activity — secreted by skeletal muscle during exercise to stimulate adipose tissue lipolysis and coordinate systemic energy use
- Prostacyclin pathway — exerts COX-2/prostacyclin-mediated anti-thrombotic and endothelial-protective effects
Research Areas
1-MNA capsules are studied in NAD+ biology, cardiometabolic research, NNMT pathway studies, and exercise physiology. Closely related to 5-Amino-1MQ capsules (direct NNMT inhibitor) for comparative NNMT pathway research.
