Methionine is then converted into S-adenosylmethionine (SAM), which donates methyl groups in reactions catalyzed by methyltransferases, including DNA methylation, producing S-adenosylhomocysteine (SAH) that is converted back into homocysteine

When these pathways reactivate after deficiency, there may be increased demand for other nutrientsparticularly folate and iron
Biological Activities Observed in Studies Selective inhibition of nicotinamide N-methyltransferase (NNMT) Increased intracellular nicotinamide availability Modulation of NAD metabolic pathways Enhanced mitochondrial energy metabolism in experimental models Reduced adipocyte hypertrophy in preclinical studies Altered lipid metabolism and fatty acid utilization Investigation of cellular methylation pathways Potential influence on metabolic flexibility Evaluation of adipose tissue remodeling mechanisms Research applications in aging and regenerative biology Current evidence remains limited, and further well-controlled clinical studies are required to establish long-term efficacy and safety in humans
