Case series, such as that described by Lotz-Havla et al
Notable recent developments include the first preclinical study demonstrating NNMT inhibition improves cardiac function and reduces fibrosis in a heart failure model (Li et al., 2025), a comprehensive review of NNMT as a therapeutic target for neurodegenerative disorders (Liu et al., 2025), and emerging evidence that NNMT inhibition counteracts tubular senescence and fibrosis in chronic kidney disease
Patient Safety Patient safety should always be a priority
Finally, dietary habits and overall lifestyle can also influence B12 absorption
Because it avoids those receptors, AOD 9604 does not elevate IGF-1 levels, does not affect blood sugar regulation, and does not carry the risks associated with exogenous growth hormone use
Overall, although limited, the evidence suggests a benefit of methyl-B12 for children with ASD
