Research demonstrates that individuals with recurrent aphthous stomatitis frequently present with lower B12 levels, and correcting this deficiency can reduce ulcer frequency and severity
Since the isolation of the cDNA in 1994, the work on the mammalian Molecular Biology of Methylenetetrahydrofolate Reductase (MTHFR) and Overview of Mutations/Polymorphisms MTHFR gene has resulted in significant advances in our understanding of its genomic organization, genetic variations and involvement in human disorders

Preclinical and clinical safety data includes [5] : No evidence of mutagenic activity, chromosomal aberrations, or micronucleus formation in genotoxicity studies 6-month chronic oral administration studies in rats showed no toxicological concerns 9-month studies in cynomolgus monkeys revealed general safety Six human clinical trials spanning 0.25 mg to 30 mg doses for up to 6 months No serious adverse events or withdrawals related to AOD9604 intake No anti-AOD9604 antibodies detected, indicating low immunogenic potential No changes in vital signs, physical examinations, electrocardiograms, or safety-related laboratory parameters Research Applications A Quick Review AOD9604 is a peptide compound that has shown potential in research related to lipid metabolism, energy balance, and tissue regeneration
However, there may be long-term adverse health effects from storing higher than normal levels of B12 in the body
