Mood changes such as irritability, depression, or anxiety, as well as numbness or tingling in the hands and feet, can also be linked to low B12 levels
Selective and membrane-permeable small molecule inhibitors of nicotinamide N-methyltransferase reverse high fat diet-induced obesity in mice (in Eng)
It is used in research settings to investigate NNMT-dependent metabolic pathways, including relationships to NAD+ metabolism, cellular energy regulation, and metabolic homeostasis in experimental models
GH has also been used experimentally in patients with short bowel syndrome to lessen the requirement for intravenous total parenteral nutrition
Additionally, the issue is exacerbated by traditional laboratories setting the 'normal' range too low, which may result in undiagnosed B12 deficiencies
