An intramuscular B12 shot goes directly into your muscle fibers for 100% systemic absorption and immediate efficacy
The research record is based on animal models and mechanistic reasoning
Because NNMT activity has been linked with obesity-related metabolic patterns, NNMT inhibition is studied as a way to improve metabolic efficiency in adipose tissue
Do not take Vitamin B12 Injection if you: Are allergic to Vitamin B12, cobalt, or any other ingredients in the tablets Have hereditary optic atrophy (loss of some or most of the nerve fibers in the optic nerve) Vitamin B12 Tablets should not be used in newborns
Route changes exposure, and rat data cannot provide a safe conversion
Based on preclinical (animal and cellular) data only, inhibition of NNMT by 5-Amino-1MQ is theorised to: Raise intracellular NAD+ levels Activate SIRT1 and other sirtuins (proteins linked to metabolic regulation) Reduce fat cell (adipocyte) size and proliferation Improve insulin sensitivity These effects have been demonstrated in mouse models (Neelakantan et al., 2019), but robust human clinical trial data are currently absent
