Vegans, vegetarians, and those who eat small amounts of animal-based proteins and meats often see a noticeable difference after vitamin B12 injections
By blocking NNMT, it shifts intracellular NAD+ and S-adenosylmethionine (SAM) levels, two cofactors tied to energy metabolism, redox balance, and gene regulation in laboratory models
The compound has been investigated in adipocyte-research and metabolic-disease research contexts where elevated NNMT activity has been linked to insulin resistance and adipose-tissue dysfunction
Extra-Intestinal Manifestations of Inflammatory Bowel Disease
Injection Frequency : For patients requiring frequent B12 injections, using a thinner gauge needle (especially for SC injections) can reduce tissue trauma and discomfort over time
However, the evidence base is still developing
