A number of studies support NAD + regeneration as a therapeutic strategy to benefit patients with obesity.[27] For examples, natural NAD + precursor activators such as nicotinamide riboside (NR) administered via dietary supplements to high-fat fed mice protected against diet-induced obesity, increased energy metabolism, and improved insulin sensitivity;[41] some of these effects were shown to be mediated by NAD + -dependent SIRT1 activation.[42] Similarly, systemic administration of NMN improved glucose tolerance and diet- and age-related insulin resistant conditions.[43, 44] However, dietary supplemental NAD + precursors (e.g., NR, NMN) require chronic administration and/or very high pharmacological doses to achieve physiologically beneficial enhancements in the NAD + levels, which potentially limit use in humans.[27] It could be predicted that combined administration of sub-maximal doses of dietary supplements and NNMT inhibitors that function as activators of NAD + might produce synergistic improvements in diet-induced obesity, and reduce adverse effects associated with chronic high-dose administration of dietary supplemental NAD + precursors

Clinical Assessment: Additional testing may be recommended where appropriate
When there is a lot of B12 floating around, the bacteria dont have to waste resources and, instead, can focus on trying to pimple you up
The recommended daily intake of B12 for adults is 2.4 mcg
Currently, there is no confirmed evidence of side effects
The lab work tells them apart
