Vitamin B12 helps boost your energy and your bodys metabolism processes

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

Since Folic Acid and Vitamin B12 play leading roles in the methylation cycle, their close-knit relationship and their impact on homocysteine has some researchers suggesting that both should be taken as supplements to prevent neural tube defects

Of course, older adults, people over age 50 in particular, tend to have the lowest B12 levels, though vegetarians and those who have undergone gastric bypass surgery are also at a higher risk
