In addition to limited absorption via the IF, the intake of high-dose supplements leads to passive diffusion, i.e., the vitamin can freely enter the bloodstream without IF binding and receptor uptake

By targeting NNMT an enzyme elevated in adipose tissue it alters downstream metabolic signaling independent of hormonal pathways
