As a recent scientific review explains, 4 Owing to its size and charged nature, NAD+ cannot passively pass through cellular membranes, including the plasma membrane. ...this probably occurs indirectly through the generation of NAD+ degradation products, such as NMN, NR or NAM, which act as precursors. In other words, NAD+ taken orally must first be broken down into these smaller molecules before it can re-enter cells and contribute to NAD+ synthesis
