                                According to scientific research, NMN exists in two stereoisomers, alpha ($\alpha$) and beta ($\beta$), but only the beta ($\beta$) form is biologically active and can be converted into NAD+ in the body. This distinction is the critical difference between NMN and beta NMN, with the unqualified term 'NMN' often implying the active beta version in a biological context.
