Can supplements containing NMN, NAD+ and resveratrol really slow ageing? Here's what the evidence says

Evidence review by two Kingston University senior lecturers (Elbediwy in Cancer Biology & Clinical Biochemistry, Wehida in Genetics and Molecular Biology), published under The Conversation's editorial model (academic authors, editor-reviewed, disclosed expertise). Concludes human trials show NMN/NR raise NAD+-related blood markers but that 'recent reviews have not found convincing evidence that NMN or NR preserve muscle mass or function in older adults,' with outcomes closer to everyday aging (strength, cognition, frailty, biological age) 'much less clear'; that resveratrol has poor oral bioavailability and human trials 'have not shown convincing evidence that resveratrol slows ageing'; and that 'the marketing often turns "this affects a process associated with ageing" into "this supplement will keep you young".'
