what the evidence says
Nicotinamide riboside sits at the honest frontier of longevity science: multiple human trials confirm it raises NAD+ levels safely, but trials measuring things people actually care about, energy, muscle function, metabolic health, aging markers, have so far produced mostly null or marginal results. The mechanism is exciting; the payoff remains a hypothesis. Buy it as a bet on biology, not on demonstrated benefit.
Plain-language assessment of the human evidence. No cherry-picked citations.
