Before any supplement, ask three simple questions: do I actually have a shortfall, could food fix it, and is the evidence solid? In most cases, sleeping better and eating a more varied diet do more for health than stacking capsules.

Source: Dr. Rupy Aujla (Doctor's Kitchen), a UK general practitioner specializing in culinary nutrition. Evidence type: a synthesis built on major trials (VITAL, Physicians' Health Study II, the BMJ's 2020 systematic review) showing no net clinical benefit from most vitamins and minerals in adults without a measured shortfall. The three-question framework (real shortfall, food alternative, strength of evidence) lines up directly with the food-first principle documented in the supplement literature: multivitamin users generally already eat better, which skews observational studies in their favor without the pill itself doing much of the work. Ranking sleep and food above supplements in the hierarchy of health levers is consistent with the available evidence overall. Direction: associational for most of the self-reported benefits among supplement users (healthy-user bias).
