Daily use depends on dose and individual risk. In preconception/early pregnancy planning or confirmed deficiency, daily supplementation is common—typically under clinician guidance. The operational risk is unnecessary high-dose, long-term use: it can create false reassurance, and in some cases may delay recognition of vitamin B12 deficiency. “More is better” is not a safe framework in clinical nutrition. A better approach is goal-based use (prevention vs treatment), a defined duration, and monitoring when indicated, followed by a deliberate decision to continue, adjust, or stop.
