Abstract in brief

  • Vitamin B12 is essential for human health, but its relationship with mortality rates isn't fully understood, prompting a systematic review and meta-analysis to study this connection.
  • The analysis included 22 cohort studies with over 92,000 participants, revealing that higher serum vitamin B12 levels were associated with increased all-cause mortality, particularly in older adults.
  • While high vitamin B12 (>600 pmol/L) showed a strong correlation with all-cause and cardiovascular mortality, the evidence for its link to cancer mortality was inconclusive.
