This research examines whether vitamin B12 supplementation benefits individuals without a proven deficiency.
Explored existing health authority guidance on routine testing for vitamin B12 deficiency.
Reviewed prevalence data from high-income countries and settings with limited B12 access.
Analyzed effectiveness of various supplementation regimens and their impacts on fatigue, mood, cognition, and cardiovascular health.
Supplementation did not show consistent benefits in fatigue, mood, cognition, or cardiovascular outcomes in populations without clear deficiencies.
Some benefits were observed in specific subgroups, such as individuals with hyperhomocysteinemia.
Observational studies showed an association between higher B12 levels and increased malignancy risks, though causality was not established.
