One study reported that vitamin B12 deficiency was associated with twice the risk of severe depression (4)
Each subgroup included three to five animals
The following data were collected: publication year, country and continent, study setting (e.g., hospital, private practice, academic clinic), sample size, age range, mean age, study design, population characteristics, intervention details, outcomes, and effect measures (e.g., serum B12 levels)
When adverse effects do occur, they are usually mild and transient, often related to the route of administration rather than the vitamin itself
