Vitamin B12 supplementation in treating major depressive disorder: a randomized controlled trial.

ABSTRACT:

Background/objective

Recent literature has identified links between vitamin B12 deficiency and depression.We compared the clinical response of SSRI-monotherapy with that of B12-augmentation in a sample of depressed patients with low normal B12 levels who responded inadequately to the first trial with the SSRIs.

Results
