Vitamin D and Depression

A growing body of literature has shown vitamin D to be a useful tool in the fight against depression, used alone or in combination with prescription antidepressant medications.(1,2,3) A recent study randomized 42 patients with depression to one of two groups: fluoxetine (Prozac) alone, or Prozac plus vitamin D (1500IU per day) for eight weeks. Using the Hamilton Depression Rating Scale as the primary outcome measure the study showed that vitamin D plus Prozac worked better than Prozac alone to improve depression symptoms. (4)
