Enhancing women's mood and energy: a research-based program for subthreshold depression using light, exercise, and vitamins.

The prevalence and clinical significance of subthreshold forms of depression with sequelae comparable to major depression have been recently described in the literature; however, research on effective treatment is rare. A new intervention program that combines a specific regimen of light, exercise, and vitamins is effective in improving women's mood and overall sense of well-being. This program is well suited to many patients who present with somatic and psychological symptoms consistent with subthreshold depression.
