Treatment with vitamin D has been shown to relieve symptoms of depression in a group of Swedish adolescents, a discovery that suggests vitamin D deficiency could be an easily treated cause of depression.
After a group of 54 depressed adolescents had their blood vitamin D tested it was discovered that 48 (89%) of them were vitamin D deficient. The vitamin D deficient group were then supplemented with vitamin D (4000 IU per day for the first month and 2000 IU per day for two more months).
Their vitamin D levels increased significantly from 41 nmol/L to 91 nmol/L and correlated with improvements in well-being. There were also significant improvements in depressed feelings, irritability, tiredness, mood swings, sleep difficulties, weakness, ability to concentrate and pain.
This report suggests that vitamin D deficiency should be investigated and treated in people suffering from symptoms of depression.
