Vitamin D is thought to regulate the disturbances of central nervous system functions that have been linked to depression. Cross-sectional studies have also observed a link between symptoms of depression and a deficiency in vitamin D.
This meta-analysis of the link between supplementation with vitamin D and depression included results from 41 studies worldwide. These studies have looked at the effectiveness of vitamin D in relieving symptoms of depression in individuals through randomized placebo-controlled studies in different populations.
The studies included those performed in depressive individuals, in the general population, and individuals with a variety of physical conditions. The meta-analysis results reveal that vitamin D supplementation works more effectively compared to a placebo in relieving symptoms of depression. There were significant differences in the vitamin D doses used, but the vitamin D supplement was generally 50-100 daily micrograms.
