It is well-known that several studies have suggested that the symptoms of SAD may be due to changing levels of vitamin D3, which may affect serotonin levels in the brain. Although vitamin D supplementation may improve mood, vitamin D is only a small, but critical, part of treatment as depression has myriad causes.

Thank you "very much" Noor Shaker, scientific information and very important with appreciation

Greetings and appreciation

The results of a tecent study showed that there is a relationship between low levels of vitamin D in the blood and depression. However, the research didn't show whether vitamin D was the cause or effect of depression. This research also found that taking vitamin D, particularly in large amounts, improved the symptoms of depression.

Incidents of Seasonal Affective Disorder (SAD) more prevalent in the northern latitudes can be treated with phototherapy, i.e., exposing the patient to the correct wavelengths of light similar to the solar spectrum. Knowing that skin exposure to sunlight results in Vitamin D production, there is no doubt that a correlation exists between low Vitamin D levels and depression incidents.

Elevation of intrcellular calcium in neurons promotes depression. Since vitamin D is essential to keep intra neuronal calcium in low levels, development of depression would be enhanced in vitamid D deficiency. Please refer to (Pharmacol Rev. 2017 Apr;69(2):80-92).
