Vitamin D & Depression (2008)
Dutch researchers compared vitamin D levels with mood in a study of 1,282 elderly people. They found that vitamin D levels were 14% lower in those with depression. Measures of parathyroid hormone showed that this hormone was 5-33% higher in elderly individuals with depression. Depression severity was also observed to be associated with serum vitamin D levels and parathyroid hormone levels.
Vitamin D is known as the ‘sunshine vitamin’ because the primary source of it is from the action of the sun on your skin.
