Worldwide, 280 million people experience clinical depression each year, according to the World Health Organization (WHO). Researchers at the University of Eastern Finland have discovered a connection between depression and vitamin D in a new study.
A meta-analysis was conducted earlier for this study. A meta-analysis is a type of analysis that brings together findings from various prior studies and makes inferences based on the data after statistically analysing it.
53,235 participants’ results from this meta-analysis were included. Both people with and without depression were participants in this study.
‘These findings will encourage new, high-level clinical trials in patients with depression in order to shed more light on the possible role of vitamin D supplementation in the treatment of depression,’ says Tuomas Mikola, doctoral researcher and lead author at the University of Eastern Finland
The individuals’ average daily vitamin D consumption ranged from 50 to 100 micrograms. Even placebo medications were administered to some of the subjects. It was discovered that giving vitamin D to depressed volunteers was more beneficial than giving them placebo medications.
In their newly published work, researchers state that their findings ‘indicate that vitamin D supplementation has positive benefits in both persons with major depressive disorder as well as in those with milder, clinically relevant depressed symptoms.’
