6Brain Benefits
Vitamin D plays a key role in overall brain health and nervous system. Taking vitamin D supplements might improve your mood and reduce the risk of depression. However, the exact mechanism is still unknown. A common theory is that the element would encourage the production of serotonin in the brain, a substance that contributes to the feelings of happiness and well-being. This benefit can be important during the winter when the synthesis of vitamin D from the sun would be extremely low. In addition, a low level of vitamin D in the body would be linked to sleep difficulties and increased sleepiness. [6]
