3. It boosts your mood
If you are feeling a blue, especially during the winter months when exposure to the sun naturally decreases, it could be because you are suffering from a vitamin D deficiency. Several studies have revealed that the symptoms of Seasonal Affective Disorder (SAD) may be linked to low levels of vitamin D3. SAD is a mood disorder and the primary symptom is depression.
It occurs when exposure to sunshine is reduced. Studies suggest that the decreased levels of vitamin D3 may impact the levels of serotonin in the brain, a hormone that regulates the mood. By taking a vitamin D3 supplement or increasing your exposure to the sun, you could see a significant boost in your mood. You can also try eating more foods that are rich in vitamin D3, such as salmon, tuna, eggs, trout, and dairy products that have been fortified with the vitamin.
