5. You are experiencing increased feelings of depression.
Feeling “blue” every now and again isn’t unusual. In fact, we all feel a little down in the dumps sometimes; however, if you are finding that you are feeling more depressed than normal, it could very well be the result of a vitamin D deficiency. Chronic depression is a real and serious condition, and often, those who are diagnosed with it have a vitamin D deficiency.
While scientists are trying to pinpoint why low vitamin D levels are linked to depression, they think that it could be because this mineral impacts hormone – such serotonin – that play a vital role in regulating the mood. While researchers continue to study the link between vitamin D deficiency and depression, if you are feeling blue, taking a vitamin D supplement or eating more foods that are rich in vitamin D could help to lighten your mood.
