Hair Loss

Hair loss is another problem faced by people lacking in vitamin D. Severe hair loss indicates nutrient deficiency in the body and should be treated although some hair loss is also related to stress factors. Alopecia areata is a disease that causes severe hair loss and is associated with soft bone causing disease called rickets.


Vitamin D deficiency has also been linked with depression. Some studies have shown improvements in mood if the levels are improved after taking a supplement.

Impaired Wound Healing

Vitamin D deficiency slows down the healing process of wounds as vitamin D is responsible for formation of new skin production. Also, the body’s healing ability is affected if the body is unable to fight off infections and inflammation.

Back Pain

Lower back pain and bone pain are common symptoms of vitamin D deficiency as lower levels of the vitamin can make the absorption of calcium inefficient. The likelihood of suffering from leg pain and joint pain increases twice if you have a deficiency of vitamin D.

The cause of vitamin D deficiency can particularly be limited exposure to sunlight. Also, dark skin unables vitamin D production because of the melanin pigment. People may also face a deficiency as they age if the kidneys do not convert vitamin D into its active form.

Natural sources of vitamin D are mostly animal based which is why vegan people can have a deficiency of vitamin D. Moreover, digestive diseases can also cause insufficient absorption of vitamin D in the body. Also, obese people can have this deficiency.

Tests for Diagnosing Vitamin D Deficiency

A blood test can help in the diagnosis of vitamin D deficiency. Blood levels in between 20 ng/ml and 50 ng/ml are adequate whereas below 12 ng/ml indicates vitamin D deficiency.
