Abstract

This article discusses the importance of vitamin D, vitamin D deficiency, and its natural sources.

Sources and Importance of Vitamin D

Sources of Vitamin D:

Some Important Facts About Vitamin D Are as Follows:

Long-Standing Vitamin D Deficiency: It results in decreased calcium levels, accompanied by impaired mineralization of the skeleton and proximal myopathy. Undermineralization of the bones leads to easy fractures.

Diagnosis of Vitamin D Deficiency:- The most specific screening test in otherwise healthy individuals is serum 25-hydroxy vitamin D levels.

Treatment for Vitamin D Deficiency:- The treatment includes supplementation with Vitamin D and Calcium.

It is important to note that self-administration of medications should be avoided, as vitamin D is a fat-soluble vitamin. Hence, the excess amount is not easily excreted out of the body and would lead to vitamin D toxicity. Hence, it is recommended to get treated under the supervision of your physician.
