Vitamin D has a lot of beneficial effects and a few of these includes it’s usefulness in building bone and muscle health, a few such features are elaborated here.

Vitamin D: types and metabolism

Vitamin D is popularly known as calciferol. It has been basically classified into five major types viz. Vitamin D1-D5. The most abundant and common in occurrence are Vitamin D2 known as ergocalciferol and Vitamin D3 (cholcalciferol). Vitamin D is a pro-hormone which converted into its most active metabolite 1,25-dihydroxy calciferol in the presence of enzymes.

Vitamin D and muscle health

In a research study conducted at Tufts University (USDA Human Nutrition Research Centre, America) the researchers clearly demonstrated that the muscle health is dependent on circulating Vitamin D levels in the body. Vitamin D receptors are present in muscle tissues and these receptors play in important role in absorption of Vitamin D in its active form. Higher level of Vitamin D in the muscle tissue had a direct positive relationship with improved musculo-skeletal function.

Natural food substances rich in Vitamin D

A 500-800 IU of Vitamin D3 intake on daily basis is the minimum basal level required . There are lot of supplements available commercially, and depending on proper advice of a physician, one of these could be selected to meet the body demand if the regular diet is not fulfilling it.
