For skeletal health, both Vitamin D& Calcium play a vital role

For optimal skeletal health, both Vitamin D& Calcium play a vital role. Vitamin D triggers calcium homeostasis. Low bone mass, osteoporosis, high fracture rates are some of the consequences of calcium and Vitamin D deficiency. The main source of Vitamin D is sunlight and that of calcium is dairy products.

Metabolism of Vitamin D

Vitamin D is a combined form of Ergocalciferol (Vitamin D2) and Cholecalciferol (Vitamin D3). Irradiated yeast and fungiareVitamin D2 sources. Vitamin D3 is produced in the skin and can be derived from food sources as well.

When our skin is directly exposed to ultraviolet B radiation within a wavelength of 290 to 315 nm, it converts 7-dehydrocholesterol to pre-vitamin D3. Skin color, sunscreen products, age, latitude, season, and time are some factors affecting the natural method of Vitamin D3formulation.

Both the forms of Vitamin D get bonded with a Vitamin D-binding protein. This is transported in the liver and kidney, which is absorbed in the nucleus and Vitamin D-dependent genes. (1)

Metabolism of Calcium

Vitamin D optimizes calcium and phosphorus absorption in the body for the composition of the bone mineral matrix. Across the intestine, there is a transcellular and paracellular pathway, through which the calcium is transported. There are many calcium sources, where the body derives the required amount of this micronutrient, however, excessive intake may result inside effects. (2)

Role of Vitamin D

The only role of Vitamin D is to absorb calcium and phosphorus from different sources and thus, maintain skeletal health. Without enough Vitamin D, hormone calcitriol is not produced. In such a situation, the body suffers from calcium deficiency. This ceases the formation of new bones and makes existing bones feeble.
