Vitamin D is a unique nutrient that is essential for a number of bodily functions. Vitamin D is required for maintaining strong bones, muscles, and teeth, cell growth control, proper immune functioning, neuromuscular functioning, and our overall health.

Vitamin D is a water soluble mineral that is formed in the skin when the skin is exposed to UVB rays in direct sunlight. The downside of this vitamin is that it is not found in many foods.

Below mentioned are the different sources of Vitamin D.
Sunshine is the best natural source of vitamin D. A regular dose of sunshine can increase your vitamin D intake greatly. When the sun’s rays hit our skin, it stimulates the production of vitamin D in the body. Around 30 to 60 minutes of walking in sun will provide you with the adequate vitamin D required for the day.
