Our skin makes vitamin D from exposure to the ultraviolet rays in the sun. However, people living in temperate countries or in higher latitudes may get less UV exposure. Other complication arises like the fear of skin cancer which prompts many people to apply sun block which block the ability of the skin to make vitamin D. Another reason may be due to our busy working career. We are stuck in the office from morning to night leaving us with precious little time to be exposed to the sun. Lastly, some people for some reason may dislike going out in the sun.

That's why the diet rich in vitamin D is essential. Food that contains vitamin D include fish, eggs, milk and cereal. The problem is that our diet do not contain enough vitamin D and additional supplementation is required.
