The easy to notice symptoms for the deficiency of vitamin D are muscle aches, bone pain and weakness. For infants the bones will get soft due to low calcium level. Increased susceptibility to fracture of bones for example slight jarring or minor fall is enough to fracture the bone.

The main source of Vitamin D is exposure to the direct sunlight. The season of year, geographic latitude of the region, time of the day, weather of the region like cloudy day or not and use of sunscreen affect the amount of UV ray exposure and hence the synthesis of vitamin D in the body. The other source of vitamin D is the vitamin D rich food. It is essential for people who are not able to go out in the sun and synthesize vitamin D. The vitamin D rich diet is also recommended to old and dark skinned people. Nowson C & Margerison C (2002) has found out that many countries are fortifying foods such as milk products, bread, breakfast cereals and pastries with vitamin D2 and/or vitamin D3, to minimize the risk of vitamin D deficiency among the local inhabitants.

Adequate Intake levels of vitamin D suggested by the Institute of Medicine of the National Academy of Science (Algaecal, 2009) is 200 IU/day for ages ranging from infant to 50 years old, 400IU/day for ages 51-70 years old and 600IU/day over 70 years old people.

As mentioned earlier if people are exposed to sunlight for a longer time, there would be an equilibrium achieved between the generation and degradation of vitamin D, but it is not the case with vitamin D supplements. Excess intake of vitamin D can cause toxicity and high calcium level in blood (hypercalcemia).

As have been discussed, high usage of vitamin D fortified food will result in vitamin D toxicity and excess of deposits of calcium in liver resulting in fatal disorders. Hence, it is recommended that people should strike a balance between the consumption of food and exposure to sunlight regarding the intake of vitamin D. For example, dark skinned people and people who use veiled clothes should increase their vitamin intake though natural food and fortified food, as they are unable to synthesize vitamin D with the help of UVB present in natural sunlight. For other people it is suggested that they should be aware with the time of day and intensity of UVB, and then only should shed their clothes and bask in the sun.

There is increasing consideration in Australia about the diseases arising due to deficiency in vitamin D. It has been estimated that certain community of people might be more affected with the deficiency. According to Nowson et al (2004), dark skinned women who are veiled have 80% chances of having the deficiency. In addition, elder people have higher chances of having the deficiency. People who have skin condition are advised to be away from the sunlight also have higher chances of having the deficiency.
