Contributing Factors

• There are many contributing factors that can lead to a vitamin D deficiency that you should be aware of. One of the body's primary sources of vitamin D is the sun, so reducing exposure to the sun can start to show signs of vitamin D deficiency. Young children who prefer to stay indoors and play video games, or older people who prefer to stay indoors as opposed to going outside, are at risk for vitamin D deficiency. In some cultures, the wearing of dark robes at all times due to religious beliefs can also prevent the sun's vitamin D from reaching you and this can cause the symptoms of vitamin D deficiency.
