Your exposure to sunlight is limited.

Not many foods contain vitamin D, and vitamin D added to foods is not well regulated. In addition, even eating foods with added vitamin D may not give you enough of the vitamin for optimum health. The two most common causes of low vitamin D levels are lack of sun and not enough intake of vitamin D by mouth. Other causes of low vitamin D levels include the bodyâs inability to absorb enough vitamin D (intestines made shorter by surgery, gastric bypass, and intestinal diseases), chronic kidney disease, and liver failure (Table 1).
