4. Skin Color
One aspect of your life that you cannot change, but might be a cause of having low vitamin D levels is the color of your skin. If you have darker colored skin, you may need to get at least ten times much exposure to the sun to produce the same amounts of vitamin D as a person who has lighter skin does. The reason for this is because the pigment of the skin works as a natural sunscreen.
If you have more pigment in your skin, you may need to spend more time in the sun to make adequate amounts of vitamin D. If you do have darker skin, one of the ways to make up the difference in vitamin D levels is to make sure that you are eating a healthy diet that includes foods that are high in vitamin D. This can help your body get the amounts of the vitamin that it needs to avoid some of the health issues that may come from a vitamin D deficiency.
