For most people today the answer is yes, you are not getting enough vitamin D. If you are listening to your dermatologist, you definitely are because he or she has a problem with the sun.

You do not want to be like them—you want to love the sun. More than three-fourths of people with a variety of cancers have low levels of vitamin D, and the lowest levels are associated with more advanced cancers so you really want to make friends with the sun.

A study has found that the number of people being diagnosed with vitamin D deficiency has tripled from 2008 to 2010 in the United States. Some researchers believe that up to 75% of the United States population may not be getting enough vitamin D (levels below 30 ng/ml).[1]

Essential for brain health, a strong immune system and weight management, Vitamin D3 is a fat-soluble vitamin that your body can get from sun exposure, food or supplements. However, nearly 50 percent of the population worldwide suffers from vitamin D3 deficiency.
