How do people become vitamin D deficient?
Vitamin D has been a topic of interest in the health-conscious world for some time. Deficiencies are more and more common as people spend more time working at jobs that require them to stay indoors. On top of that, many of us are aware that sun damage to the skin can cause many deleterious effects such as permanent aging and even cancers.
However, we also need natural sunlight in order to make adequate amounts of vitamin D. This is because the vitamin is activated into a form your body can use when UV rays of the sun enter your skin.
