Ultraviolet (UV) Exposure Is Not the Answer. Our bodies manufacture vitamin D when the sun's ultraviolet B (UVB) rays interact with 7-dehydrocholesterol (7-DHC) present in the skin. However, we can produce only a limited amount of vitamin D from UVB.
Vitamin D got its nickname, the sunshine vitamin, because sun exposure helps promote vitamin D production in the body. This essential nutrient is also found naturally in a few foods such as oily fish (mackerel, salmon) and is used to fortify milk, baby formula, cereal, and juice.n addition to helping prevent arthritis, getting enough vitamin D may also lower the risk for other autoimmune diseases, cancer, heart disease, type 2 diabetes, bone fractures, depression, and even the flu.
