What is a common name for vitamin D?

• A. Sunshine vitamin
• B. Energy vitamin
• C. Bone vitamin
• D. Immune vitamin

Answer: (A)

Vitamin D is commonly called the Sunshine vitamin because the body can produce it when the skin is exposed to sunlight. UVB rays convert a cholesterol precursor in the skin into vitamin D3, which is then activated in the liver and kidneys. This nickname highlights sunlight as a natural source of the vitamin, a distinction not shared by the other suggested names. Vitamin D is important for calcium absorption and bone health, and it also supports immune function. While it can be obtained from some foods and supplements, the link to sunlight is the defining reason this is the usual name.
