UV light stimulates the production of which vitamin?

UV light plays a crucial role in the synthesis of Vitamin D in the human body. When the skin is exposed to ultraviolet rays, specifically UVB, a chemical reaction occurs that converts a compound called 7-dehydrocholesterol into previtamin D3. This substance is then transformed into active Vitamin D3, which is essential for various bodily functions, including calcium absorption and bone health.

Vitamin D is often referred to as the "sunshine vitamin" because it is produced in response to sunlight. This natural process underscores the importance of UV light in maintaining adequate levels of Vitamin D, which can have a significant impact on overall health.
