Ultraviolet (UV) rays from the sun, specifically UVB rays, are absorbed by the skin and trigger the synthesis of vitamin D. This process begins when UVB radiation converts 7-dehydrocholesterol, a compound in the skin, into previtamin D3, which is then transformed into active vitamin D (calcitriol) through further processes in the liver and kidneys. Adequate exposure to sunlight is essential for maintaining optimal vitamin D levels, which play a crucial role in bone health and immune function.
