<prompt> Ke kamano efe pakeng tsa khanya ea letsatsi le vithamine D?nan  <response>: Instruction in English: What is the connection between sunlight and vitamin D? . Response in English: Sunlight plays a crucial role in the production of vitamin D in the human body. When the skin is exposed to ultraviolet B UVB radiation from the sun, a form of cholesterol found in the skin 7-dehydrocholesterol is converted into vitamin D3, the active form of vitamin D. This vitamin D3 is then transported to the liver and kidneys where it is converted into its active form, calcitriol, which helps the body absorb calcium and maintain healthy bones. In addition to its role in bone health, vitamin D has many other important functions in the body, including supporting the immune system, regulating cell growth and reducing inflammation. Therefore, getting enough sunlight exposure is essential for maintaining optimal levels of vitamin D and supporting overall health. .
