Vitamin D is a fat-soluble vitamin that is essential for maintaining the health of bones and teeth. It plays a crucial role in the absorption of calcium and phosphorus from the gut, which are vital minerals for bone formation and maintenance. Vitamin D also supports the immune system, brain, and nervous system. The body produces vitamin D when the skin is exposed to sunlight, specifically ultraviolet B rays. It can also be obtained from certain foods such as fatty fish, fortified dairy products, and supplements. Deficiency in vitamin D can lead to bone disorders such as rickets in children and osteomalacia or osteoporosis in adults. Regular exposure to sunlight and a balanced diet can help maintain adequate levels of this important vitamin.
