what is vitamin d used for

Vitamin D is used for various purposes in the body. It promotes calcium absorption in the gut, maintains adequate serum calcium and phosphate concentrations, and enables normal bone mineralization, thus preventing conditions like rickets in children and osteomalacia in adults. Together with calcium, vitamin D also helps protect older adults from osteoporosis. Additionally, it has other roles in the body, including reducing inflammation, modulating cell growth, neuromuscular and immune function, and glucose metabolism. Some studies suggest that vitamin D might inhibit carcinogenesis, slow tumor progression, and have anti-inflammatory, immunomodulatory, proapoptotic, and antiangiogenic effects. It is also essential for maintaining healthy bones, regulating inflammation, and supporting immune function
