A vitamin essential for the growth of teeth and bones. There are two forms of vitamin D - 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D. The body obtains vitamin D in two ways. Generated by the skin when it meets sunlight and ingested with food and supplements. The main role of vitamin D is to help regulate blood levels of calcium, phosphorus, and magnesium. Without vitamin D bones are soft and can't repair themselves as normal. Vitamin D can also help the growth of other tissues and can also help regulate the immune system. It appears that this vitamin is quite an important one.
