What Is 25 Hydroxy Vitamin D?

[zeev]

There are two main types of vitamin D: D2 and D3. Vitamin D2 is found in fortified foods, some plants, and supplements, and D3 is found naturally in food sources such as tuna and salmon, and is produced through the exposure of the skin to sunlight or ultraviolet (UV) rays. D3, also known as calcidiol, is more easily converted to the active 25 hydroxy vitamin D and is more efficiently used for body processes.Once vitamin D has been transformed into the active 1,25 dihydroxy vitamin D in the kidneys, the hormone helps to absorb calcium in the body and regulate levels of phosphate. It is involved in bone growth, mineralization and remodeling, nerve and muscle function, and the immune system, and it prevents hypocalcemic tetany. Rickets, a disease that causes bone deformity and stunted growth, and osteomalcia, a bone-thinning disease that causes muscle weakness, pain, and fractures, both are caused by a vitamin D deficiency.
