Features & Benefits: Intended to provide nutritive support for calcium and phosphorus absorption and utilization Essential for normal bone and teeth development Intended to provide nutritive support for normal immune function and cell growth Natural chole Facts About Vitamin D Vitamin D, also known as calciferol, is popularly referred to as the "sunshine vitamin." Vitamin D can be synthesized in the body with appropriate exposure to the ultraviolet rays of the sun (a process called photobiogenesis). This process requires cholesterol, so the resulting fat-soluble vitamin form is known as "cholecalciferol." The synthesized vitamin enters the bloodstream and makes its way to the liver, where it is converted to 25-hydroxycholecalciferol. From there, much of it goes to the kidneys for the final conversion to 1,25 dihydroxycholecalciferol. In this final form, the body uses Vitamin D to help calcium absorption in the intestines, and to release calcium stores from the bones when necessary to maintain calcium blood levels. Within the small intestine, Vitamin D helps calcium to be absorbed, rather than excreted, by activating a process in the mucous membranes that actively transports calcium to the blood. It similarly helps the absorption of phosphorus, another bone-building mineral. In the blood, Vitamin D either signals the kidneys to re-absorb calcium and phosphates as necessary, or causes the bones to release necessary amounts of calcium and phosphorus into the blood stream. With the help of parathyroid hormone (PTH), this homeostatic stabilizing process helps to maintain many body functions. If blood calcium is not kept stable, disturbances of nerve function can result in muscle twitching and sp
