![]() Vitamin D Council . In this article, we’ll teach you a little about this process, and how vitamin D works in the body. Where does vitamin D come from? Vitamin D. When you expose your skin to ultraviolet B, something called “photolysis” happens of a chemical called 7- dehydrocholesterol, which turns it into previtamin D. This happens on the outermost layer of your skin, called the epidermis. This previtamin D. After you make vitamin D. Vitamin D, when taken as food or supplement, is absorbed in your intestine. From here, vitamin D is collected by that binding protein and taken to the liver, too. Now what does vitamin D do? In the liver, vitamin D is turned into a chemical called calcidiol. The process it goes through is called “hydroxylation.” This chemical the liver makes is called a number of things, including: calcidiol. OH)D2. 5- hydroxyvitamin Dvitamin D levelblood vitamin Dvitamin D serum concentration. We like to call it either 2. OH)D or “vitamin D level” because we think it’s easiest to remember and understand. Basically, it’s believed that this chemical that the liver turns vitamin D into is how your body stores its vitamin D and provides vitamin D for your body. When your doctor measures your vitamin D, this is what he is measuring, 2. OH)D, or sometimes he/she will just call it your vitamin D level. ![]() Diagnóstico, prevención y tratamiento de la hipovitaminosis D. Coordinador: Ariel Sánchez.

Deficiência de vitamina D: uma perspectiva global. Francisco Bandeira I; Luiz Griz I; Patricia Dreyer. Clinical Practice. Stage IV Chronic Kidney Disease. Hanna Abboud, M.D., and William L. Henrich, M.D. N Engl J Med 2010; 362:56-65 January 7, 2010 DOI: 10.1056. At this point, this new form of vitamin D . It’s simply making itself available for tissues all over the body. What do your tissues do with this 2. OH)D? They take 2. OH)D and turn it into a chemical called 1,2. OH). This process is also called “hydroxylation.” This chemical is called a number of things, including: Calcitriol. D1,2. 5(OH). When vitamin D is in this final form, 1,2. OH). This is really important for your daily survival, and your body is just about never out of 1,2. OH). Sometimes doctors and scientists call this vitamin D’s “endocrine function.”When other tissues in your body turn 2. Measurement of intact parathyroid hormone (iPTH), ionized calcium (iCa 2+), and 25-hydroxyvitamin D (calcidiol) can help discriminate between the various causes of. ![]() OH)D into 1,2. 5(OH). Tissues like you brain, skin, breast, colon, cardiac muscle, immune cells, and more all make 1,2. OH). Sometimes doctors and scientists call this vitamin D’s “autocrine function.”Sometimes doctors mistakenly measure 1,2. OH). The problem with this, though, is that when you measure 1,2. OH). And how much your kidney produces is dependent on a lot of things, like how much calcium and PTH you have in your blood at that moment, and not how much vitamin D you have stored. How does “activate vitamin D” work? The last key piece to the vitamin D system is what is called the “vitamin D receptor” (VDR). When 1,2. 5(OH). These bounded VDRs can now tell local genes how to express themselves. When genes express themselves, they are expressed in proteins and enzymes. These proteins and enzymes tell the body what to do, how to express itself and how to function. When you get enough vitamin D, this is a smooth process and allows cells all over your body to communicate properly. When you don’t get enough vitamin D, this process is broken down a little bit, and cells may not communicate quite as well. How this affects diseases and conditions, researchers are still trying to figure out. How does vitamin D work to make sure you have the right calcium balance? Vitamin D plays an important role in making sure your body and blood have the right amount of calcium. ![]() Two hospitalized chronically ill patients with unrecognized vitamin D deficiency, hypocalcemia, and hypophosphatemia are presented below.Depending on how much calcium you have in your blood, glands called the parathyroid will tell your kidney to either produce or not to produce more 1,2. OH). Without enough vitamin D, your body might not produce as much 1,2. OH). Without getting adequate calcium in your diet and being able to adequately absorb it, you can’t have good bone health. See our Parathyroid glands and vitamin D page for more information on how vitamin D works with calcium and parathyroid. How does the vitamin D system work outside of bone health? Vitamin D’s function outside of calcium balance is a relatively new discovery, and it is what has doctors and scientists enthusiastic about vitamin D. As mentioned above, tissues all over your body produce 1,2. OH). How they use this 1,2. OH). Getting enough vitamin D, however, ensures that tissues have all the vitamin D they need to produce as much 1,2. OH). In each condition, we explain how vitamin D may act and play a role in that condition. References. Jones G and Prosser DE. The Activating Enzymes of Vitamin D Metabolism (2.
