Vitamin D also referred to as calciferol is a fat-soluble vitamin that is naturally present in a few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet UV rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D obtained from sun exposure, foods, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first hydroxylation, which occurs in the liver, converts vitamin D to hydroxyvitamin D [25 OH D], also known as calcidiol.

Help other people and contribute to the translation of the converter in your language! In order to convert some quantity of substance or active pharmaceutical ingredient please follow next steps:. If you entered, for example, , and obtained 0. Some substances have very small conversion factors in some directions, so the obtained results will be also very small. For convenience, under the rounded result unrounded one will display. International unit IU — In pharmacology, the international unit is a unit of measurement for the amount of a substance; the mass or volume that constitutes one international unit varies based on which substance is being measured, and the variance is based on the biological activity or effect, for the purpose of easier comparison across substances. International units are used to quantify vitamins, hormones, some medications, vaccines, blood products, and similar biologically active substances. Many biological agents exist in different forms or preparations e. The goal of the IU is to be able to compare these, so that different forms or preparations with the same biological effect will contain the same number of IUs. To do so, the WHO Expert Committee on Biological Standardization provides a reference preparation of the agent, arbitrarily sets the number of IUs contained in that preparation, and specifies a biological procedure to compare other preparations of the same agent to the reference preparation. Since the number of IUs contained in a new substance is arbitrarily set, there is no equivalence between IU measurements of different biological agents.

Individuals with a body mass index BMI of 30 or more have lower serum 25 OH D levels than individuals without obesity.

IU stands for International Units and is a standard measure used to quantify the biological activity or amount of certain vitamins. For the fat-soluble vitamins A, D and E, along with some B vitamins like folic acid, IU indicates the precise quantity needed to produce a specific biological effect for that vitamin type. Using IU allows standardized measurements so dosages and recommendations remain aligned globally across countries. The IU scale was established to account for variability in potency of different forms of certain vitamins.

Per equivalent microgram dose, 25 OH D 3 is three to five times as potent as vitamin D 3 [ 37 , 38 ]. A few studies have examined the effect of vitamin D supplementation on specific cancers. In a trial in Norway, men and women age 25—80 years mean age 62 years with prediabetes received mcg 20, IU vitamin D 3 or a placebo each week for 5 years [ ]. In some cases, fortified foods and dietary supplements are useful when it is not possible otherwise to meet needs for one or more nutrients e. No clinical trials have examined whether vitamin D supplementation can prevent the onset of MS, but several have investigated whether supplemental vitamin D can help manage the disease. It added that no national professional organization recommends population screening for vitamin D deficiency. Most trials of the effects of vitamin D supplements on bone health also included calcium supplements, so isolating the effects of each nutrient is difficult. Some substances have very small conversion factors in some directions, so the obtained results will be also very small. Read on to discover some crucial facts about IU and learn how to convert IU to mg or other metric units. The IU value is established by an international agreement.

This conversion is crucial in healthcare, as different medications and vitamins are often labeled in IU, while dosages are prescribed in mcg or other units.

Some mushrooms available on the market have been treated with UV light to increase their levels of vitamin D 2. Individuals who have difficulty absorbing dietary fat might therefore require vitamin D supplementation [ 63 ]. The Women's Health Initiative clinical trial randomized 36, postmenopausal women to receive IU vitamin D 3 plus 1, mg calcium daily or a placebo for a mean of 7 years [ 98 ]. The results of this analysis showed that 0. In addition to having an increased risk of vitamin D deficiency, people with these conditions might not eat certain foods, such as dairy products many of which are fortified with vitamin D , or eat only small amounts of these foods. If any health condition bothers you, consult a physician. However, most evidence indicates that vitamin D 3 increases serum 25 OH D levels to a greater extent and maintains these higher levels longer than vitamin D 2 , even though both forms are well absorbed in the gut [ ]. Vitamin D might also have anti-inflammatory, immunomodulatory, proapoptotic, and antiangiogenic effects [ 1 , 87 ]. This is a fact sheet intended for health professionals. The FNB committee that established DRIs for vitamin D found that the evidence was inadequate or too contradictory to conclude that the vitamin had any effect on a long list of potential health outcomes e. Below are brief descriptions of studies of vitamin D and its association with, or effect on, breast, colorectal, lung, pancreatic, and prostate cancers. Most people in the world meet at least some of their vitamin D needs through exposure to sunlight [ 1 ]. Vitamin D 2 is manufactured using UV irradiation of ergosterol in yeast, and vitamin D 3 is typically produced with irradiation of 7-dehydrocholesterol from lanolin obtained from the wool of sheep [ 13 , 31 ]. Observational studies indicate that greater body weights are associated with lower vitamin D status, and individuals with obesity frequently have marginal or deficient circulating 25 OH D levels [ ].
