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.

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. The IU should not be confused with the enzyme unit, also known as the international unit of enzyme activity and abbreviated as U. International unit IU — Internationally agreed-upon standards are necessary to compare the potency of various biologically assayed compounds in terms of their activity. If it is not possible to purify chemically the substance to be bioassayed, a stable standard solution has to be employed for comparison.

For men with prostate cancer, mcg to iu, whether vitamin D supplementation lengthens cancer-related survival is not clear. We need to know the exact value of IU per mcg that should be applied in a given situation.

A man who had been taking vitamin D supplements for at least nine months died of a condition linked to excessive levels in the blood. The packaging didn't make clear the risks of taking too much, a UK coroner's report said. David Mitchener, 89, a retired businessman from the UK, was admitted to the hospital on May 10 with hypercalcemia, a condition in which calcium levels in the blood are too high. It can weaken bones and cause kidney problems, such as kidney stones, as well as heart problems. Vitamin D helps the body absorb calcium, so if we have too much, it can lead to a buildup of calcium. When doctors tested Mitchener's vitamin D levels, the results showed they were at the maximum level recordable by the lab, the report said.

If you've ever checked a vitamin or mineral supplement label, you've probably seen these three letters: mcg. Either on the front of the label or within the Supplement Facts panel, next to an ingredient like Vitamin D3, you'll see, for example, "50 mcg. Understanding how vitamins or minerals are measured can help you understand how much of a certain nutrient you are taking — a key consideration for anyone looking to make informed choices when it comes to their supplement routine. Now, let's break down exactly what a microgram is.

Vitamin D supplementation did not lower the risk of total fractures, hip fractures, or nonvertebral fractures as compared with placebo. International units converter v. Most of the studies described in this section measured serum 25 OH D levels using various methods that were not standardized by comparing them to the best methods. Since the number of IUs contained in a new substance is arbitrarily set, there is no equivalence between IU measurements of different biological agents. The mean age of all participants was Another meta-analysis of genetic studies in , participants primarily adults found that a low vitamin D status increased blood pressure and hypertension risk in people with genetic variants associated with low endogenous production of 25 OH D [ ]. One clinical trial randomized Black women age 60 years and older mean age Among postmenopausal women and older men, many clinical trials have shown that supplements of both vitamin D and calcium result in small increases in bone mineral density throughout the skeleton [ 1 , 74 ]. Some people with MS eventually lose the ability to write, speak, or walk. Ready-to-eat breakfast cereals often contain added vitamin D, as do some brands of orange juice, yogurt, margarine, and other food products. The USPSTF stated that, due to insufficient evidence, it was unable to assess the balance of benefits and harms of supplemental vitamin D to prevent cancer [ ]. Season, time of day, length of day, cloud cover, smog, skin melanin content, and sunscreen are among the factors that affect UV radiation exposure and vitamin D synthesis. The IU value is established by an international agreement. One reason is that sun exposure affects vitamin D status, so serum 25 OH D levels are usually higher than would be predicted on the basis of vitamin D dietary intakes alone [ 1 ]. Thiazide diuretics e.

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. The results showed that baseline serum 25 OH D levels were inversely associated with total number of CVD events including myocardial infarction, ischemic heart disease, heart failure, and stroke and mortality risk [ ]. Season, time of day, length of day, cloud cover, smog, skin melanin content, and sunscreen are among the factors that affect UV radiation exposure and vitamin D synthesis. Some people take very high doses of vitamin D supplements. One study, for example, tested 25 OH D levels in 1, women in Finland an average of 9 years before their MS diagnosis and compared their outcomes with those of 2, similar women who did not develop MS [ ]. In addition, although 25 OH D levels rise in response to increased vitamin D intake, the relationship is nonlinear [ 1 ]. In contrast to observational studies, clinical trials provide little support for the benefits of vitamin D supplementation for glucose homeostasis. Total vitamin D intakes were three times higher with supplement use than with diet alone; the mean intake from foods and beverages alone for individuals age 2 and older was 4. Decimal places. The second hydroxylation occurs primarily in the kidney and forms the physiologically active 1,dihydroxyvitamin D [1,25 OH 2D], also known as calcitriol [ 1 ]. The impact of this form on vitamin D status is an emerging area of research.
