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.

Assessing vitamin D status by measuring serum 25 OH D concentrations is complicated by the considerable variability of the available assays the two most common ones involve antibodies or chromatography used by laboratories that conduct the analyses mcg to iu 56 ], mcg to iu.

Overall, the available research suggests that consuming higher amounts of vitamin D or taking vitamin D supplements does not promote weight loss. Few people near the equator develop the disease, whereas the prevalence is higher further north and south. They are all sorted in alphabetical order. However, because the extent and frequency of sunscreen use are unknown, the role that sunscreen may play in reducing vitamin D synthesis is unclear [ 1 ]. 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 [ ]. The flesh of fatty fish such as trout, salmon, tuna, and mackerel and fish liver oils are among the best sources [ 17 , 1 ].
