1α-Hydroxyvitamin D 5 is a chemical derivative of vitamin D 5.The motive to study 1α-hydroxyvitamin D 5 as a potential pharmaceutical drug stemmed from the tendency of calcitriol, a natural metabolite produced in the kidney, to cause toxic hypercalcemia in patients when dosed at concentrations needed to interrupt prostate cancer cells' cycle and stimulate apoptosis.
While serum low 25-hydroxyvitamin D status has been associated with a higher risk of cancer in observational studies, [101] [102] [103] the general conclusion is that there is insufficient evidence for an effect of vitamin D supplementation on the risk of cancer, [2] [104] [105] although there is some evidence for reduction in cancer mortality.
The liver is required to transform vitamin D into 25-hydroxyvitamin D. This is an inactive metabolite of vitamin D but is a necessary precursor (building block) to create the active form of vitamin D. [1] The kidneys are responsible for converting 25-hydroxyvitamin D to 1,25-hydroxyvitamin D. This is the active form of vitamin D in the body.
Plasma osmolality measures the body's electrolyte–water balance. [1] There are several methods for arriving at this quantity through measurement or calculation. Osmolality and osmolarity are measures that are technically different, but functionally the same for normal use.

A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). [2] It is determined by collecting data from vast numbers of laboratory tests. [citation needed]
A new study found that people who have had COVID-19 are more likely to develop chronic fatigue syndrome. A researcher and doctor weigh in on the symptoms to watch for.
Normal doses are safe in pregnancy. [7] It works by increasing the amount of calcium absorbed by the intestines and reabsorbed by the kidneys. [6] Food in which it is found include some mushrooms. [8] Ergocalciferol was first described in 1936. [9] Ergocalciferol is available as a generic medication and over the counter. [6]
