Mapping of several bone diseases onto levels of vitamin D (calcidiol) in the blood [6] Normal bone vs. osteoporosis. Vitamin D deficiency is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D in the blood, which is the most accurate measure of stores of vitamin D in the body.
While some studies have found that vitamin D 3 raises 25(OH)D blood levels faster and remains active in the body longer, [44] [45] others contend that vitamin D 2 sources are equally bioavailable and effective for raising and sustaining 25(OH)D. [46] [47] If digestive disorders compromise absorption, then intramuscular injection of up to ...
