The Journal of Clinical Endocrinology and Metabolism. Dark-skinned people are less efficient at making vitamin D because melanin in the skin hinders vitamin D synthesis. The conversion from ergosterol to vitamin D 2 follows a similar procedure, forming previtamin D 2 by photolysis, which isomerizes to vitamin D 2. Main article: , a childhood disease, is characterized by impeded growth and soft, weak, deformed that bend and bow under their weight as children start to walk.Next
High blood levels appear to be associated with a lower risk of death, but it is unclear if supplementation can result in this benefit.

Non-government organisations in Europe have made their own recommendations. Therefore, on top of the medicine the Doctor prescribed, have him go outside in the sun everyday for about 20 minutes. Vitamin D 3 is produced photochemically from 7-dehydrocholesterol in the skin of most vertebrate animals, including humans. The darker the skin, and the weaker the sunlight, the more minutes of exposure are needed.
Calcifediol is then converted by the kidneys to calcitriol, the biologically active form of vitamin D. If hypercalcemia is not treated, it results in excess deposits of calcium in soft tissues and organs such as the kidneys, liver, and heart, resulting in pain and organ damage. It is caused by supplementing with high doses of vitamin D rather than sunlight. One meta-analysis found a decrease in mortality in elderly people. The concentrations of vitamin D precursors produced in the skin reach an , and any further vitamin D produced is degraded. These are known collectively as calciferol.
