Cholecalciferol is a form of vitamin D which is naturally synthesized in skin and functions as a pro-hormone, being converted to calcitriol. This is important for maintaining calcium levels and promoting bone health and development. [4] As a medication, cholecalciferol may be taken as a dietary supplement to prevent or to treat vitamin D ...
Synthesis of vitamin D in nature is dependent on the presence of UV radiation and subsequent activation in the liver and the kidneys. Many animals synthesize vitamin D 3 from 7-dehydrocholesterol, and many fungi synthesize vitamin D 2 from ergosterol. [46] Vitamin D 3 is produced photochemically from 7-dehydrocholesterol in the skin of most ...
The name 25(OH)D refers to any combination of calcifediol (25-hydroxy-cholecalciferol), derived from vitamin D 3, and ercalcidiol (25-hydroxy-ergocalciferol), [1] derived from vitamin D 2. The first of these (also known as 25-hydroxy vitamin D3) is made by the body, or is sourced from certain animal foods or cholecalciferol supplements.
In this article, we’ll highlight six foods that offer more vitamin D than an egg, along with tips on how to incorporate them into your meals. 1. Trout . 3 ounces = 645 IU Vitamin D (108% Daily ...
7-Dehydrocholesterol (7-DHC) is a zoosterol that functions in the serum as a cholesterol precursor, and is photochemically converted to vitamin D 3 in the skin, therefore functioning as provitamin-D 3. The presence of this compound in human skin enables humans to manufacture vitamin D 3 (cholecalciferol).
Cholecalciferol (vitamin D 3) is synthesized in the skin after exposure to the sun or consumed from food, usually from animal sources. [46] Ergocalciferol (vitamin D 2) is derived from ergosterol from UV-exposed mushrooms or yeast. [46] When produced industrially as supplements, vitamin D 3 is typically derived from lanolin in sheep wool.
