Fundamentally vitamin D is used in the body for healthy bone development but like most vitamins it plays a part in multiple biochemical processes that our bodies depend upon.
Vitamin D can help with skin conditions like psoriasis because it is known to have a regulatory effect on the peptide responsible for it called cathelicidin.
The word "vitamin" is a contraction of "vital amine" (back when it was thought they were all amines; vitamin D happens to not be). The word "vital" was used in the sense of "if you don't have them, you will cease to be vital, i.e. you will die."
It turns out your body can make some of them... vitamin D is one of these; your body can make it using cholesterol as a starting material. However, it's necessary to get some exposure to sunlight in order to do so. If you work outside, this probably isn't a problem; if you don't like the big room with the bright light and the blue ceiling, it could be, and you need to get some from your diet or supplements.
Vitamin D is actually toxic in very large doses.
Vitamin D is formed in your skin when the skin is exposed to UV
The skin produces vitamin D when exposed to sunlight. Vitamin D levels are monitored by the thyroid gland, which produces a hormone when levels are low, causing the skin to produce vit. D.
Vitamin D has two forms which are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D without a subscript refers to either D2 or D3 or both.Vitamin D3 is produced in the skin of vertebrates after exposure to ultraviolet B light.
No they do not. Land plants do not contain ergosterol; the precursor to vitamin D production. Vitamin D is synthesized in the skin of mammals through exposure of the skin to sunlight. Vitamin D can also be ingested in suppliment form or from foods including yeasts and from mushrooms.
The answer is vitamin D. In presence of ultraviolet rays cholesterol is converted to vitamin D in the skin. One hydrogen atom is attached to it in liver and second in kidney to form active form of vitamin D.
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
The Sun causes the synthesis of Vitamin D in the skin.
Vitamin D.
Vitamine E, B, C and D
Your skin is responsible for synthesis of Vitamin D.
Vitamin D
Vitamin D, of course.
No, vitamin D is not from jade stone. Vitamin D is an animal product. Good food sources of vitamin D are milk, eggs, fish, beef, etc. We can also produce vitamin D in our skin when it is exposed to ultraviolet radiation (usually from the sun).

Natural sunlight is an excellent source of vitamin d. The skin absorbs vitamin d from the sun's rays, but it is still essential to use sunblock to prevent skin damage.
Several vitamins help to maintain healthy skin, bones, and eyes. These include vitamin D, vitamin E, and vitamin A along with niacin.
Vitamin A and Vitamin E are the 2 i know of.
