Vitamin D is not found IN the skin...it is produced endogenously (from within the body) when ultraviolet rays from sunlight strike the skin and trigger Vitamin D "synthesis" (or production). Vitamin D that you get from sun exposure, food, and supplements is biologically inert (non-working) and must go through two things in the body for it to become active. This process starts in the liver, converting the vitamin D to calcidiol. Then, the kidney takes over and turns the Calcidiol, into Calcitriol. We need Vitamin D so that we can absorb "calcium" to prevent bone loss. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Together with calcium, vitamin D also helps protect older adults from osteoporosis.
Vitamin D has other roles in human health, including modulation of neuromuscular and immune function and reduction of inflammation.

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.
Your skin is responsible for synthesis of Vitamin D.
Vitamin D
Vitamin D, of course.
Vitamin D is formed in your skin when the skin is exposed to UV
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.
Vitamin A and Vitamin E are the 2 i know of.
Both vitamin A and D!
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.
