The Sun gives off light.
The body uses light to convert 7-dehydrocholesterol into pre-vitamin D3. Pre-vitamin D3 forms in to cholecalciferol, vitamin D3. Vitamin D3 is brought to the liver were it forms 25-hydroxyvitamin D. Finally, it is brought to the kidney to form 1,25-dihydroxyvitamin D, the active form of vitamin D.
Vitamin D is made from a series of Organic and toxic - free sources, some scientists say vitamin D is also made from un-rotten solids such as a banana peel. To make vitamin D you combine the ingredients in which you are trying to process and form it into different shapes & sizes. E.g. Tablet pill.
Vitamin D is produced in the skin by the effect of the sunrays and the UVB rays of the sun. Food sources like milk, cheese, vegetables also help in vitamin D production. This vitamin is important for bones and teeth.
Vitamin D can be made in our bodies- in the skin to be exact, but only if sunlight is available to carry out the synthesis. vitamin D or calciferol, is a fatsoluble vitamin. It exists in several forms, each with a different biological activity.
Vitamin D3 (cholecalciferol) is made by the body and is found in some foods.
Vitamin D2 (ergocalciferol) is the form most often added to milk and other foods, and the form most often found in nutrtion supplements.
In vivo (in living beings), in humans, ultraviolet light reacting within skin cell.
the keratinocytes in the epidermal, when it exposed to UV light produce vitamin D
Production of melanin in the skin decreases; so does production of vitamin D.
Ultraviolet A (long wavelength) initiates production of vitamin D and melanin (tanning). Ultraviolet B (short wavelength) damages the skin causing sunburns and in some cases cancers.
Vitamin d
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.
Vitamin D
The Sun causes the synthesis of Vitamin D in the skin.
vitamin d
"enables" in what way? If you mean production of vitamin D and causes tanning it is UV.
Ultraviolet
yes it does
the keratinocytes in the epidermal, when it exposed to UV light produce vitamin D
No, it does not produce vitamin D.
Production of melanin in the skin decreases; so does production of vitamin D.
Ultraviolet A (long wavelength) initiates production of vitamin D and melanin (tanning). Ultraviolet B (short wavelength) damages the skin causing sunburns and in some cases cancers.
