What causes vitamin D production?

Answer 1

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.

Answer 2

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 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.

Answer 6

Exposure of the skin to sunlight triggers the production of vitamin D. Specifically, UVB radiation from the sun converts a compound in the skin called 7-dehydrocholesterol into vitamin D3, which is then further processed by the liver and kidneys into its active form.
