All mammals can naturally synthesise vitamin D from cholesterol via sunlight. All ingested forms of vitamin D are actually additives or supplementary; there is no vitamin D in milk or other staple foods (it is added, and therefore not natural). Strictly speaking, vitamin D is not a vitamin at all, as a vitamin is, by definition, a chemical compound that cannot be synthesised by an organism.
Vitamin D
They get all that they need from their diet, heavy on types of fatty fish products that are naturally rich in vitamin D.
Vitamin D. It is produced in small quantities when the skin is exposed to natural sunlight and UV radiation.
Vitamin D would not be synthesized in a person confined to a dark cell for a long time. Vitamin D is primarily synthesized in the skin in response to sunlight exposure. Without access to sunlight, the body would not be able to produce vitamin D naturally.
Yes! Sunlight exposure is how our bodies naturally create vitamin D.
The sun does not provide vitamins, but will help the production of vitamin D from the Ultraviolet rays from the sun. So if you are looking to increase your intake of vitamin D, this is not a beneficial way to do so because you are exposing yourself to dangerous UV rays that lead to skin cancer. You are better off taking a daily multi-vitamin. -Chanel Peacock, MA-

Mushrooms provide vitamin D, if exposed to just 5 minutes of UV light after being harvested; this is one of a few natural sources of vitamin D for vegans. Very few foods are naturally rich in vitamin D, and most vitamin D intake is in the form of fortified products including milk, soy milk and cereal grains. Currently, there are some companies selling mushrooms that have been exposed to UV light and contain high levels of Vitamin D.
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
Few foods contain Vitamin D. The best source is sunlight. Foods that do contain Vitamin D are: cod liver oil, oily fish (trout, salmon, mackerel, tuna, tilapia, etc.), tofu, and caviar (fish eggs).
