Light skin exposed to tropical sun will produce more vitamin D than dark skin, because the UV light is less filtered by the pigment melanin. That is why a light skinned person only needs a few minutes of tropical sun each day to get enough Vitamin D. Any more than that is only increasing the risk of skin cancer. The skin darkens to try to protect you from UV radiation.
Vitamin D. The body produces vitamin D when sunlight (ultraviolet light) strikes the skin.
There is no vitamin that is absorbed through uv rays , but when uv light falls on skin , it produces vitamin D in skin by a photochemical reaction .
Natural light produces vitamins D and C. Vitamin D in light is known to improve brain functioning in persons with down syndrome.
you will be deficient in certain vitamins that your body produces through contact with light. but, you can get those vitamins from food or vitamin suppliments. so, theoretically no, you don't need light.
Human skin produces Vitamin D in presence of sun light but not the other parts of body.
Vitamin C is sensitive to light, air and heat.
Vitamin A, Vitamin B12, Vitamin D, Folic Acid, Vitamin K, Vitamin E, Pyridoxine, Riboflavin
Vitamin C is a vitamin that is easily destroyed by light and irradiation. It is sensitive to heat and light exposure, meaning that storage and cooking methods can affect its concentration in foods. To preserve the vitamin C content, it is best to store foods rich in vitamin C in cool, dark places and avoid prolonged exposure to light.
Vitamin D but it requires ultraviolet light.
Vitamin A is a vitamin that is needed by the retina of the eye in the form of a specific metabolite, the light-absorbing molecule retinal, that is necessary for both low-light and color vision.
Pigment that protects from the ultraviolet light is called melanin. This is science.
ultra violet destroys gradually the vitamin c
