How does the skin make vitamin D and what limits its production?
The wants for d vitamin differ based on the age range. You can find smaller probabilities to develop Vitamin D toxicity just by obtaining it out of food as well as the sun however it can cause the quantities of calcium mineral in your body to improve considerably. This disease can easily cause some critical problems with the bone fragments, heart or kidneys.
Sun or UV light is the fuel that permits to body to manufacture vitamin D. But the amount of vitamin D formed in a given period of exposure depends on the color of your skin — that is, how rich the skin is in melanin. Melanin absorbs UV radiation therefore it diminishes the production of vitamin D. The darker a person’s skin, the longer he or she has to be in sun or exposed to UVB radiation to form a significant amount of vitamin D. Like melanin, sunscreen also absorbs UV radiation and therefore greatly diminishes vitamin D production by the skin. For example, a sunscreen with a PDF of 8 diminishes ability to produce vitamin D by 95%. In addition, winter sunlight in the northern latitudes (New York City, Boston, and San Francisco) does not have enough UVB radiation to produce vitamin D in the skin. This is the reason most Americans are at risk for vitamin D deficiency, especially in the winter. A national study showed that 42% of African-American women ages 15 to 49 were deficient in

Therefore it diminishes the production of vitamin D. The darker a person’s skin, the longer he or she has to be in the sun or exposed to UVB radiation to form a significant amount of vitamin D (2). Like melanin, sunscreen also absorbs UV radiation and therefore greatly diminishes the skin’s vitamin D production. For example, sunscreen with a PDF of 8 diminishes a person’s ability to produce vitamin D by 95%. In addition, winter sunlight in the northern latitudes (Manitoba) does not have enough UVB radiation to produce vitamin D in the skin. This is why many Americans are at risk for vitamin D deficiency, especially in the winter (3).
