Vitamin D is actually a type of hormone and produced by our skin with the help of ultraviolet light. When we are exposed to sunlight, the ultraviolet rays strikes the 7-dehydrocholesterol molecule that’s converted to provitamin D. This nutrient is produced by the UV-B wavelength, at about 282nm. At this wavelength, the ultraviolet rays don’t penetrate transparent surface well. So, we won’t get the full benefit if we are behind the window. Clothing is another thing that obstructs the UV-B from reaching our skin, so it is a good idea to wear the least clothes. Dark-skinned people block more ultraviolet ray, so they need to get exposed with sunlight longer to get the same benefit. Sunlight isn’t enough; we also need to eat good food
