Synthesis of pre-vitamin D<sub>3</sub> in the skin involves [[UVB radiation]], which effectively penetrates only the epidermal layers of skin. 7-Dehydrocholesterol absorbs UV light most effectively at [[wavelength]]s between 295 and 300 [[nanometer|nm]] and, thus, the production of vitamin D<sub>3</sub> will occur primarily at those wavelengths. The two most important factors that govern the generation of pre-vitamin D<sub>3</sub> are the quantity (intensity) and quality (appropriate wavelength) of the UVB irradiation reaching the 7-dehydrocholesterol deep in the stratum basale and stratum spinosum. Light-emitting diodes ([[LED]]s) can be used to produce the radiation.</div>FuzzyBot
