Vitamin D3 is made in the skin when 7-dehydrocholesterol reacts with UVB ultraviolet light at wavelengths between 270–300 nm, with peak synthesis occurring between 295–297 nm. These wavelengths are present in sunlight when the UV index is greater than 3 and also in the light emitted by the UV lamps in tanning beds.

Humans need between 10 and 60 minutes spent in the sun allows the body to create enough vitamin D3 for an entire day. However, the skin cannot produce D3 in sunlight that’s filtered through a window, or on cloudy days.
