UV Lamp
Lamps which are designed to release UV-B radiation might also help boost the levels of vitamin D in your body. When the skin is directly exposed to these devices, it will start the synthesis of vitamin D. In general, UV lamps try to mimic the mechanism of the sun and would be particularly useful when your exposure to sunlight is limited due to time indoors or geographical locations. However, keep in mind that these lamps tend to be expensive. Also, safety is an essential concern since too much exposure would burn the skin. Ideally, you should not use UV lamps for more than 20 minutes per time. [9]
