Will SAD lights provide UV light that would increase vitamin D levels? I'm Looking to find a solution for in home lights that may work to increase vitamin d levels where I live in a northern climate that has much less sun during the winter.

    No, SAD lights do not contain the same wave length. You would have to get something from Sperti or the like. There is a link at the top of the page, in the “revolving” advertisements. Time in front of it would depend on your skin color meaning fair, medium, dark etc. You can also do a tanning salon but then you have to make sure that the actual machine includes what they would call “natural light spectrum” and NOT just UVA rays. Also you have to expose enough skin. Just arms and face are NOT enough.
