I find the title of this article to be a bit disturbing.
Vitamin D is a fat based hormone. Hint it is modified fat
(cholesterol) produced normally by skin cells and UVB sunrays.
I find this interesting:

Ultraviolet (UV) Exposure Is Not the Answer
Our bodies manufacture vitamin D when the sun's ultraviolet B (UVB)
rays interact with 7-dehydrocholesterol (7-DHC) present in the skin.
"However, we can produce only a limited amount of vitamin D from UVB.
A few minutes at midday are sufficient for many Caucasians," says Roy
Geronemus, MD, clinical professor of dermatology at New York
University Medical Center and director of the Skin/Laser Division at
the New York Eye & Ear Infirmary. "After reaching the production
limit, further exposure actually destroys the vitamin, decreasing
vitamin D levels."
