UPDATE 8.1.15 : Unfortunately, I will be repeating testing for my vitamin d, because the test I was given in this vid was not extremely sensitive. It would only show if had an extreme vitamin d deficiency leading to osteoporosis or a parathyroid issue, which says a lot, but not enough. I will be repeating with a more accurate 25 OH vitamin d test.
Nevertheless, there is studies on tanning they have high vitamin d levels compared to non-tanners.

Tanning is associated with optimal vitamin D status (serum 25-hydroxyvitamin D concentration) and higher bone mineral density.
Just how wide spread is vitamin d deficiencies?
