Can sunbeds stimulate the production of vitamin D?
Short answer: YES
Long answer: Yes because, in fact, ALMOST ALL of the studies showing the stimulation of vitamin D in the skin by exposure to the vitamin D-effective wavelengths of ultraviolet light have been done in sunbeds!
DLS Note: The only study I know of that measured the effect of sunlight on the production of vitamin D was a study of submariners who were underwater for 180 days (and, therefore, had very low vitamin D levels) and then had shore leave for seven days in Hawaii. All of the others (including the first controlled study by Matsuoka, et al) USED SUNBEDS.

Another important question addressed in the video is, can sunbeds be used to make vitamin D, especially in winter? "Sunbeds of course can be used to make vitamin D. It has been one of the ways that we have measured the amount of vitamin D that the skin has the capacity to make," stated Dr. Reinhold Vieth, a professor at the University of Toronto in the Department of Laboratory Medicine and Pathobiology.

Dr. Reinhold Vieth from Mount Sinai Hospital in Toronto said this about sunlight and tanning beds in a court affidavit; sunbeds and summer sunshine are effective means by which to increase our serum 25(OH)D levels. The advantage of a tanning bed is that exposure to UV light can be controlled more precisely than casual sun exposure and thus can be safer than advising the public to guess at their own sun exposure from sunlight.
