Which is better to prevent cancer, sunlight or vitamin D?

I like it when a paper begins by assuming sunlight and vitamin D both help prevent internal cancers, not just vitamin D. Recently, that is exactly what Dr. Han van der Rhee and colleagues from the Netherlands did in asking an important question, which is better to prevent cancer, sunlight or vitamin D?

    How about using “narrow UVB” lamps by Solarc? http://www.solarcsystems.com/vitamin-d-phototherapy-faq.html

    SolRx 500-series seems to be ideal: http://www.solarcsystems.com/narrowband_uvb.html

    What do you think?

      omegagx, I believe the owner of Solarc is a Council member. Perhaps he’ll join in the conversation?

      The UVB sunbeds are low-pressure and emit some UVB, similar to the sun. So as far as our “use low-pressure sunbeds that have some UVB”, they fit our recommendation.

  2. I purchased and installed a much lower cost UVB lamp next to my bathroom mirror.

    I measured its output with a UVB meter calibrated in units of vitamin D.

    $195 lamp provides at least 1000 IU per 5 minutes at a distance of 2 feet.

    The page also has information on another supplier – Sperti

    “At least” 1000 IU. It may produce more than 1000 IU/5 minutes since it is not hindered by having any UVA.
