    You don't need full spectrum lightning. Only UVB. The lightwaves in UVB varies between 290nm and 320nm (nanometer)

  • I'm curious to know if full spectrum lighting enables the body to produce vitamin D.

  • The risk of skin Cancer comes mainly from toxins in your body and sunscreens which do turn toxic in the body.

    The amount of time Dr Mercola mentioned for sun exposure is a general amount of time so people actually have a concept of how much time so they don't get a fraction also so they don't go and burn themselves.

    For Vitamin D3 to absorb its 48hours plus if you're using soap to clean the area you got sun your eliminating the D3 effect, washing with water and the needed areas with soap is best

  • Dr Mercola knows perfectly well that the amount of vitamin D you get from the sun vary from person to person facts are it takes 48hours for the vitamin D3 to form in the human body so if you tested a surfer and he wasn't in the sun for a couple of days he won't likely have sufficient D3 in his system plus....

  • So it is pretty easy to understand that certain entities do not want you to have access to the proper information so you can benefit!

  • Grassrootshealth D Action offer postal 25(OH)D testing .

    No need to ask your doctor.

    Urban atmospheric pollution main reason for poor response to sun.

    Some foods induce Vitamin D insufficiency.

    2000iu/d too low

    "Startling Findings About Vitamin D Levels in Life Extension® Members" shows 5000iu/daily = average 42ng/ml.

    Around 60ng/ml human breast milk is vitamin d replete. At latitude 32N 6400iu/d/d3 required further north more needed.

  • very important information
