Dear Sir: I have recently come across several news article all citing the same study from the The Journal of the American Osteopathic Association stating that using sun screen may cause vitamin D deficiency (reduction of vitamin D3 production by 99 percent!) Could you please provide you expert opinion on that topic? I am vitamin D deficient but I am also afraid of skin caner risk without sun screen protection. Thank you so much~

    From http://ajcn.nutrition.org/content/80/6/1678S “Sunscreens work by absorbing UVB radiation and some UVA (321–400 nm) radiation before it enters the skin.” “Therefore, it is not surprising that a sunscreen with a sun protection factor (SPF) of 8 reduces the capacity of the skin to produce vitamin D3 by >95% (Figure 4⇑) (20); properly used sunscreen with a SPF of 15 reduces the capacity by >98%.”
    In 2012 the Vitamin D Council said the following:
    You cannot adequately produce vitamin D AND protect your skin at the same time.
    You should separate time for vitamin D production and time for skin protection.
    The Vitamin D Council recommends full body exposure before you turn pink. Then, cover up with clothes or shade. If you must use sunscreen instead of clothing/shade, apply sunscreen generously.
    Now you can worry about skin cancer if you want to. The following, though, is fact. At Vitamin D levels below 40ng/ml (100nmol/l) your chance for (internal) cancer and autoimmune disease rises dramatically!
    If you are deficient, then why do you not take a Vitamin D supplement? We recommend no less than 5000iu a day.
