\n"Vitamin D and Diseases of Aging" by Richard Jacobson
\nI\'m sorry the slides to this recent presentation aren\'t available as yet.
\n
\nPlenty of articles here to go at.
\nVitamin D wiki index
\n
\nDo bear in mind that there are benefits from UV exposure that are not related to Vitamin D3 and there are benefits to bright light exposure that are related to MELATONIN which is similarly pleiotropic. (multifunctional) So anyone who suggests that the problem is entirely solved by supplementing with D3 is being overly simplistic and anyone who thinks food sources alone can provide sufficient D3 is also equally misguided.
\n
\nMercola has been chuntering on about Vitamin D3 almost as long as I have and is a pretty good source of the basic information.
\nI don\'t think it\'s wise to think of any natural substance in isolation. Vitamin D needs it\'s cofactors to work naturally so magnesium, vitamin A, etc have to be considered as well.\r\n

\r\n \r\n Ted do you make a point to be out in the sun every day? \r\n

\r\n \r\n Remember I live in the UK in a region noted for it\'s BRACING winds. So given the wind chill factor and the general lack of sunshine I am only able to get into natural sunshine when conditions permit.
\r\n
\r\nI do have a uvb rich sunbed which I use regularly which I use to supplement my regular 5000iu/daily Vitamin D3 supplement.
\r\nThere is more to regular non burning UV exposure than just vitamin D3.
\r\nModulation of the immune system by UV radiation: more than just the effects of vitamin D
\r\n
\r\nI think people need to prepare their skin for UV exposure
\r\nSee previous thread and Healthy Fellows article on topic and appreciate that keeping your skin hardened to UV by regular SHORT sessions during the winter + keeping Vit d, omega 3, antioxidant levels higher than average but normal for outdoor living humans enables you to safely, without burning, get regular sun exposure.
\r\n
\r\nMy skin doesn\'t burn easily now, it used to, but the last few years I get as much sun as is available and haven\'t burn\'t.\r\n
