I have been curious to know more about Vitamin D and have found that people take utmost care to have the proper intake of vitamin D. I came across one nice article about Vitamin D and you can find it interesting too. <a href="http://bocawellness.wordpress.com/2011/05/31/some-surprising-new-information-about-vitamin-d/" rel="nofollow">Boca Wellness and Nutrition</a> Good insight by the doctor.

Henderson Wed, 17 Feb 2010 09:16:11 +0000 http://www.proteinpower.com/drmike/?p=3427#comment-242993 I checked, and carotenoids do block UVA as well as UVB (in fact carotenoid sunscreens - the ubiquitous colourless carotene precursors phytoene and phytofluene - are being developed specifically to block UVA). One thing about carotenoids is that, in plants, they are used to catch photon energy and conduct it across the chloroplast; they don't just quench the solar energy, but pass it on quickly and safely to where it gets used in photosynthesis. If this applied to humans, carotenoids might actually facilitate Vit d conversion - but that's a very big if! On the other hand, if lipid-soluble antioxidants are very slightly decreasing vit d conversion in those people who are already very vit d deficient, it might explain the lack of expected benefit in large epidemiological studies - especially those from high northern latitudes, or in hospitalised populations.
