But vitamin D is unique for a few reasons.<\/p>\n<p>First, it\u2019s not really a \u2018vitamin.\u2019 Vitamin D researchers recognize that the production of vitamin D in the body is really the pathway to the production of the hormone called calcitriol \u2013 an active form of vitamin D. That hormone is one of the most powerful hormones in the body.<\/p>\n<p>Second, it\u2019s most natural and abundant source is not from food \u2014 a fact that Sun Scare proponents seem willing to distort. By natural design, sunlight exposure to the skin makes most of our vitamin D.<\/p>\n<p>According to the University of California-Riverside, \u201cHess and Weinstock confirmed the dictum that \u2018light equals vitamin D\u2019. They excised a small portion of skin, irradiated it with ultraviolet light, and then fed it to groups of rachitic rats. The skin that had been irradiated provided an absolute protection against rickets, whereas the unirradiated skin provided no protection whatsoever; clearly, these animals were able to produce by uv irradiation adequate quantities of &#8220;the fat-soluble vitamin&#8221;, suggesting that it was not an essential dietary trace constituent.\u201d<\/p>\n<p>To read UC-Riverside\u2019s account of this moment in vitamin D research history <a href=\"http:\/\/vitamind.ucr.edu\/about\/\" target=\"_blank\">click here<\/a>.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/smarttan.com\/news\/wp-content\/uploads\/2012\/09\/SmartTan_member-content.png\"><img decoding=\"async\" class=\"aligncenter size-full wp-image-10125\" title=\"SmartTan_member content\" src=\"https:\/\/smarttan.com\/news\/wp-content\/uploads\/2012\/09\/SmartTan_member-content.png\" alt=\"\" width=\"350\" height=\"126\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cLight equals D.\u201d &#8211; early vitamin D pioneer Alfred Fabian Hess, in 1923.
