Department of Health and Human Services October 8, 2009 – Federal Register Recent Federal Regulation Documents

The Food and Drug Administration (FDA) is announcing the availability of the guidance entitled ``Implementation of Medical Device Establishment Registration and Device Listing Requirements Established by the Food and Drug Administration Amendments Act of 2007.'' The purpose of this guidance is to explain recent changes in the device registration and listing program to owner/operators and official correspondents of device establishments and to help them fulfill these new requirements. The guidance also describes the information that owner/operators of device establishments must submit to register their establishments and list their devices electronically, using FDA Form No. 3673. Those owner/operators seeking a waiver from the electronic submission requirement must submit their requests in writing to FDA with a complete explanation of why their registration and listing information cannot reasonably be submitted electronically. This guidance document is immediately in effect, but it remains subject to comment in accordance with the agency's good guidance practices (GGPs).

Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol.
