Overview Kidney and vitamin D

  • FACT: Kidney is the primary way to activate vitamin D
  • FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
  • FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
  • FACT: There are many on-going intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
  • FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
  • FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
  • Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
      Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
    Calcitriol - which bypasses the need for the kidney to activate vitamin D
      Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications
        Update: Pre-cursor of active vitamin D made from plants is better than calcitriol – Sept 2012
