  • Written informed consent using a document that has been approved by the Institutional Review Board.
  • The participant has not taken ergocalciferol in the month prior to study initiation. If receiving cholecalciferol, the dose is \< 1000/day and has been stopped one month prior to Day 0 (On Study).
  • Participants agree NOT to take ergocalciferol or cholecalciferol (except for\<500 IU that contained in a daily multi-vitamin) for six months after receiving the one-time dose of ergocalciferol.

You may not qualify if:
