Intervention - Vitamin D

Intervention = Give Vitamin D to a portion of study participants and see what happens

  • Intervene with the group" the same IU, but sometimes intervene and vary the IU
    such that each individual exceeds a desired blood level (say 40 ng)
  • Group size: 50 to 500 people, but can be ~ 100,000 individuals (Turkey- Rickets)
  • Vitamin D3, but sometimes an activated form (Calcidiol, or Calcitriol)
  • Disease treatment, but sometimes disease prevention
  • Just Vitamin D (monotherapy), even though cofactors are very important
