Intervention - Vitamin D

Intervention = Give Vitamin D (or Mg, Omega-3, etc) to a portion of study participants and see what happens
Typically

  • Intervene with the group: one dose size, but sometimes intervene while varying the dose size
    • perhaps such that each individual exceeds the 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, especially if > 4,000 IU

Note - some interventions use loading doses to restore levels quickly (days or weeks instead of months)
Which also includes small single dose of vitamin D - say 100,000 IU
Not listed - Trials which clearly used too little vitamin D or too short of period
