Outcome Measures
Primary Outcomes (1)
Rate of Absorption of vitamin D3 to blood
rates of absorption of D3 will be compared for either an oil based or powder form pill OVER 72 HOURS.
72 hours
Study Arms (2)
100,000 IU D-50 powder
ACTIVE COMPARATORVitamin D oil vs powder. 100,000 IU powder form of vitamin D, assessment of D3 absorption. One Dose of vitamin D powder format administered. Absorption rate monitored over 72 hour period
100,000 IU Maximum D3 in oil
ACTIVE COMPARATORVitamin D oil vs powder. One Dose of 100,000 IU vitamin D oil format administered. Absorption rate monitored over 72 hour period
Interventions
Patients will be randomly assigned to a powder supplement of 100,000 IU vitamin D3. Randomization will be in blocks of 4 (meaning for every 4 subjects there will be 2 vitamin D and 2 placebo treated patients). Blood will be drawn by IV catheter at baseline, 2, 4, 8, 12, 24, 48, and 72 hours after vitamin D3 dosing
