Study Description

Brief Summary:

The investigators predict that a powder pill form of vitamin D will be more effectively absorbed than an oil form of vitamin D in people diagnosed with Cystic Fibrosis.

Condition or disease	Intervention/treatment	Phase
Cystic Fibrosis	Dietary Supplement: Vitamin D Powder Dietary Supplement: Vitamin D Oil	Phase 4

Detailed Description:

The purpose of this study is to see how well two different forms of vitamin D work in Cystic Fibrosis (CF). Patients with Cystic Fibrosis have a hard time absorbing certain foods and often have low vitamin D levels. Studies show that vitamin D may help fight infections common in Cystic Fibrosis. The investigators would like to see if a powder pill form of vitamin D will work better than a pill mixed with oil. Each person will randomly receive either a powder pill or an oil based pill. Blood will be tested while during a 3-4 day hospital stay. The investigators plan to enroll no more than 24 patients with CF from Emory University Hospital for this study.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: 100,000 IU D-50 powder Vitamin 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	Dietary Supplement: Vitamin D Powder 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 Other Name: D3-50 Cholecalciferol
Active Comparator: 100,000 IU Maximum D3 in oil Vitamin D oil vs powder. One Dose of 100,000 IU vitamin D oil format administered. Absorption rate monitored over 72 hour period	Dietary Supplement: Vitamin D Oil Patients will be randomly assigned to an oil based 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 Other Name: Maximum D3

Outcome Measures

Primary Outcome Measures :

Rate of Absorption of vitamin D3 to blood [ Time Frame: 72 hours ]
rates of absorption of D3 will be compared for either an oil based or powder form pill OVER 72 HOURS.
