Summary
The investigators hypothesize that native vitamin D will have more variability in 25(OH)D dose response when compared to a given equipotent dose of 25-hydroxyvitamin D3. This will be a single blind, active control, pharmacokinetic study of 625 μg 25(OH)D given orally or 2500 μg native vitamin D given orally.
Detailed description
Single blind, active control, pharmacokinetic study of 625 μg 25(OH)D given orally or 2500 μg native vitamin D given orally.
