Summary

Analyze the amount of change in blood serum Vitamin D levels in patients of 3 different dosing groups and how their levels change over a 3 month period of time.

Detailed description

Vitamin D has shown multiple health benefits specifically in regards to bone healing. To the investigators knowledge there are currently no protocols for Vitamin D supplementation in the Orthopedic community for patients recovering from fractures. The investigators study will monitor 3 different groups of volunteers taking various Vitamin D regimens and how participants blood serum 25(OH)D3 levels are effected throughout a 3 month period. The 3 groups will include: 1) 100,000 units D2 once on day one, 2) 100,000 units D2 taken once a week x 12 weeks, 3) 50,000 units D2 x 10 days, then 2000 units D3 taken daily for the remainder of the study period. There will be 15-20 volunteers randomly assigned to each of the 3 groups. The investigators will have each volunteer from the 3 groups have blood drawn a total of 4 times throughout the course of this study: prior to the study, week 2, week 6, and week 12. From these results the investigators will determine which protocol most effectively raises and maintains vitamin D levels in the volunteers through this 3 month period. The investigators will also use this data to determine which protocol is not only most cost efficient but also easiest to follow by individuals. The investigators are hoping that this study may help finally develop a universal orthopedic protocol for vitamin D supplementation in patients recovering from fractures.
