Vitamin D Inadequacy in Rural Populations, Evaluation of Correction by Food Supplementation

Vitamin D Deficiency Clinical Trial

Official title:
Vitamin D Inadequacy: Documentation in Rural Populations and Evaluation of Correction by Food Supplementation (Phase III; Manitowoc Prevalence Study)

Clinical Trial Summary

The purpose of the research is to describe vitamin D levels and bone status in a rural Wisconsin population. It is probable that individuals of varying age and ethnicity require different amounts of D to achieve optimal status. These likely scenarios will be explored in various populations. We hypothesize that the increase in serum 25(OH)D resulting from daily D3 ingestion is less pronounced with advancing age and different in Native than Caucasian Americans. In addition, the women in the middle age group, between the ages of 55 and 65, will have ultrasound tests completed to assess the impact of the Vitamin D supplementation on cardiovascular health.
