Summary
The purpose of this study is to evaluate vitamin D (VD) deficiency in the population of Chilean Antarctica and evaluate the efficacy and safety of VD supplementation to decrease VD deficiency and favorably influence biomarkers for bone, cardiovascular, and immune health risk in the inhabitants of Chilean Antarctica.
Detailed description
The present study consists of an initial cross-sectional evaluation of VD status and specific health biomarkers in inhabitants of Chilean Antarctica, followed by a randomized controlled trial evaluating two acceptable approaches of vitamin D supplementation (cholecalciferol 600 IU daily vs. 25000 IU weekly) in Antarctic inhabitants.
