The purpose of this study is to observe changes in iron status and vitamin D status during a 12-24 week supervised training program, specifically males and females between the ages of 30 and 50 years old.
Study subjects will be participants in a triathlon training program through the Avera Sports Institute in Sioux Falls, SD. This clinical study will examine changes in iron and vitamin D levels. Blood specimens will be collected at baseline and again after 3 and 6 months of participating in the training program.
