Primary Outcome Measures:
  • The Vitamin D levels of the 100 subjects will be statistically analyzed as the primary variable and correlated with the rest of the variables via ANOVA and meta-analysis [ Time Frame: Initial clinic visit ] [ Designated as safety issue: No ]
    This research study consists of a single clinic visit. After study subjects have completed the informed consent process and are determined to meet study eligibility, a blood sample will be collected. Values from these lab samples will be compared between study arms.
