Outcome Measures
Primary Outcomes (1)
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
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.
