Effect of Fish Oil Supplementation on the Voice of Female Professional Voice Users (PVU)

The design of the study allows us to test if there are differences in a battery of voice assessments (Aim 1) and biomarkers from vocal fold secretions (Aim 2) over time (within-subjects factor with 6 levels: 3 pre-intervention and 3 post-intervention) secondary to intervention with an omega-3 polyunsaturated fatty acid or a placebo (between-subjects factor with 2 levels). Cis-gender females (N = 68) over the age of 18 and pre-menopausal from the McLennan County, TX area will serve as participants in this study. This sample size is the minimum needed to show effect for one voice outcome measures, phonation threshold pressure, accounting for a 20% attrition rate. All human subject research will be performed on Baylor University's campus.
