Trial to Evaluate the Efficacy of a Zinc, Selenium, and L-Tyrosine Supplement in the Prevention of Thyrotoxicosis in Subjects With r25191G/A SEPP1 Polymorphism

Overview

This randomized, double-blind, placebo-controlled trial evaluates the efficacy of a zinc, selenium, and L-tyrosine supplement in preventing thyrotoxicosis among adults aged 18-85 with elevated TPOAb levels and the r25191G/A SEPP1 polymorphism. The study excludes those with thyroid disease, pregnant/breastfeeding women, and individuals allergic to the supplement. Key endpoints include changes in thyroid antibodies and hormones over a 6-month period. With an estimated sample size of 150 participants per group, accounting for a 20% dropout rate, the trial seeks to demonstrate the supplement's potential in reducing thyrotoxicosis risk through a genetically-informed approach.
