First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking L-tyrosine, a natural supplement, can help lower stress in adults having outpatient hernia surgery. About 150 participants will receive either L-tyrosine or a placebo before surgery, and their anxiety levels will be measured. The goal is to find a safer way to manage surgical stress without the side effects of common anxiety medications.
