Summary

This study tests whether L-theanine, a natural substance found in green tea, can help cancer survivors feel more relaxed and improve their mood. About 50 adults who have finished cancer treatment and are under surveillance will take L-theanine and report their stress and anxiety levels. The goal is to find the best dose and see if it's a practical way to support emotional well-being after cancer.
