Summary

This study tested whether daily gummies containing L-theanine and lion's mane mushroom extract could reduce stress, anxiety, and improve sleep in university students. 67 students aged 18-25 took either the gummies or no supplement for 8 weeks. The goal was to see if this natural combination supports mental well-being during stressful university life.
