Effects of L-Theanine and Hericium Erinaceus-Enriched Gummies on Psychological, Cognitive, and Sleep Quality in University Students: An 8-Week Randomized Controlled Trial (THEA-HEAL Trial)
Effects of L-Theanine and Hericium Erinaceus-Enriched Gummies on Psychological, Cognitive, and Sleep Quality in University Students: An 8-Week Randomized Controlled Trial (THEA-HEAL Trial)
The THEA-HEAL Trial is an 8-week randomized controlled study investigating the effects of a daily gummy supplement containing L-theanine and Hericium erinaceus (Lion's mane mushroom) extract on stress, anxiety, cognitive performance, and sleep quality in university students in Malaysia. University life can be a stressful period associated with increased psychological distress, sleep problems, and difficulty concentrating.
In this study, eligible participants aged 18-25 years were randomly assigned to either receive the active gummy supplement or no supplementation. The intervention group consumed gummies twice daily, providing a total daily dose of 180 mg L-theanine and 300 mg H. erinaceus extract.
The main purpose of the study is to determine whether this nutraceutical combination can help reduce stress and anxiety and improve cognitive function and sleep quality compared with no supplementation. Additional outcomes include physical activity levels and dietary intake. Findings from this study may provide evidence on the potential role of functional food-based supplements in supporting mental well-being and cognitive health in young adults.
