Analysis of the Effects of Known Sleep-Support Supplements in Relation to Life Habits, Sleep Conditions, and Sleep Problems
Nutrients (2023) · Rct · n=160
All the tested supplements were found to ameliorate sleep problems significantly (Analysis 1).
Based on meta-analysis of 437 participants showing improvements in attention, processing speed, and working memory. However, one large RCT (n=101) found no significant between-group differences. Effects may take 8-12 weeks to manifest. Standardized extracts (Bacognize, Synapsa) may have better bioavailability than generic forms.
Meta-analysis (n=897) and multiple RCTs support sleep benefits. Studies often used L-theanine in combination with other compounds, limiting pure L-theanine effect attribution. Effects include reduced sleep onset latency and improved subjective sleep quality.
