Notes for this study:
In a blinded and controlled study using 3g glycine taken an hour before bed, supplementation appears to promote sleep quality associated with reduced sleep latency and reduced time to reach slow wave sleep (no influence on REM sleep and overall sleep architecture) which resulted in improved daytime fatigue and cognition scores. The subjects were those who reported dissatisfaction with their sleep.
