Objective Sleep Quality
Ingesting glycine before sleep significantly improved objective sleep quality as measured by a multi-measurement technique called polysomnography.3
Participants forced to sleep 25% less than usual for three nights but given glycine before bed showed 50% reduction in subjective fatigue as well as improved 'fatigue,' 'peppiness' and 'clear headedness'.4
