Yawn combines the sleep-inducing effects of melatonin and L-Glycine, to help get the body and brain in recharge mode.
Clinical studies on melatonin demonstrated an overall 3% improvement in sleep efficiency.1
Magnesium is an essential dietary mineral, and the second most prevalent electrolyte in the human body
The glycinate form adds bioavailability of magnesium and additional glycine content6
Supplementing as magnesium glycinate increases the bioavailability of magnesium and provides additional glycine7
Hormone produced in the brain that promotes sleep and regulates circadian rhythm (sleep-wake cycle)19
Helps to normalise the sleep-wake cycle after travel across time zones22
Neuroprotective due to antioxidant and antiinflammatory properties23
HVMN Evidence Grading
Rooted in principles of science and engineering, we share full knowledge of HVMN products and their ingredients. Each products is systematically graded by the breadth of evidence available:
Theoretical effect or in vitro evidence
Animal model evidence of effects
Early human evidence of ingredient effects
High-quality human evidence of ingredient effects
Human study of product as sold
Improved Sleep Quality
Ingesting glycine before sleep significantly improved objective sleep quality3. When given glycine before bed, participants of a sleep study showed 50% reduction in subjective fatigue as well as improved "fatigue", "peppiness" and "clear headedness".11
