Brief Summary
Melatonin is a hormone naturally found in our body that increases in our blood at night and controls how we sleep. Melatonin can also be taken as a pill and numerous clinical trials have documented improved sleep quality following melatonin supplementation before bed. However, it is not known whether such supplements actually increase blood melatonin above normal levels, particularly at night. The aims of this study are to investigate whether a novel melatonin supplement (Ritual Sleep BioSeriesTM Melatonin) can increase blood melatonin in human participants at night, and to determine if taking the supplement before bed for two-weeks can improve sleep quality.
