Brief Summary
This study aims to investigate the effect of a 4-week dietary intervention of 300mg encapsulated aqueous lemon balm extract on measures of sleep quality, mood and well-being, alongside relevant biomarkers of circadian rhythms in healthy adults aged 18-40 years with mild sleep problems (PSQI entry of 5 and above). Three visits to the university alongside completing some home tests involving self-test stool, saliva and mood tests and wearing an wrist-secured actiwatch over 4-weeks whilst recording a daily sleep diary will be monitored to estimate sleep changes. Mood ratings, stool and saliva biomarkers will serve as a proxy to sleep improvement.

Outcome Measures
Primary Outcomes (1)
Pittsburgh Sleep Quality Index (PSQI)
A validated measure of sleep assessing qualities and patterns within the last month of sleep habits in adults. Seven components of sleep (quality, latency, duration, efficiency, disturbance, use of sleep medication, daytime dysfunction) will be summed to achieve a global PSQI score ranging from 0 to 21 points, where scores above 5 indicates sleep problems.
