What the studies found
Study 01 · 2019
Falling asleep and sleep disturbances
Malaysian Journal of Public Health Medicine
At week four, the supplement group had better questionnaire scores for time to fall asleep and sleep disturbances than the placebo group.
The overall sleep score improved within the supplement group. The difference between groups was statistically inconclusive.
How the 2019 study worked
In this four-week trial, 70 adults were randomly assigned to take the supplement or a placebo. The reported results included 48 adults. Participants filled in a standard sleep questionnaire each week.
LiveLife Biosciences AG funded the study.
Study 02 · 2022
Time asleep and sleep efficiency
Nutrients
Participants reported sleeping longer and spending a greater share of their time in bed asleep during the supplement period.
Both findings held across the two analyses.
How the 2022 study worked
The trial included 39 working adults with poor sleep quality. The same participants took the supplement and a placebo for four weeks each, in random order, with a one-week break between periods. Researchers also recorded brain activity while participants were awake.
The UTAR Research Fund and LiveLife Biosciences AG funded the study.
Putting the findings in context. Both trials were short, involved small groups of adults and used self-reported sleep measures. Individual experiences can vary.
