Science is at the heart of everything we do here at Proper, starting with the sourcing of our raw ingredients at dosages clinically proven to support sleep. And while that provided a solid, evidence-backed foundation for us to develop our sleep supplements, it was really just the beginning.
Because once the supplements were developed, we then set out to determine the efficacy of the blends with respect to improved sleep quality.
The study was developed in partnership with Eileen Leary, PhD, RPSGT, who brings with her over 20 years of research and data analysis experience. She began her career as a sleep technologist before transitioning to data science to improve the quality of life for people with sleep problems by developing new diagnostic tools. She has both an MS and PhD in Epidemiology and Clinical Research from Stanford University and is currently focused on real-world evidence research to better understand how sleep medications affect those with sleep problems.
Included in the study were 29 adults, both male and female, between the ages of 29 and 54. All experienced sleep difficulties as measured by the Insomnia Severity Index.
The study was:
- Randomized: participants randomly assigned to separate groups (treatment vs placebo)
- Double blind: neither the researchers nor the participants know who is receiving the intervention treatment vs the placebo until the conclusion of the trial
- Placebo-controlled: there are two (or more) groups comparing an intervention treatment to a control (placebo)
The goal, over the 3-week study, was to evaluate the efficacy and tolerability of Proper in adults with issues either initiating or maintaining sleep.
Via the Insomnia Sleep Index, PROMIS questionnaire, as well as sleep diaries.
Those taking Proper showed significant improvement in:
- Sleep quality
- Total sleep time
- Daytime energy
- Satisfaction with sleep
By point of comparison, the placebo group did not show statistically significant changes across the key efficacy measures.
