A new wave of sleep
We did the heavy lifting,
so you don’t have to.
Paying for an overnight sleep study doesn’t make sense. That’s why we took matters into our own hands, and invested in a 6 week longitudinal study with 1200+ participants.
We were unsatisfied with existing sleep solutions, and you should be too. You deserve sleep products that will sustainably improve your sleep quality without negative long term side effects. We set out to find that, working with our team of Stanford and Harvard researchers to identify and rigorously study the best ingredients pulled across various fields including Naturopathic medicine, neuroscience, and Traditional Chinese Medicine.Study Design
Our team of researchers from Stanford and Harvard teamed up to design this study with clinical validity and academic rigor.
1204 participants across 35 Ingredients tested
We conducted a power analysis to determine the required sample size of 1204 participants across 35 ingredients, to guarantee statistical significance. These 1204 participants were randomly assigned to test groups, each receiving its own unique nightly combination of ingredients.
In addition to the test groups, we had a placebo control group and a melatonin control group. This gave us baseline data to compare our products against.
Neither the participants nor the researchers knew which participants were in which group in order to prevent bias.
Our study lasted a total of 6 weeks, with a week of baseline data, and 5 weeks of test data. This allowed us to evaluate the way in which certain products' efficacy changed over time with nightly use. Over the 6 week period, participants submitted sleep logs every morning. Additionally, participants submitted weekly logs to summarize their overall sleep each week.
Results / Analysis process
After gathering the data over the 6 week period, we then analyzed the results using regression analysis and ANOVA analysis to determine which specific combination of ingredients produced the most impact across a range of relevant sleep metrics.
What we found
