Is this trial a fit for you?

Likely a good fit

Adults aged 35–65 who are generally healthy, have a BMI between 18.5 and 29.9, report trouble falling or staying asleep with a RU-SATED score ≤7, are willing to stop other sleep supplements/OTC sleep aids, and reside in the United States.

Probably not a fit

People with diagnosed or uncontrolled chronic sleep disorders, uncontrolled chronic medical conditions, those outside the age or BMI ranges, or those unwilling to discontinue other sleep treatments are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, double-blind, placebo-controlled trial enrolling 140 generally healthy adults with sub-clinical sleep problems (RU-SATED score ≤7). Participants are randomized to receive either the novel powdered supplement or a matching placebo and must stop other sleep-focused supplements or over-the-counter sleep aids for the study duration. Eligible participants are aged 35–65 with BMI 18.5–29.9 and must agree to limits on evening alcohol and caffeine intake. The single-site study is conducted at Citruslabs in Santa Monica, California, and compares sleep-related outcomes between groups.

Why it matters

Potential benefit: If successful, the supplement could provide a safe, non-prescription option to improve sleep onset, maintenance, and overall sleep quality for adults with mild sleep disturbances.

How similar studies have gone: Some individual nutritional supplements (for example, melatonin or magnesium) have shown modest, mixed benefits for sleep, but the specific supplement being tested here appears novel and not previously proven in large randomized trials.
