JUST. THE DETAILS.
You deserve more than a promising headline. Here’s a closer look at published research on three ingredients listed in SLEEP—with the study details and limitations in the same place.
Compare with the SLEEP formula30 adults · 200 mg/day · 4 weeks
A small placebo-controlled trial found improvements in some self-reported sleep measures after L-theanine, including time taken to fall asleep and sleep disturbance.†
The trial used 200 mg of L-theanine per day. SLEEP lists 25 mg per gummy. A different dose and a different formula mean these results cannot be assumed for the finished gummy.
41 adults · Herbal tea · 1 week per treatment
Participants rated their sleep quality more highly during a week of passionflower tea than during a week of placebo tea. Sleep quality was one of six diary measures assessed.†
This was a short study of tea, not a gummy or the JUST. formula. Self-reported sleep quality does not establish a benefit for every aspect of sleep or for long-term use.
16 trials · 1,093 participants · Varied preparations
A review found a signal for improved subjective sleep quality in a subset of valerian trials, but most included studies had substantial methodological problems.†
Doses, preparations, and study lengths varied, and the authors found evidence of publication bias. The findings are not proof that a particular valerian product—or SLEEP—will deliver the same result.
KEEP THE WHOLE PICTURE.
SLEEP also lists reishi extract and lemon balm. This is a selected reading list, not a complete evidence review of every ingredient or of the finished formula. An ingredient’s presence alone doesn’t tell you how well a product will work for you.
Check the complete label and warnings before use. Ask your doctor or pharmacist about supplements if you take medication, have a health condition, or are pregnant or breastfeeding. Read the FDA’s guidance (opens in a new tab)
