Product analysis
Sleep combines valerian, GABA and calming herbs that may help with winding down. Unspecified extract details make the size and consistency of that benefit uncertain.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality31
Valerian and passionflower have named markers, but those markers do not identify the exact extracts. Quality remains uncertain for the formula, including the unspecified hops and GABA forms.
Ingredient Transparency81
All ingredient amounts are listed, and valerian and passionflower have marker details. Hops and GABA lack stated forms, while the extract descriptions do not fully identify the preparations.
Value For Money50
The serving cost compares favorably for valerian, while GABA offers more limited value. Value for hops and passionflower remains uncertain, so the blend has a mixed value picture.
Customer Satisfaction80
Customer feedback is generally positive. A sizeable set of reviews supports that impression, without proving effectiveness or safety.
Product Focus72
The formula is more relevant to calming and winding down than to changing sleep timing. Possible stress and sleep benefits remain uncertain because findings vary by ingredient and extract.

Goals
Impact
Moderate effect
Valerian may help with winding down, with GABA adding a possible calming contribution; passionflower may contribute as well, but less is clear about this extract. The formula's potential is centered on calming rather than sleep timing.
Valerian is labeled as a root extract with a valerenic-acid marker, but its extraction details aren't specified; passionflower is flavonoid-standardized without a named preparation. Hops is also present, though its sleep benefit isn't established for an arbitrary extract.
How this product is rated for Sleep Support
Ingredient fit85
Valerian, GABA and passionflower are the three ingredients with possible sleep roles, led by valerian; hops has no independent sleep benefit established for an arbitrary extract.
Goal fit
The formula is focused on calming ingredients; the listed hops extract doesn't add an independently established sleep role.
Dose adequacy
The selected two-capsule serving lists 600 mg valerian extract, 200 mg GABA and 200 mg passionflower; these are serving amounts, not a verified daily total.
Pathways44
The blend maps to neural calming, with no separate timing or precursor route.
Depth
Valerian, GABA and passionflower all map to calming, with valerian providing the largest possible contribution.
Breadth
The ingredients point to one calming route rather than several distinct sleep processes.
Evidence51
Valerian has the clearest possible sleep role, but the generic extract details leave its specific contribution uncertain.
Evidence strength
Valerian is the strongest possible contributor here, though its extraction details don't identify a specific medicinal preparation.
Studied preparation
The passionflower extract is not specifically identified, so its amount cannot be matched confidently to a sleep preparation.
Formulation logic100
The credited calming ingredients can stand alone; no configured bedtime conflict is present.
Partner coverage
Valerian, GABA and passionflower don't require a partner for the roles described here; hops gets no separate credit.
Conflicts
Valerian, GABA, passionflower and hops do not trigger a configured activating conflict.
Effective doses
The listed amounts for valerian, GABA and passionflower each contribute here, but that doesn't establish a sleep effect for all three.
Impact
Highest effect
GABA · 200 mg
GABA may help with short-term responses to stressful tasks, while valerian has inconsistent findings in selected anxiety and sleep settings. Passionflower has some support for acute or procedural anxiety, but its 200 mg serving is below the amount described in the supplied procedural trial. Hops serves as a valerian partner in combination findings. These ingredient roles do not establish lasting everyday stress relief.
How this product is rated for Stress Relief
Ingredient fit89
GABA, valerian and passionflower provide a focused connection to stress-related anxiety and calming.
Goal fit
GABA, valerian and passionflower provide a focused connection to stress-related anxiety and calming.
Dose adequacy
Valerian meets the full amount reference, GABA is near it, and passionflower has a smaller amount contribution.
Pathways60
Calming is the strongest area, with a smaller sleep-related finding.
Depth
Calming receives the strongest finding from GABA, valerian and passionflower.
Breadth
Calming alone meets the coverage criterion; sleep recovery and the other evaluated areas do not.
Evidence86
GABA leads the saved evidence finding, although its stress findings concern limited short-term settings.
Evidence strength
GABA supplies the leading evidence contribution among the included ingredients.
Studied preparation
GABA and valerian receive preparation recognition; passionflower does not match a studied preparation in the saved finding.
Formulation logic100
The included contributions have their required partners or can stand alone, with no evaluated conflict identified.
Partner coverage
No required partner is missing for the included contributions.
Conflicts
No evaluated ingredient conflict was identified in the supplied facts.
Effective doses
All ingredients retained in this finding meet the saved minimum amount criterion; this does not establish a clinically effective dose.
