Product analysis
GABA 500 mg may help with short-term calming, but evidence for lasting stress relief or better sleep remains limited.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality27
The GABA preparation is unnamed, making it difficult to match to preparation-specific findings. Vitamin B6 is identified, but its comparative form quality remains uncertain.
Ingredient Transparency81
Both ingredient amounts are stated clearly. Vitamin B6’s form is named, while the GABA preparation is not, limiting comparisons with other GABA supplements.
Value For Money78
The GABA contribution offers favorable value at the serving cost. Value for vitamin B6 remains uncertain without a usable comparison.
Customer Satisfaction91
Customer ratings are very positive across a very large review base. The broad feedback shows satisfaction without establishing lasting benefits for stress or sleep.
Product Focus64
GABA is the main possible calming ingredient, with evidence limited to small and specific settings. The modest vitamin B6 contribution does not add a meaningful separate role for sleep.

GABA is associated with calming signals, but swallowing it doesn't necessarily improve everyday mood. Benefits from a particular fermented preparation can't be assumed for every GABA ingredient. Whether this preparation helps you feel less tense or improves emotional well-being remains unclear.
How this product is rated for Mood Support
Ingredient fit96
GABA supplies the main mood connection. Its practical contribution depends on the context described here.
Goal fit
GABA supplies the main connection with mood here.
Dose adequacy
GABA provides 500 mg per serving. The amount alone does not predict mood improvement.
Pathways17
The main connection is with calming signals; that connection alone does not guarantee feeling calmer.
Depth
The main connection is with calming signals; that connection alone does not guarantee feeling calmer.
Breadth
The ingredients relate to particular mood processes; this does not predict a broad improvement in emotional well-being.
Evidence53
Effects of a particular fermented GABA preparation cannot automatically be transferred to generic GABA.
Evidence strength
Effects of a particular fermented GABA preparation cannot automatically be transferred to generic GABA.
Studied preparation
Ingredient identity alone does not remove the limits on who may benefit.
Formulation logic100
No particular ingredient conflict is identified, and no additional partner is required by the described ingredient relationships.
Partner coverage
No additional partner is required by the ingredient relationships described here.
Conflicts
No particular conflict between the declared ingredients is identified.
Effective doses
GABA provides 500 mg per serving. A declared amount does not guarantee an individual benefit.
Impact
Moderate effect
GABA may offer some calming support that could help with winding down, though its direct contribution to better sleep remains uncertain. The product's 500 mg GABA serving is the clearest sleep-related ingredient.
Vitamin B6 is also listed, but its 2 mg amount is too small to add a meaningful separate role. The formula therefore stays focused on GABA's possible calming contribution.
How this product is rated for Sleep Support
Ingredient fit96
GABA is the only active with a meaningful sleep-related role here; the listed vitamin B6 amount is too small to add another.
Goal fit
GABA is the only credited sleep-related ingredient; vitamin B6 doesn't add a meaningful role at the listed amount.
Dose adequacy
The serving provides 500 mg GABA and 2 mg vitamin B6; the small B6 amount isn't counted as a sleep contribution.
Pathways12
GABA's possible contribution is calming, while the formula doesn't provide a distinct timing or sleep-signaling role.
Depth
GABA's possible role is calming, which may help with winding down before sleep.
Breadth
The formula has a calming role but doesn't add distinct support for sleep timing or signaling.
Evidence51
GABA may offer some calming support, but its direct role in better sleep remains uncertain.
Evidence strength
GABA may offer some calming support, though its direct contribution to better sleep remains uncertain.
Studied preparation
The label names GABA but no special preparation, so its possible sleep role remains general.
Formulation logic100
GABA can contribute on its own here; the small B6 amount doesn't add a second meaningful sleep role.
Partner coverage
GABA is treated as able to contribute on its own; no partner is required.
Conflicts
No listed ingredient is identified as working against sleep.
Effective doses
GABA has a stated 500 mg amount; the 2 mg B6 serving is too small to add a separate role.

GABA · 500 mgVitamin B6 · 2 mg
GABA may help with short-term responses to stressful tasks. The supplied findings come from small, narrow settings and food preparations, so sustained everyday relief from a supplement remains uncertain. The declared serving reaches the comparison amount, but a larger quantity does not establish a stronger or more lasting effect.
How this product is rated for Stress Relief
Ingredient fit96
The declared relevant ingredients are focused on stress-related uses, with no unrelated actives reducing that focus. The counted amounts reach the comparison anchors; larger amounts do not establish stronger or more lasting relief.
Goal fit
The declared relevant ingredients are focused on stress-related uses, with no unrelated actives reducing that focus.
Dose adequacy
The counted amounts reach the comparison anchors; larger amounts do not establish stronger or more lasting relief.
Pathways60
The clearest contribution concerns neural calming. Other processes are represented to differing degrees by this serving.
Depth
The strongest supplied finding concerns neural calming, without proving a lasting clinical effect.
Breadth
The broader findings chiefly cover neural calming.
Evidence91
GABA leads the counted evidence. Recognized preparations are present, with benefit limited by the study contexts described above.
Evidence strength
GABA supplies the strongest counted evidence; its specific study limitations still govern expectations for relief.
Studied preparation
The counted preparations match those recognized by the supplied comparison, without establishing that all studies or populations match this product.
Formulation logic100
The counted ingredients have their relevant partners or stand alone, and no configured conflict was found. Their amounts reach the minimum comparison benchmark.
Partner coverage
The counted ingredients either work independently in this comparison or have their relevant partner present.
Conflicts
No configured ingredient conflict was found in the supplied findings.
Effective doses
All counted ingredients meet the minimum amount benchmark; this is not a proven effective dose for lasting stress relief.
