Product analysis
Goodbye Stress Berry Verbena may help with short-term tension, although lasting stress and mood benefits remain uncertain. Theanine offers weak value for the amount supplied, which matters if it is the main reason for choosing the combination.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality20
The calming ingredients lack clearly disclosed preparation details. That limits comparisons with particular theanine, GABA and herbal preparations.
Ingredient Transparency63
Ingredient amounts are stated, making the serving easy to check. The forms remain unspecified, limiting a closer comparison of preparations.
Value For Money34
Theanine is expensive for the amount supplied, while GABA offers limited value. Value for the remaining ingredients is uncertain.
Customer Satisfaction78
Customer ratings are strongly positive across several hundred reviews. Satisfaction does not establish lasting stress or sleep benefits.
Product Focus67
The ingredients share a clear calming theme across stress and sleep. Limited evidence and small ingredient amounts leave lasting everyday benefits uncertain.

GABA · 100 mgTheanine · 50 mg
GABA has limited findings for short-term task stress, while theanine may ease tension during stressful tasks. The formula's connection is mainly to calming, with 50 mg theanine per serving below the 100 mg lower reference quantity in the supplied comparison. Lemon balm is present in a small amount below the saved inclusion threshold. Sustained everyday benefit remains uncertain for GABA, and theanine's longer-term mood findings are mixed.
How this product is rated for Stress Relief
Ingredient fit71
GABA and theanine provide the main focused connection to calming.
Goal fit
GABA and theanine provide the main focused connection to calming.
Dose adequacy
GABA and theanine supply partial reference amounts; lemon balm is too low to count.
Pathways44
Neural calming is the strongest represented role. Neural calming is substantially represented; other stress-related roles have limited coverage.
Depth
Neural calming is the strongest represented role.
Breadth
Neural calming is substantially represented; other stress-related roles have limited coverage.
Evidence91
GABA leads the saved evidence finding, but its short-term task-stress findings do not establish sustained supplement benefit.
Evidence strength
GABA leads the saved evidence finding, but its short-term task-stress findings do not establish sustained supplement benefit.
Studied preparation
The counted ingredients match preparations accepted in the saved comparison; that does not guarantee the same personal response.
Formulation logic100
The counted ingredients can contribute independently or have their required partner present.
Partner coverage

Conflicts
No configured ingredient conflict was identified.
Effective doses
All counted ingredients meet the saved amount threshold.
Impact
High effect
Theanine · 50 mg
Theanine may support reported sleep quality, with small studies involving repeated use rather than a guaranteed immediate sedative effect. The 50 mg per serving is below the 200 mg daily amount used in the supplied trial. GABA adds a tentative sleep-onset contribution, but supporting trials are small and do not show that oral GABA directly reflects brain GABA activity. Lemon balm has some sleep-quality support, but this serving is too small to be included in the saved findings.
How this product is rated for Sleep Support
Ingredient fit68
Theanine and GABA are relevant to sleep support, but their relatively small amounts limit the finding. Lemon balm is below the inclusion level.
Goal fit
Theanine and GABA give the formula a sleep-related focus, although it is linked to other goals too.
Dose adequacy
The amounts provide only partial support; theanine is below the daily amount in the supplied small trial.
Pathways11
The main connection is neural calming, with weaker stress-related coverage. Neither route reaches the saved substantial-coverage level.
Depth
Neural calming is the strongest route, supported by theanine and GABA, but coverage is limited.
Breadth
No route reaches the saved substantial-coverage level; stress-related support is weaker than neural calming.
Evidence86
Theanine leads the evidence finding, while GABA evidence is more limited. The saved findings recognize their preparations, but do not establish an immediate sleep effect.
Evidence strength
Theanine supplies the leading evidence contribution, based on small repeated-use studies.
Studied preparation
The saved findings recognize theanine and GABA as studied preparations; GABA’s precise trial preparation should not be assumed.
Formulation logic100
Theanine and GABA meet the saved inclusion criterion and have no missing required partners or listed activating conflicts. Lemon balm is not included.
Partner coverage
Theanine and GABA have no missing required partner in the saved findings.
Conflicts
No listed activating ingredient conflict was identified.
Effective doses
Theanine and GABA meet the saved inclusion criterion; lemon balm is too low to be included.
Impact
Moderate effect
Theanine may ease stress-related tension, but the 50 mg serving is below the amount associated with the clearest benefit. GABA adds uncertainty: its calming role in the body doesn't mean swallowed GABA improves everyday mood. There isn't a clear basis for expecting the combination to produce a lasting mood benefit.
How this product is rated for Mood Support
Ingredient fit70
Theanine may ease stress-related tension; a lasting mood benefit remains uncertain.
Goal fit
Theanine may ease stress-related tension; a lasting mood benefit remains uncertain.
Dose adequacy
A serving provides Lemon balm 75 mg, GABA 100 mg, Theanine 50 mg. These amounts don't guarantee a mood benefit.
Pathways11
The ingredients relate to mood through the roles described below; these roles do not predict an individual benefit.
Depth
The ingredients relate most closely to calming nerve activity, which is distinct from a reliable improvement in mood.
Breadth
The ingredients provide limited support across the mood-related roles considered.
Evidence61
Theanine may ease stress-related tension; a lasting mood benefit remains uncertain.
Evidence strength
Theanine may ease tension associated with mental stress, while a lasting mood benefit remains uncertain.
Studied preparation
The identified ingredient preparations permit comparison, but matching a preparation does not guarantee the same mood benefit.
Formulation logic100
No particular ingredient conflict or missing required partner is identified.
Partner coverage
No required ingredient partner is missing; this does not imply an added benefit from combining ingredients.
Conflicts
No particular ingredient conflict is identified.
Effective doses
The declared amounts are Lemon balm 75 mg, GABA 100 mg, Theanine 50 mg; they are not a guarantee of benefit.
