49 out of 100

Liposomal GABA may help with short-term tension and some aspects of sleep quality through GABA and theanine. Its liposomal description does not establish an extra sleep benefit.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality22

GABA and theanine are not identified by form, limiting a closer quality comparison. The sunflower source of the third ingredient is named, but its form quality remains uncertain.

Ingredient Transparency75

All ingredient amounts are stated. GABA and theanine forms are unspecified, while the sunflower-derived ingredient has a named source.

Value For Money40

GABA offers limited value at the full serving cost. Value for theanine and the sunflower-derived ingredient remains uncertain.

Customer Satisfaction53

The few available ratings suggest moderate satisfaction. Such a small set may not reflect wider customer experience.

Product Focus77

The formula has a focused connection to short-term tension and sleep quality. The limited findings do not establish lasting stress relief or an added benefit from combining the ingredients.

GABA · 240 mgTheanine · 100 mg

GABA and theanine may help with short-term task-related stress and tension. GABA findings come from limited studies in narrow settings, while theanine has direct relaxation findings with mixed sustained mood and anxiety results. Their presence together does not establish an additional combined benefit or lasting everyday stress relief.

How this product is rated for Stress Relief

Ingredient fit79

GABA and theanine supplies the main practical connection to stress relief. The serving amounts are interpreted within the supplied guidance.
Goal fit
GABA and theanine supplies stress relevance within a formula containing ingredients aimed at other goals.
Dose adequacy
GABA and theanine has a known serving amount that contributes to the saved findings; the amount guidance does not prove an effective daily regimen.

Pathways60

Calming-related functions provide the main connection to stress relief.
Depth
GABA and theanine provides the strongest connection through calming-related functions.
Breadth
Calming is the main represented function; other stress-related functions are less supported.

Evidence91

GABA and theanine anchors the evidence, with the preparation, population and outcome limitations described for those ingredients.
Evidence strength
GABA leads the saved evidence finding; the supplied limitations still restrict how broadly its benefit can be described.
Studied preparation
GABA and theanine is accepted as studied in the saved findings; this does not establish equivalent effects for every formulation.

Formulation logic100

The credited ingredients retain their individual contributions and no evaluated conflict was triggered. This does not establish synergy.
Partner coverage
The credited ingredients retain their individual contributions without requiring an additional missing partner.
Conflicts
No evaluated formulation conflict was triggered by the supplied facts.
Effective doses
All credited ingredients meet the saved amount threshold, which is an inclusion rule rather than a proven clinical effect.

Theanine Supportive 16 studies

Theanine · 100 mg

L-theanine may help with some aspects of sleep quality, although small trials do not establish an immediate sedative effect. GABA has limited sleep evidence from particular preparations, and oral GABA should not be assumed to mirror its activity in the brain. The supplied amounts use a 2 mL serving; the liposomal description does not establish additional sleep benefit.

How this product is rated for Sleep Support

Ingredient fit71

Theanine and GABA provide the sleep-related focus, with moderate support from their declared amounts.
Goal fit
Theanine and GABA are sleep-related, while another active and broader goal links reduce focus.
Dose adequacy
The 2 mL serving supplies amounts receiving partial support for theanine and GABA, rather than their fullest amount allowance.

Pathways41

The saved findings center on calming, with a smaller stress-related contribution.
Depth
Calming is the strongest aspect in the saved findings.
Breadth
Calming alone meets the saved coverage threshold; the stress-related finding is smaller.

Evidence86

Theanine provides the stronger evidence, while GABA's sleep findings remain limited and preparation-specific.
Evidence strength
Theanine supplies the strongest evidence among the counted ingredients, based on limited trials of some sleep outcomes.
Studied preparation
Both ingredients receive preparation recognition, but GABA trials do not establish equivalence or extra benefit for this liposomal product.

Formulation logic100

The counted ingredients do not require a missing partner, and no configured conflict was found.
Partner coverage
The counted ingredients can contribute without a missing partner; no extra benefit from combining them is established.
Conflicts
No configured ingredient conflict was identified in the supplied findings.
Effective doses
Both counted ingredients meet the saved amount threshold, without establishing a proven effective dose for this product.
