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

Nutrient Quality20

The GABA preparation is not stated. Its quality and match to particular studied preparations remain uncertain.

Ingredient Transparency63

The GABA amount is stated, but its form is omitted. The exact preparation therefore remains unclear.

Value For Money70

The GABA serving offers reasonable value. That favorable cost does not resolve uncertainty about the exact preparation or expected benefit.

Customer Satisfaction85

Customer feedback is highly positive across thousands of ratings. The response count gives useful context for satisfaction.

Product Focus64

The clearest possible benefit is short-term calming in specific stressful settings. Lasting stress relief, improved mood and better sleep remain uncertain for this preparation.

GABA · 250 mg

GABA may help with short-term responses to stressful tasks. This serving supplies 250 mg, meeting the saved quantity reference and giving a focused contribution to calming. Findings from food preparations and narrow settings do not establish sustained supplement benefit. The supplied results do not extend this contribution to mood-related functions, stress-response regulation or sleep recovery.

How this product is rated for Stress Relief

Ingredient fit96

GABA is the sole relevant active and meets the saved quantity reference.
Goal fit
GABA supplies the focused goal contribution. The product is also linked to other goals.
Dose adequacy
GABA's amount meets the saved quantity reference per selected serving.

Pathways60

The contribution is concentrated in calming, with no qualifying breadth into other aspects.
Depth
Calming is the strongest-covered aspect.
Breadth
Only calming reaches the saved breadth threshold.

Evidence91

GABA supplies the qualifying evidence contribution and meets the saved preparation requirement.
Evidence strength
GABA provides the qualifying evidence contribution; the amount comparison does not establish an individual benefit.
Studied preparation
The qualifying ingredients meet the saved preparation requirement; this does not establish that the whole product was tested.

Formulation logic100

The qualifying ingredients have no missing configured partners or identified conflicts and clear the saved amount threshold.
Partner coverage
The qualifying ingredients can contribute alone or have their configured partners present.
Conflicts
No configured ingredient conflict was identified in the supplied findings.
Effective doses
GABA clears the saved minimum contribution threshold; that threshold is not a proven effective dose.

B+ Ingredient FitF PathwaysD+ EvidenceA+ Formulation Logic

GABA may offer a modest calming role, but its contribution to better sleep remains uncertain. The product provides no separate sleep-timing ingredient, so its possible benefit rests on GABA alone.

The 250 mg serving gives GABA a possible contribution, but the amount doesn’t establish a clear sleep benefit. Its exact preparation isn’t specified in the ingredient details.

How this product is rated for Sleep Support

Ingredient fit83

GABA is the only sleep-focused ingredient, with no second contributor for timing or another sleep process.
Goal fit
GABA is the only sleep-focused ingredient, with no off-goal active adding another role.
Dose adequacy
The selected serving is one capsule, totaling 250 mg; that doesn’t establish a stronger sleep benefit.

Pathways9

The 250 mg serving provides a possible GABA contribution, but doesn’t establish a stronger sleep effect.
Depth
GABA supplies a limited calming role, without separate body-clock support.
Breadth
No second sleep process contributes alongside GABA.

Evidence51

GABA is the sole candidate for sleep support, and its role remains uncertain.
Evidence strength
GABA is the only candidate, but its contribution to better sleep remains limited.
Studied preparation
The label names Pharma GABA; no separate preparation detail changes its sleep role.

Formulation logic100

The label identifies Pharma GABA as the only active ingredient; no partner role is required.
Partner coverage
GABA is treated as able to contribute without a partner ingredient.
Conflicts
No listed ingredient creates a bedtime sleep conflict.
Effective doses
The 250 mg serving may contribute to GABA’s possible calming role, but it doesn’t guarantee better sleep.

GABA is involved in calming nerve signals, but taking it by mouth does not necessarily improve mood. The declared isolated GABA cannot be assumed to work like a particular GABA-containing fermented extract. Whether this preparation helps everyday emotional well-being remains unclear, despite the ingredient’s role in the nervous system.
