This is a modest-dose GABA lozenge for buyers seeking a simple calming supplement, but the label does not establish a strong added benefit from its minor amino acids.

Scoring criteria

Quantity
75 / 100
Three lozenges provide 375 mg of GABA daily, which is a moderate but not clearly robust supplemental amount for calming support.
Form
75 / 100
GABA is delivered in a dissolving oral lozenge, but this route has no established practical absorption advantage over ordinary oral GABA.
Convenience
63 / 100
The smallest labelled routine likely to provide a practical supplemental GABA amount is one 125 mg lozenge three times daily, for 375 mg per day.
Label accuracy
100 / 100
The quantified ingredients and serving information are internally consistent with the matched FDA label.
Purity
75 / 100
The label lists ordinary excipients and provides no product-specific testing or contamination evidence.
Cofactors
0 / 100
Glycine, N-acetyl L-tyrosine, taurine, and magnesium are present only at small amounts without established added benefit at this dose.
