Analysis

GABA at 125 mg supplies the main calming ingredient in a dissolving format. The lozenge may suit occasional use when portability and quick administration matter.

Glycine, magnesium, taurine, and N-acetyl tyrosine are present at very small amounts. Those doses do not provide meaningful standalone support, and tyrosine may feel activating for some users.

Sixty servings and low cost create good practical value. The product works better as a simple GABA lozenge than as a deep multi-pathway sleep formula.

Who is it for
  • Adults seeking occasional calming support
  • People who prefer dissolving lozenges
  • Value-focused GABA users
Best for
  • Occasional stress relief
  • Portable calming support
  • Users who want a modest GABA amount

Pros

  • Provides 125 mg GABA
  • Convenient dissolving format
  • Offers 60 servings
  • Low serving cost

Cons

  • Glycine amount is tiny
  • Magnesium and taurine are token doses
  • GABA source is unbranded
  • Tyrosine may feel activating

Warnings

  • GABA may cause drowsiness; avoid driving until individual response is known
  • Combining with alcohol, sedatives, or sleep medicines may increase drowsiness
  • Tyrosine may interact with MAO inhibitors or thyroid medicines

Nutrient quality

75 High impact

A chelated magnesium form is named, while the amino acids use conventional forms without premium sourcing. GABA is useful for a calming blend, but glycine, tyrosine, taurine, and magnesium are very small.

.

Ingredient transparency

79 High impact

Active amounts are stated and no proprietary blend hides a core dose. Missing excipient details and complete use directions leave the supplied label information incomplete.

.

Customer satisfaction

62 Moderate impact

The supplied aggregate satisfaction average provides a broad signal, while the response volume determines how stable it appears. No comment-level evidence is available to assess repeated complaints or confirm intended-use experiences.

Value for money

85 Highest impact

Useful active delivery supports favorable serving value. Several token supporting amounts add limited value beside GABA.

GABA provides the main calming action, while glycine and taurine offer related inhibitory-neurotransmitter support. The lozenge format may help oral absorption and is suited to occasional acute use.

Most supporting ingredients are present in very small amounts, so the practical effect depends heavily on GABA. GABA, glycine, and taurine may reduce alertness, making the lozenge unsuitable before driving or hazardous work until individual response is known.

Magnesium · 5 mgGlycine · 50 mg

GABA and several amino acids give the lozenge a relaxation-oriented design, but most amounts are too small to provide convincing depth. Magnesium, glycine, and taurine are present far below commonly meaningful standalone amounts.

The blend nominally touches several pathways without directly supporting circadian timing. N-acetyl L-tyrosine may also be more alerting than calming for some users, which weakens its nighttime logic.

B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD- Value

The 125 mg amount suits a complex calming blend, but reaching a standalone amount would make value weak. Lozenge delivery may support absorption through the mouth, while the GABA source lacks fermented-brand verification. GABA, glycine, taurine, and N-acetyl tyrosine may alter alertness, so the lozenge is better suited to times without driving or hazardous work.

F Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyF Value

The formula is poorly suited to a glycine-focused goal because each lozenge supplies only a very small amount. The label clearly identifies the glycine amount, but it gives no purity grade or sourcing details. The lozenge format is convenient, yet obtaining a meaningful glycine intake would require many servings and offers weak value.
