Analysis

GABA at 125 mg is the only ingredient supplied at a clearly useful blend-level amount. Dissolving delivery is convenient and may suit quick use better than a swallowed capsule.

Glycine at 50 mg, tyrosine at 25 mg, taurine at 20 mg, and magnesium at 5 mg provide little standalone depth. The activating role of tyrosine also makes the sleep design less coherent.

The 30-serving package has a low serving cost and a simple label. It should be viewed as a modest GABA lozenge rather than a comprehensive sleep or glycine formula.

Who is it for
  • Adults wanting a peppermint GABA lozenge
  • People seeking occasional relaxation
  • Users who prefer dissolving delivery
Best for
  • Short-term calming use
  • Portable GABA supplementation
  • Occasional evening relaxation

Pros

  • Provides 125 mg GABA
  • Convenient lozenge format
  • Low serving cost
  • Clearly lists every active amount

Cons

  • Glycine is far below a sleep dose
  • Magnesium and taurine are minimal
  • Tyrosine may be activating
  • GABA source quality is unspecified

Warnings

  • GABA may reduce alertness
  • Alcohol and sedative medicines may increase drowsiness
  • Tyrosine can interact with MAO inhibitors and 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

57 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

83 Highest impact

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

GABA directly targets inhibitory signaling, and the lozenge format may offer quicker use than a swallowed capsule. The amount is plausible within a calming blend, although evidence for ordinary oral GABA remains mixed.

Glycine, taurine, magnesium, and tyrosine are present at amounts too small to add much stress support. The formula is focused on acute calm but has uneven depth beyond its main active.

Magnesium · 5 mgGlycine · 50 mg

A lozenge supplies GABA with small amounts of glycine, magnesium, taurine, and tyrosine. The delivery format may suit quick pre-sleep use.

Glycine, magnesium, and taurine are far below meaningful sleep amounts, while tyrosine can be activating for some users. Most of the apparent pathway breadth is therefore too shallow to support sleep reliably.

The lozenge format may offer faster delivery than a swallowed capsule. Its unbranded GABA amount is reasonable within a calming blend, although it falls below the preferred standalone range. The low serving cost supports good value despite missing premium-source and excipient details.

The glycine amount is clear, but no premium grade, branded source, or purity certification is provided. Its 50 mg contribution is modest alone but works as part of the calming blend. High cost per gram limits value for anyone primarily seeking glycine.
