Analysis

Suntheanine and GABA are each supplied at 100 mg, creating a concise two-pathway calming core. Liquid delivery supports flexible and easy use for people who avoid capsules.

Glycine at 50 mg is far below gram-level sleep use and adds little independent depth. GABA is clearly dosed but lacks a branded fermented source or enhanced-delivery detail.

The three-active formula avoids stimulants and is easy to understand. Only 29 servings and a high serving cost make value weak compared with simpler theanine or GABA products.

Who is it for
  • Adults seeking a liquid calming formula
  • People who value Suntheanine
  • Users who avoid capsules
Best for
  • Short-term stress relief
  • Evening relaxation
  • Flexible liquid dosing

Pros

  • Uses 100 mg Suntheanine
  • Provides 100 mg GABA
  • Simple stimulant-free formula
  • Liquid format

Cons

  • Glycine amount is tiny
  • Very high serving cost
  • Only 29 servings
  • GABA source is not premium identified

Warnings

  • Theanine and GABA may cause drowsiness
  • Alcohol or sedative medicines may increase the calming effect
  • Avoid driving until individual response is known

Nutrient quality

84 Highest impact

<p>Branded Suntheanine supports form quality, while GABA and glycine use conventional forms. Theanine is meaningful, but GABA and glycine remain modest for standalone use.</p>.

Ingredient transparency

81 Highest impact

<p>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.</p>.

Customer satisfaction

53 Moderate impact

<p>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.</p>.

Value for money

45 Lower impact

<p>Quality, safety trade-offs, or serving economics materially weaken value. The focused three-active formula shows no low-value padding.</p>.

B+ Goal FitB- Strength of SupportB CoverageA+ Formula Quality

Branded theanine provides direct calm-focus support, while GABA adds an inhibitory signaling pathway. The liquid format allows flexible use and each active is clearly listed.

Glycine is far below sleep-support amounts and oral GABA evidence remains less consistent because brain uptake is uncertain. The compact formula is still logically built for short-term relaxation without stimulants.

C+ Goal FitD+ Strength of SupportD+ CoverageA Formula Quality

L-theanine and GABA target mental relaxation, while glycine adds a separate sleep-related mechanism. The concept is coherent, but the ingredient amounts are mostly modest.

Branded Suntheanine is a quality strength and GABA is clearly dosed. Glycine at 50 mg is far below the gram-level amounts used in sleep research, and oral GABA has uncertain brain availability.

Report overview
GABA · 100 mg OverallScore66
B- Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

A clearly disclosed 100 mg GABA dose fits a multi-ingredient calming liquid, but the source is not identified as fermented or branded. Liquid delivery is convenient, while the lack of liposomal or sublingual detail limits confidence in enhanced absorption. The high serving cost and incomplete excipient disclosure weaken value.

Glycine · 50 mg OverallScore64
C- Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyB- Value

The liquid includes only a small glycine amount within a calming blend. Liquid dosing is convenient for this use, but it is impractical for reaching typical high-dose glycine targets, and source purity is unverified. Branded theanine and GABA support neutral full-formula value despite very poor glycine-specific efficiency.
