Analysis

The capsule supplies PharmaGABA, valerian, and a low melatonin amount suited to sleep onset. The supplied data shows duplicate 0.75 mg melatonin entries, so the physical label should be checked to confirm whether the total is 0.75 mg or 1.5 mg.

PharmaGABA is a useful branded source, but 100 mg is at the low end, while 50 mg of valerian is a supporting amount. The probiotic matrix lists only a 64 mg weight with no strains or viable-organism count.

One capsule is convenient, though the serving cost is high for the disclosed nighttime actives. The product mainly fits users who value low-dose melatonin and can verify both the melatonin total and probiotic specifications.

Who is it for
  • Adults seeking low-dose melatonin with PharmaGABA
  • Users who prefer one capsule
  • People who can verify the label’s melatonin total
Best for
  • Sleep-onset support
  • A low-dose melatonin routine
  • Combining PharmaGABA with mild valerian support

Pros

  • Uses branded PharmaGABA
  • Keeps melatonin relatively low
  • Identifies valerenic acids
  • Uses one capsule
  • Combines calming and probiotic concepts

Cons

  • Valerian is lightly dosed
  • The probiotic matrix hides strains and viable count
  • Duplicate melatonin entries create ambiguity
  • Serving cost is high
  • No extended-release feature is stated

Warnings

  • Verify whether the duplicate melatonin entries represent one total or two separate amounts before use.
  • Melatonin, GABA, and valerian may add to alcohol or sedative medicines and cause excess drowsiness.
  • Do not drive or operate machinery after taking the capsule.
  • People with severe immune compromise should seek guidance before using an unspecified live-microorganism blend.

Nutrient quality

71 High impact

Branded PharmaGABA and marker-named valerian improve form quality within the sleep blend. The melatonin amount is restrained, while GABA and valerian provide only modest supporting doses.

.

Ingredient transparency

56 Moderate impact

Named sleep actives have amounts, but the probiotic matrix is not fully quantified by strain. The proprietary probiotic matrix hides strain-level amounts and viable-organism details.

.

Customer satisfaction

57 Moderate impact

The supplied aggregate rating is mixed, and no specific comments explain the result. The large rating count makes the aggregate result relatively stable.

.

Value for money

50 Moderate impact

Formula quality provides reasonable support for the product positioning. Serving utility appears weak, while low-value or lightly dosed extras reduce efficiency.

Melatonin · 0.75 mg

Melatonin, PharmaGABA, and standardized valerian address circadian signaling, relaxation, and botanical calming in one bedtime capsule. The combination is sleep specific and uses clearly identified active forms.

GABA at 100 mg and valerian at 50 mg are modest, so melatonin likely carries much of the practical effect. Combining all three calming agents may cause excess drowsiness, and the proprietary probiotic matrix adds uncertain sleep value.

GABA · 100 mg

Branded PharmaGABA, valerian, and low-dose melatonin create a targeted nighttime calming formula. The combination may help when stress mainly appears as difficulty winding down, but it is less suited to daytime stress relief.

GABA is present at a modest blend dose, while the valerian amount is quite low despite active-marker disclosure. Combining these calming agents with melatonin may increase drowsiness, so the capsule is best reserved for bedtime.

C- Goal FitC+ Strength of SupportC CoverageC+ Formula Quality

Low-dose melatonin, PharmaGABA, and valerian support sleep and relaxation, which may improve cognitive recovery. A probiotic matrix adds a possible gut-brain component.

The probiotic blend lacks strain and viable-organism details, while valerian is modest and its active standardization is unclear. Combining melatonin, GABA, and valerian may cause nighttime or next-morning drowsiness in sensitive users.

Report overview
GABA (PharmaGABA) · 100 mg OverallScore78
A Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyD- Value

Branded fermented PharmaGABA provides a well-defined source, but the amount is at the low end and is delivered in a standard capsule. Melatonin and valerian make the blend more specific to nighttime use and may add drowsiness. The premium source is offset by weak value per serving.

A+ Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyF Value

Valerenic acids are specifically identified, which gives useful insight into the active portion of the valerian ingredient. The 50 mg valerian amount is low for a dedicated valerian supplement, even though one capsule keeps use simple. Valerian combined with melatonin and GABA may cause drowsiness, so the high serving cost is difficult to justify for routine use.

Melatonin · 0.75 mg OverallScore64
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyC Value

The 0.75 mg dose is physiologically aligned and clearly provided in one capsule. Standard capsule delivery and immediate release favor sleep onset more than overnight maintenance. The multi-ingredient sleep formula partly supports its premium cost, but independent purity certification is absent.
