Analysis

Melatonin at 2 mg provides the clearest support for sleep timing. Seven additional calming ingredients are present, but most are limited to 100 or 150 mg and the botanical extracts lack active-marker detail.

L-tryptophan and GABA are each supplied at 100 mg, modest amounts within a combination. The long ingredient list may produce additive sedation without establishing a strong dose for any one non-melatonin pathway.

Two capsules are convenient, while serving value is only moderate. It fits users who prefer a broad low-to-moderate-dose blend rather than a focused, standardized botanical product.

Who is it for
  • Adults seeking nighttime sleep support
  • People who want several calming pathways in one formula
  • Users not taking serotonin-raising medicines
Best for
  • Bedtime relaxation
  • Sleep-onset support
  • Broad bedtime calming with moderate melatonin

Pros

  • Uses 2 mg melatonin
  • Lists all calming ingredients individually
  • Combines several familiar nighttime herbs
  • Requires two capsules

Cons

  • Most supporting ingredients are modestly dosed
  • Botanical potency is not standardized
  • Breadth exceeds depth
  • Serving value is only moderate

Warnings

  • Tryptophan may interact with SSRIs, SNRIs, MAO inhibitors, or other serotonin-raising medicines.
  • The combined calming ingredients may cause substantial drowsiness; do not drive after use.
  • Alcohol, sedatives, and other sleep medicines can intensify the formula’s effects.

Nutrient quality

77 High impact

The ingredients use basic forms with little standardization or purity information; melatonin is useful, while valerian and tryptophan are relatively modest. Individual amounts are moderate, though the long sedating combination may increase drowsiness; the formula consistently targets sleep and relaxation; most additions serve the bedtime purpose despite limited potency detail.

.

Ingredient transparency

74 High impact

Every listed active has a specific amount; no proprietary blend hides key doses. Ingredient names are clear at a basic level, but botanical species, plant parts, and markers are mostly missing; serving directions and inactive ingredients are not included in the supplied details.

.

Customer satisfaction

65 High impact

The supplied aggregate average is only moderate, and no individual feedback is available; the large rating sample improves confidence in the aggregate average, but no individual feedback is supplied. Detailed feedback is absent, so repeated complaints cannot be assessed; real-world fit with the intended purpose remains uncertain.

.

Value for money

76 High impact

The broad but basic blend offers fair formula value; the serving cost is moderate for the number of actives. Few additions are clearly unrelated to sleep; the product is reasonably positioned among multi-herb sleep blends.

The formula directly targets sleep with melatonin, GABA, tryptophan, and several calming botanicals. Circadian and relaxation pathways are both covered, but evidence is strongest for melatonin.

Several herbal and amino-acid amounts are modest, so the long list offers more breadth than depth. The combined sedating ingredients may cause substantial drowsiness and can add to the effects of alcohol, sleep medicines, or other central nervous system depressants.

GABA, tryptophan, and several calming herbs provide broad nighttime relaxation support, while melatonin helps set sleep timing. Evidence varies across the ingredients, and the formula is better aligned with stress-related sleep difficulty than daytime resilience.

Most calming ingredients are present at modest amounts, and botanical standardization is not disclosed. Their combined sedating effects may substantially reduce alertness, while tryptophan can also interact with serotonin-raising medicines such as SSRIs or MAO inhibitors.

D+ Goal FitF Strength of SupportD+ CoverageC Formula Quality

The blend may support mood indirectly by improving relaxation and sleep, but most actives are below focused supplemental ranges. Melatonin and multiple calming botanicals make it a sleep product rather than a broad mood-regulation formula.

Tryptophan offers a serotonin-precursor pathway, yet its 100 mg amount is small and oral GABA has limited brain access. The combined sedatives may cause substantial drowsiness, so the product is unsuitable before driving or when combined with other sleep medicines or alcohol.

Report overview
GABA · 100 mg OverallScore73
B- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD- Value
The disclosed GABA amount is appropriate for a complex sleep blend, though its unbranded source is not premium. Two capsules provide standard delivery without a special absorption system. Valerian, tryptophan, chamomile, passionflower, lemon balm, hops, and melatonin may combine to cause substantial drowsiness and reduced alertness.
Melatonin · 2 mg OverallScore54
F Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyD Value

The melatonin amount fits a conservative range that may support sleep onset without relying on a high dose. Several calming ingredients broaden the formula, but the standard capsules do not provide fast-dissolve or sustained-release delivery. The complex blend partly explains the premium price, while missing independent purity verification remains a drawback.

Valerian · 150 mg OverallScore51
C- Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyF Value

The capsule format keeps valerian's strong sensory profile contained and clearly lists a 150 mg extract dose. Extract potency is uncertain because no concentration ratio or valerenic-acid standardization is supplied. The low dose and high cost make it a weak fit when valerian content is the main priority.
