44 out of 100

Sleep+ Calm Strawberry uses melatonin to support sleep timing and may help you fall asleep sooner. Its unnamed herbal blend makes the complete formula harder to compare.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality20

The unspecified ingredient forms leave preparation quality uncertain. The unnamed herbal blend also prevents a clear judgment of its components.

Ingredient Transparency50

Serving amounts are listed, but ingredient forms are unspecified. The herbal blend total does not identify its individual components.

Value For Money45

Melatonin offers moderate value, while theanine is expensive for the amount provided. Carbohydrate value remains uncertain, making the full formula less straightforward to judge on cost.

Customer Satisfaction89

Customer feedback is very positive across thousands of ratings. The broad review base describes satisfaction without proving better sleep.

Product Focus40

Melatonin provides the clearest support for sleep timing. The small theanine serving and unresolved herbal ingredients do not establish additional sleep benefits.

A Ingredient FitD+ PathwaysA+ EvidenceA+ Formulation Logic
Melatonin · 0.5 mgTheanine · 25 mg

Melatonin supports sleep timing and may shorten sleep onset; low amounts have been studied, without establishing a universal optimal dose. Theanine at 25 mg per serving adds no counted contribution here. Chamomile and lemon balm remain unresolved because the stored label claims and imported inventory disagree, so their presence and amounts cannot support an additional benefit.

How this product is rated for Sleep Support

Ingredient fit90

Melatonin provides the counted contribution. Theanine is too limited for inclusion, and the herbal declarations remain unresolved.
Goal fit
The counted ingredients connect to sleep; links to other goals also influence how focused the formula is.
Dose adequacy
Some amounts receive a smaller contribution, limiting the overall amount-based support without proving those ingredients ineffective.

Pathways53

The strongest connection is circadian timing. The wider coverage is concentrated in circadian timing.
Depth
Circadian timing is the strongest represented route in the saved findings.
Breadth
The broader coverage is concentrated in circadian timing; other routes do not reach the same level.

Evidence100

Melatonin carries the strongest evidence among the counted ingredients. The counted preparations are recognized as studied.
Evidence strength
Melatonin provides the strongest evidence among the counted ingredients; this does not predict the size of an individual sleep benefit.
Studied preparation
The saved findings recognize the counted preparations as studied; this does not guarantee equivalent effects across regimens or populations.

Formulation logic100

No missing partner or listed ingredient conflict limits the counted contributions. All counted ingredients meet the saved amount criterion.
Partner coverage
The counted ingredients can contribute without a missing companion ingredient.
Conflicts
No listed conflict was identified at the supplied amounts.
Effective doses
All counted ingredients meet the saved amount criterion; this does not make every included amount a proven effective sleep dose.
