Criterios de evaluación

Quantity
100 / 100
At one tablet, 2.5 mg melatonin is a useful supplemental amount, alongside magnesium and other sleep-support ingredients; this is adequate for the stated supplemental role.
Form
65 / 100
Oral melatonin and the listed amino acids are conventional forms, but the magnesium compound is not identified, leaving a relevant absorption and tolerability property unresolved.
Convenience
100 / 100
The label permits 1–2 tablets; one tablet supplies half the two-tablet serving, including 2.5 mg melatonin, a reasonable starting supplemental amount.
Label accuracy
100 / 100
The matched label gives amounts for the listed ingredients and directions without an evident contradiction or unsupported claim.
Formula balance
75 / 100
The combination is ordinary for a multi-ingredient sleep formula, with no established compatibility advantage or concrete mismatch evident from the label.
Purity
75 / 100
No product-specific testing or other evidence establishes above-ordinary purity or a concrete defect.
Cofactors
0 / 100
The additional ingredients are part of the co-primary sleep formula rather than separately quantified supporting cofactors.
