Scoring criteria

Quantity
100 / 100
The labelled 3 mg melatonin serving is within a reasonable supplemental range for the stated sleep-support role.
Form
75 / 100
The product identifies immediate-release melatonin, a conventional form appropriate to bedtime use but without an established comparative absorption advantage over ordinary immediate-release melatonin.
Convenience
100 / 100
The labelled routine is one capsule 30–60 minutes before bedtime, and the product title states a 60-capsule package.
Label accuracy
100 / 100
The matched label clearly declares the melatonin amount and serving, with no established amount contradiction.
Purity
75 / 100
No product-specific testing or other evidence of exceptional purity or a concrete purity defect is supplied.
Cofactors
0 / 100
No separately quantified ingredient is established as a meaningful complementary sleep-support cofactor; the listed inositol amount is 100 mg.
