A straightforward once-nightly melatonin capsule at a reasonable supplemental dose, though its listed supporting ingredients do not establish a special advantage.

Scoring criteria

Quantity
100 / 100
The labelled 5 mg melatonin serving is a reasonable supplemental amount for the stated sleep-support role.
Form
75 / 100
This is conventional oral melatonin in a capsule, with no established absorption or tolerability advantage over ordinary melatonin preparations.
Convenience
100 / 100
The label directs one capsule 30–60 minutes before bedtime; the 60-capsule package provides 60 daily units.
Label accuracy
100 / 100
The labelled serving, melatonin amount and stated gluten-free, non-GMO and vegetarian claims show no contradiction in the supplied information.
Purity
75 / 100
The supplied label lists ordinary excipients and provides no specific independent purity testing or contaminant-control evidence.
Cofactors
50 / 100
The separately declared 120 mg magnesium is a meaningful supporting amount with a plausible complementary role, though added benefit alongside melatonin is uncertain.
