The labelled melatonin amount is a reasonable supplemental dose, but the undisclosed L-theanine amount and conflicting package count make the overall formula and jar size less certain.
Scoring criteria
Quantity
75 / 100Melatonin is 5 mg per serving, a reasonable supplemental amount, but the amount of co-primary L-theanine within the 214 mg blend is undisclosed, leaving adequacy of the combined formula unresolved.
Form
75 / 100Melatonin and L-theanine are conventional oral forms with no established comparative absorption or tolerability advantage identified here.
Convenience
85 / 100Assume one 2-capsule serving once daily because directions are not supplied; the title lists 14 capsules, while the panel describes 30 servings.
Label accuracy
75 / 100The listing title says 14 capsules, whereas the panel states 30 servings of 2 capsules, an unresolved package-count inconsistency.
Formula balance
75 / 100The combination is relevant to sleep support, but the undisclosed L-theanine amount prevents judging the balance of the co-primary ingredients.
Purity
75 / 100No product-specific purity testing or contaminant concern is provided, so the formulation receives the ordinary unresolved mark.
Cofactors
0 / 100Magnesium, zinc, selenium, and the other blend ingredients are not established here as separately quantified complementary supports for the stated sleep purpose.
