Scoring criteria

Quantity
100 / 100
The selected routine supplies 1 g of quercetin, a reasonable supplemental amount for the labelled general-purpose role; the higher allowed routine is not needed for adequacy.
Form
75 / 100
The label identifies conventional quercetin, for which no distinct absorption or tolerability advantage over ordinary forms is established here.
Convenience
63 / 100
The smallest labelled routine is 3 capsules daily in divided doses; two administrations are inferred from that direction.
Label accuracy
100 / 100
The declared serving amounts and directions are internally consistent, with no misleading claims supplied.
Purity
75 / 100
No product-specific purity testing or contaminant information is provided, so ordinary quality is unresolved.
Cofactors
50 / 100
The 788 mg of vitamin C is a meaningful supporting ingredient commonly paired with quercetin, but added benefit for this role is uncertain.
