Scoring criteria

Quantity
100 / 100
The selected routine provides 1 g of quercetin, a reasonable supplemental amount for general use.
Form
75 / 100
The label identifies quercetin but establishes no absorption-enhanced form or relevant comparative advantage, so the conventional form receives the neutral mark.
Convenience
63 / 100
Use the smallest allowed routine, three tablets daily, which provides one labelled serving; the directions say to take the tablets in divided doses.
Label accuracy
100 / 100
The supplied panel gives consistent serving amounts and directions, with no established contradiction or misleading claim.
Purity
75 / 100
The label lists ordinary excipients, but the supplied information establishes neither special purity controls nor a product-specific purity defect.
Cofactors
50 / 100
The separately quantified vitamin C and bromelain have complementary roles in this type of quercetin formula, though added benefit is uncertain.
