A clearly quantified, practical quercetin dose with substantial supporting vitamin C and bromelain, though no distinctive quercetin delivery form is established.

Scoring criteria

Quantity
100 / 100
The selected routine provides 1 g quercetin, a reasonable supplemental amount for the stated general use.
Form
75 / 100
The label identifies conventional quercetin but no differentiated delivery form; no relevant comparative absorption advantage or limitation is established.
Convenience
70 / 100
The smallest labelled routine is 3 capsules once daily, providing 1 g quercetin; the label permits a second daily dose, which is not needed for this assessment.
Label accuracy
100 / 100
The high-confidence matched panel quantifies the principal ingredients, and no concrete label contradiction or misleading claim is evident.
Purity
75 / 100
No product-specific purity testing or defect is supplied, so the formulation receives the ordinary unresolved mark.
Cofactors
50 / 100
The separately quantified vitamin C and bromelain have complementary roles at meaningful amounts, but added benefit for this purpose is uncertain.
