Category average: 74.5 / 100

The three-tablet routine supplies 1 g of quercetin, with substantial vitamin C and bromelain, but the conventional quercetin preparation has no identified enhanced-delivery form.

Scoring criteria

Quantity
100 / 100
The selected routine provides 1 g of quercetin, a reasonable supplemental amount for general use.
Form
60 / 100
This is conventional quercetin without an identified enhanced-delivery form; its limited solubility and absorption are a supported limitation versus enhanced formulations.
Convenience
63 / 100
Use the lowest suggested routine, three tablets daily, split into two administrations as the label directs divided dosing.
Label accuracy
100 / 100
The matched label gives consistent amounts and directions, with no identified contradiction or misleading claim.
Purity
75 / 100
No product-specific purity testing or contaminant evidence is provided, so ordinary quality remains unresolved.
Cofactors
50 / 100
Vitamin C at 646 mg and bromelain at 300 mg are meaningful supporting ingredients with complementary roles, though added benefit for quercetin use is uncertain.
