Bee Pollen and Quercetin, a caution.
Bee pollen naturally contains quercetin and related flavonoids, so adding a quercetin supplement increases total flavonoid intake and overlaps with bee pollen's own polyphenol load.

Caution
What is happening. Bee pollen naturally contains quercetin and related flavonoids, so adding a quercetin supplement increases total flavonoid intake and overlaps with bee pollen's own polyphenol load.
Mechanism. Quercetin is one of the principal flavonols in bee pollen, so combined intake is additive, and bee pollen also carries allergenic plant proteins that raise hypersensitivity risk independent of quercetin.
Recommendation. Account for the quercetin already present in bee pollen when adding a quercetin supplement, and note that both can trigger allergic reactions in sensitive individuals.
