Quercetin is a plant flavonoid found in onions, apples, berries and green tea. It is one of the most studied natural compounds for respiratory health. It is not in Lungora.
Antihistamine properties (stabilizes mast cells, reducing allergic airway inflammation). Antioxidant activity (direct free radical scavenging). Anti-inflammatory effects (inhibits inflammatory cytokines). Antiviral properties (some evidence for reducing respiratory viral replication).
Quercetin’s antihistamine and anti-inflammatory properties make it one of the few natural compounds with direct respiratory application beyond general antioxidant support.
Quercetin (respiratory-targeted anti-inflammatory) plus Lungora (broad antioxidant and circulation support) addresses respiratory wellness from complementary pathways. Available as a standalone supplement, typically 500mg daily.
