Overview
•All ingredients are at dosages well within established safe upper limits; quercetin 500mg daily is below the 1000mg commonly used without issue.
•Potential mild side effects include stomach upset or headache from quercetin or vitamin C in sensitive individuals; zinc at 5mg poses no risk.
•May interact with antibiotics (e.g., quinolones) by reducing absorption or blood thinners by affecting platelet aggregation; consult physician if on medications.
•Suitable for pregnancy with medical advice due to limited specific data on high-dose quercetin, though individual components are generally safe.
•Vegan-friendly with no common allergens like gluten, soy, nuts, dairy, or shellfish; low risk for sensitivities.
•Long-term use appears safe at these doses based on available studies, but monitor zinc to avoid excess if taking other supplements.
