Overview
•Quercetin at 1000mg is within safe daily limits (up to 1000-2000mg studied), but high doses may cause mild GI upset in sensitive individuals.
•Bromelain 150mg poses low risk, though it may increase bleeding risk when combined with anticoagulants like warfarin.
•Stinging nettle 100mg is safe for short-term use; avoid in pregnancy due to potential uterine stimulant effects.
•Vitamin C 250mg and pantothenic acid 200mg are well below UL (2000mg and no established UL), minimal interaction potential.
•Magnesium 66mg is low dose, safe for most, but monitor in kidney impairment.
•No major allergens or contaminants reported; gluten-free and soy-free formulation reduces sensitivity risks.
