Safety of Quercetin

Quercetin is generally considered safe for most people when consumed in amounts commonly found in food and as a dietary supplement for short periods. The most common side effects, typically associated with high doses (over 1,000 mg per day), are mild and include headache, stomach upset, and tingling sensations.

However, significant safety concerns involve potential drug interactions. Quercetin may inhibit enzymes that metabolize certain prescription drugs, potentially altering their effectiveness. It can enhance the effect of blood thinners like warfarin, increasing bleeding risk, and may interfere with the absorption of some antibiotics. Due to limited safety data, pregnant and breastfeeding women and individuals with kidney disease should avoid supplementation. Consulting a healthcare provider before use is crucial, especially for those on medication.
