Tag: Quercetin safety

Quercetin is a powerful plant flavonoid found abundantly in many fruits and vegetables, known for its antioxidant and anti-inflammatory properties. While consuming quercetin through diet is generally safe, supplementation involves concentrated amounts that require caution, especially for those with specific health conditions or who take certain medications. Understanding when you should avoid quercetin is crucial for preventing adverse effects and dangerous interactions.

According to research published by the NIH, adverse effects from oral quercetin supplementation are rare and mild, but serious issues like kidney toxicity have been linked to high intravenous doses. This distinction is critical to understanding what is the downside of quercetin, as risks escalate significantly with the method of administration.

Many clinical trials have safely used quercetin orally for up to 12 weeks. However, data on how long you can stay on quercetin beyond this period remains very limited. This creates a critical distinction between short-term use and long-term supplementation that requires careful consideration.
