About Quercetin

Flavonol

Quercetin is one of the most abundant flavonols in the diet, found in onions, apples, berries, kale and capers. It has antioxidant and anti-inflammatory properties and is widely studied for cardiovascular and immune support.

⚠️ Too little

No deficiency disease; quercetin is not an essential nutrient.

🚫 Too much

High supplemental doses (>1 g/day) are generally well tolerated in short-term studies; long-term high-dose safety data are limited.
