Quercetin is a plant flavonoid found in onions, apples and capers, and it is one of the most studied antioxidant compounds in the diet. People take it in supplement form for year-round immune support and antioxidant defense, often alongside vitamin C or bromelain.* NatureBell supplies it as quercetin dihydrate from the Sophora japonica flower bud, a soy-free source, in a plain capsule.

What's inside

• 1,000 mg quercetin dihydrate per serving
• Sourced from Sophora japonica, soy-free
• 240 capsules per bottle
• Third-party tested for quality and potency
• Non-GMO, gluten-free, dairy-free and egg-free; single ingredient

How to use

Take the labelled serving daily with a meal, which helps absorption of this fat-friendly flavonoid. The 240-count bottle covers several months of daily use. Quercetin may interact with certain antibiotics and blood-pressure medications; consult your healthcare provider if you take any.

Why we carry it

Quercetin is commonly sold in 500 mg capsules of 60 to 120 count, so a full gram serving means two or more bottles a month. NatureBell's 1,000 mg dose and 240-count bottle offer a lower cost per gram, with independent testing and a single-ingredient label.*
