Scientific Name

Quercetin (IUPAC: 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-1-benzopyran-4-one)

Overview

Quercetin is a naturally occurring plant flavonoid found in many fruits, vegetables, and grains, particularly in capers, onions, apples, berries, and leafy greens. It acts as a powerful antioxidant, helping to combat oxidative stress and inflammation in the body. Quercetin has garnered significant scientific interest for its potential to support cardiovascular health, immune function, and overall wellness.

Where is Quercetin Used?

  • Antioxidant and anti-inflammatory dietary supplements

  • Immune support formulations

  • Cardiovascular health supplements

  • Allergy relief products

  • Functional foods and beverages for enhanced nutritional value

How Does YourHappyLife Use Quercetin in Supplements?

How Does Quercetin Work?

  • Antioxidant Protection: Neutralizes free radicals and reduces oxidative damage at the cellular level.

  • Anti-inflammatory Action: Modulates inflammatory pathways, decreasing the activity of enzymes and cytokines involved in inflammation.

  • Immune Support: Enhances immune system activity and may help reduce the severity of allergic responses.

  • Cardiovascular Health: Improves blood vessel function and may support healthy blood pressure levels.

Recommended Dosage and Use

Typical quercetin supplement doses range from 250 to 1000 mg daily. Dietary intake from food is estimated at 10–500 mg per day, but higher amounts may be used in supplement form for targeted benefits. For optimal absorption, quercetin is often paired with vitamin C or bromelain. Take with meals unless otherwise directed by a healthcare professional.

Safety, Side Effects, and Interactions

Quercetin is generally recognized as safe (GRAS) and well tolerated. Mild side effects may include headache or gastrointestinal discomfort at higher doses. Quercetin may interact with some antibiotics and blood pressure medications. Pregnant or breastfeeding women, and those on prescription medications, should consult a healthcare provider before use.
