What Is Quercetin?
Quercetin is a naturally occurring plant compound (a flavonoid) found in many fruits and vegetables, including onions, apples, berries and leafy greens. It is best known for its antioxidant properties and its role in supporting the body’s response to oxidative stress. Quercetin is also commonly discussed in connection with seasonal wellness and immune support. In dietary supplements, quercetin is typically provided as capsules, tablets or powders, sometimes combined with vitamin C, zinc or bromelain.
Benefits of Quercetin Supplements
Quercetin supplements are often used for antioxidant support, helping to protect cells from oxidative stress as part of a balanced lifestyle. Many people also take quercetin to support immune function and seasonal comfort, especially during times of increased environmental challenges. Quercetin is sometimes used by active individuals to support recovery and overall resilience. Because quercetin is a plant flavonoid, it is frequently included in wellness formulas together with other antioxidants and nutrients for broader support.
Uses of Quercetin
Quercetin is typically taken daily, following the dosage instructions on the label. Capsules and tablets offer convenient dosing, while powders can be mixed into water or smoothies. Quercetin is often used seasonally or during periods of higher stress, and some people combine it with vitamin C and zinc as part of immune-support routines.
