Potential Benefits of Quercetin

Quercetin is widely known for its antioxidant properties, helping to neutralise free radicals that can damage cells. Research suggests that quercetin supports the normal function of the immune system, particularly during seasonal challenges.* It also contributes to normal respiratory function, making it a valuable addition to your year-round wellness routine.* Additionally, quercetin's anti-inflammatory properties may support cardiovascular health and exercise recovery. When combined with pterostilbene, another potent antioxidant found in blueberries, this formula provides comprehensive antioxidant support. Pterostilbene is recognized for its bio-available antioxidant activity, offering complementary benefits.

What is Quercetin?

Quercetin is a flavonoid antioxidant naturally present in many fruits, vegetables, and herbs, such as apples, onions, and green tea. It belongs to a class of plant compounds noted for their ability to support the body's natural defences against oxidative stress. However, standard quercetin has limited bioavailability—the amount that reaches your bloodstream. That's why the advanced formulation in Dr. Mercola Quercetin & Pterostilbene Advanced uses a quercetin phytosome complex, designed to significantly enhance absorption compared to conventional quercetin supplements.

How to Choose a Quercetin Supplement

When selecting a quercetin supplement, consider the form and dosage. Standard quercetin often appears as quercetin dihydrate, but absorption may be limited. Phytosome technology, as used here, binds quercetin to phospholipids for enhanced delivery. Look for dosages typically ranging from 250 mg to 500 mg per serving. Dr. Mercola's formula provides 500 mg of quercetin phytosome complex per serving. Additionally, check for certifications: this product is non-GMO, gluten-free, and soya-free, making it suitable for many dietary needs. The inclusion of trans-pterostilbene further distinguishes this formula by adding a complementary antioxidant.

Recommended Dosage and Usage

The recommended serving for Dr. Mercola Quercetin & Pterostilbene Advanced is two capsules per day, providing 500 mg of quercetin and 50 mg of pterostilbene. For best absorption, take with a meal containing fat, as quercetin is fat-soluble. Consistency is key to experiencing the potential benefits. This product provides a 30-day supply at the suggested serving size.
